Build

Plans show which assets exist and roughly where — they are not a survey and they do not include private assets on your side of the meter. Retic mainline, pool plant power, shed subcircuits and old soakwell connections will not appear.

These fees, bonds and conditions are City of Stirling's. Every WA local government sets its own under its own thoroughfares local law, and the amounts differ. Use this to learn what to ask about, then confirm the current figures and forms with your own council.

This is an arboriculture consultancy's own blog, used here because there is no free authoritative summary of the standard. The standard itself is a paid purchase from Standards Australia. Treat the numbers as a guide for planning your own protection fencing, and get a consulting arborist's report if a council-controlled or significant tree is close to the works.

These thresholds bite at a workplace, which includes any job someone is paid to do on your block. A homeowner working unpaid on their own home is in a different legal position but still has disposal duties and the same lungs.

Red Hill serves the eastern metropolitan councils. Other Perth facilities have their own rules and some require a booking or a waste acceptance certificate for asbestos-contaminated soil — ring before you load the trailer.

Member council rates apply to residents of the EMRC member councils. If you are outside that catchment you pay the commercial rate, which changes the arithmetic — check the equivalent page for your own regional council.

Because green waste attracts no discount here, a northern suburbs job is usually better off sending clean garden organics to a commercial composter or mulcher and keeping the tip run for the streams that have nowhere else to go.

Californian, so invert the calendar. Its advice to spray in late summer when the plant is moving carbohydrate to the roots means roughly February to April in Perth, not August. Ignore the US product names and read the label of whatever you buy here; Perth soil temperatures also mean the solarisation window is realistically December to February.

Northern hemisphere timing again. The biology and the number of repeat applications transfer exactly; the months do not. Kikuyu is a common and useful lawn grass in Perth, so treat this as a removal manual, not a verdict on the species.

The permit is issued by your local government, and whether a particular structure needs one is a question for their building surveyor. Confirm the current fee and the requirement with your council before you budget it.

BYDA returns asset owner plans up to the property boundary. Everything past the meter — the retic mainline, the pool pump feed, the unpermitted power run to the shed — is private and is not on any plan. That is your problem to locate.

Published 11 February 2014 and last updated 25 November 2024. It cites regulation numbers from the superseded Occupational Safety and Health Regulations 1996 (regulations 3.111 and 3.21); the current duties sit in the Work Health and Safety (General) Regulations 2022. The technical guidance is what WorkSafe still publishes and still expects, but do not quote the regulation numbers at anyone.

The SWMS duty binds a person conducting a business or undertaking, not a homeowner working on their own home. The list is still the best available checklist of what counts as genuinely dangerous work, and any contractor you hire owes you one.

BYDA returns plans from participating asset owners only. It will not show privately owned assets — the previous owner's shed power, an old bore line, an abandoned soakwell, unregistered poly. Those are your problem and they are found by hand digging and by your site analysis, not by BYDA.

The distances are measured from the asset, not from the manhole lid you can see, so you need the actual alignment from your BYDA plans first. Applications tied to a residential building are lodged through BuilderNet rather than the general form.

This is a road specification written for smooth drum rollers and padfoot compactors. The layer thicknesses assume that plant. Behind a hand-guided plate compactor, halve them — 150 to 200 mm compacted lifts in sand is the realistic domestic equivalent.

Version 3 dated 10 April 2026 — check you are reading the current version before you rely on a number. Local planning schemes and local development plans can vary these provisions, and failing deemed-to-comply is not illegal, it just means a development application and an assessment against the design principles.

British site. It sets its datum off the damp proof course and drains everything to gullies; in Perth you are far more likely to be falling to a soakwell or to a garden bed. Confirm the clearance your own wall construction needs below the DPC and weep holes before you fix a finished level, and treat its drainage-to-gully assumptions as a Perth soakwell problem instead.

It specifies DTp Type 1, a British graded aggregate that is not sold here. The Perth equivalent is compacted crushed limestone, which self-cements when laid damp and compacted in layers. Ignore any frost and freeze-thaw commentary entirely.

Written for developments large enough to employ a geotechnical testing regime, and priced accordingly. For a suburban garden the free Main Roads WA Specification 302 gives you the WA-specific layer thicknesses and Perth sand density targets without the cost — buy AS 3798 only if you are working to someone else's specification that names it, or check whether your local library offers Standards Australia reading-room access.

BYDA returns plans from asset owners who are members. It does not cover private assets on your side of the meter — the retic mainline, the pool pump feed, the cable someone ran to the shed, an abandoned soakwell. Those you have to find yourself.

SafeWork NSW is the New South Wales regulator; in WA the regulator is WorkSafe WA. The wording comes from the national model work health and safety regulations, so confirm the exact WA reference with WorkSafe WA before relying on it for work you are paid to do. The physical controls it describes apply on any block, in any state.

The page is an awareness hub and does not publish exclusion-zone distances in metres. Ring Western Power for the approach distance that applies to your situation — do not estimate it by eye from the ground.

These are one national hire company's terms, not law, and every depot's contract differs. Use it as the list of questions to ask, then read the actual contract you are being handed in Perth.

Rates themselves are set per depot and are not published on the page, so this gives you the structure, not the Perth price. Ring three Perth branches for the machine you actually want and compare the total, including delivery and pick-up.

Written by a hire company to sell hire. The technique is sound; the implied 'anyone can do this' framing is not a substitute for practising on something that does not matter.

This binds you only if you are in the City of Stirling. Councils differ materially — Cockburn uses a different design storm and a different formula. Use this to learn the shape of the rules, then download your own council's version.

The version accessible in August 2026 carries a version date of 8 November 2019 and describes itself as a guide only. Confirm the current figures with Cockburn before you rely on them.

NCC 2025 was published on 1 May 2026 and Western Australia adopted it from 1 May 2026 with a 12 month transition period, so NCC 2022 may still apply to work approved before the changeover. The Part 3.3 drainage figures quoted here are identical in both editions.

A transitional code of practice carried across to the Work Health and Safety Act 2020, so some regulation numbers refer to the old framework. Its duties bind a person conducting a business or undertaking; a homeowner digging on their own block is not automatically caught by them, but sand collapses on homeowners exactly as readily.

BYDA covers member utilities in public areas. It does not map privately owned services inside your boundary — the old power run to the shed, the previous owner's poly, or an abandoned soakwell. Those you find by hand.

A JavaScript map application, so it needs a current browser and will not open usefully on a phone in the field. It gives a modelled estimate, not a measurement of your block.

A manufacturer's page, so treat it as a product reference rather than design guidance. It does not list grades or roll sizes — those are in the technical data sheet it links to, and you should ask the supplier which grade suits fine Perth sand rather than guessing.

The version current when this was checked started on 23 July 2026, suffix 04-ae0-01. Always download the version marked Current rather than a cached PDF, and read the exemption alongside your local government's planning rules, which are separate and often tighter.

This is one council's policy. The 0.5 m building permit trigger comes from state regulation and is the same everywhere in WA, but the setback table, street-setback heights and screening rules are Joondalup's own. Get your own council's equivalent page in writing before you design.

Published 2014 and last updated November 2024, so it still cites the old Occupational Safety and Health Regulations 1996 numbering (regulations 3.111, 3.112) rather than the Work Health and Safety (General) Regulations 2022 that now apply. The regulation numbers have moved; the engineering advice and the soil-specific batter slopes have not.

Registration is required to download — the manuals themselves cost nothing. These are engineering design documents aimed at architects, engineers and builders, not step-by-step installation guides, and they assume you have already decided the wall needs designing.

North American document in imperial units. Ignore the freeze-thaw and frost-depth material entirely. Substitute compacted crushed limestone for the crushed-stone levelling pad, since that is the Perth standard and it self-cements when laid damp and compacted in layers. Its drainage advice is if anything conservative for Perth sand — but the sand is exactly why the geotextile separation matters more here, not less.

AS 4678 applies to earth-retaining structures between 800 mm and 15 m in height, so it does not cover the sub-800 mm walls that make up most suburban landscaping. Below that height you are relying on the manufacturer's system limits and good practice, not a standard.

The page points to the Residential Guidelines for Designers for the actual clearance dimensions rather than publishing them inline, so you will need to lodge an enquiry or read that document for the numbers that apply to your pipe and depth.

Exempt from licensing is not exempt from a building permit. A wall retaining more than 0.5 m still needs a permit, still needs to satisfy the permit authority, and the owner still carries the liability if it moves.

This is a Perth stone supplier's own product page and it exists to sell blocks. The dimensions and weights are the useful part and match what the trade uses; price-check against other WA block yards, and note the page publishes nothing about footings, drainage or maximum heights.

This is the City of Canning's specification for work in the road reserve, last updated November 2020, and it binds you only within that City and only for a crossover. Every Perth council publishes its own version with slightly different numbers. Use it as the benchmark for private paving on your own block, but read your own council's document before you touch the verge.

Stated on the sheet as correct as of July 2025. It is written for crossovers in the City of Wanneroo road reserve, where a street and verge bond permit also applies. The material and bedding requirements transfer directly to private paving; the approval, bond and subsidy provisions do not.

The 150 mm figure is the base under an asphalt crossover in an older, established Town, not a universal Perth number. It also confirms that approval must be obtained before crossover construction begins — a rule that applies everywhere in Perth, in every council, with the fee and process varying.

A highway specification, written for graders, water carts and smooth drum rollers. The material definitions and the layer rules are exactly right for a garden; the density testing regime and the hold points are not. Behind a hand-guided plate compactor, work in much thinner lifts than 250 mm — see the earthworks lesson.

An ACT government specification, so the referenced companion documents (MITS 02, MITS 04) are Canberra's. It also declares crusher dust and dolomite unsuitable as bedding material — worth knowing in Perth, where limestone cracker dust is sold cheaply and frequently used as a bedding layer despite the fines washing out and the surface setting hard.

North American. Ignore every reference to freeze-thaw, frost depth and drainage layers designed for saturated clay sub-grades — a Perth sand sub-grade drains faster than the base above it. Substitute compacted crushed limestone for the crushed aggregate base it describes, and read its Proctor percentages as the equivalent of the 95% maximum dry density your council asks for.

British site, working to BS 7533 rather than Australian practice, and its 25 to 40 mm finished bedding range is slightly deeper than the 25 mm plus or minus 5 to 10 mm that Perth councils specify. Use the technique and the screed-rail method; use the Australian depth.

These duties bind a person conducting a business or undertaking, not a homeowner cutting their own pavers on their own block. The dust does not know the difference. Water suppression or on-tool extraction plus a properly fitted P2 respirator is the minimum either way.

This is a supplier's own product page, not an independent source, and it is here because it publishes real Perth ordering constraints rather than because the advice is authoritative. The page shows a price but does not state the unit it applies to, so ring for a delivered price per cubic metre or per tonne before you budget, and price-check at least two Perth soil yards or quarry suppliers.

It is written for a PCBU — a person conducting a business or undertaking. A homeowner cutting their own pavers on their own home is not bound by these duties, but the exposure and the disease are identical.

This is a paver manufacturer's marketing page and it recommends its own jointing products. The sequence and the dimensions match Perth trade practice; treat the brand names as advertising.

North American document in imperial units. Ignore the freeze-thaw and ASTM C936 durability material entirely. Convert its base thicknesses to metric (100 mm minimum for pedestrian areas, more under vehicles) and read crushed aggregate base as compacted crushed limestone, which is the Perth standard. Its 1/16 to 3/16 inch joint recommendation is 1.5 to 5 mm, which brackets the 2 to 3 mm used here.

North American. The freeze-thaw driven detailing does not apply, but the mechanics do, and they matter more here than there — a Perth sand subgrade offers almost no lateral resistance, so an unrestrained edge creeps faster than the document assumes.

Seventh edition, February 2010, so check any Australian Standard it references against the current version. CCAA's own server blocks automated access, so this is the identical document hosted by a concrete contractor; the CCAA branding, ABN and office list are intact in the file.

Written for the whole country, and Perth sits at the severe end of every variable it lists — hot, dry, and windy in the afternoon. Treat its 'precautions' column as your default from about October to April, not as an exception.

This is the City of Stirling's spec and it binds work in the Stirling verge. Other Perth councils differ in detail — check yours before you build in the road reserve. Away from the verge it is not law, but it is a defensible standard to build your own driveway to.

Revised in 2019 under the old Occupational Safety and Health Act 1984, which has since been replaced by the Work Health and Safety Act 2020 and the WHS (General) Regulations 2022. The techniques and controls still stand; for the current legal duties on silica, read it alongside WorkSafe's crystalline silica pages.

Written for a bagged product, but the cement chemistry and the hazard are identical in a premix truck load. Your supplier will have its own SDS for the exact mix — ask for it when you order.

This is a Perth installer's own sales page and it is selling you liquid limestone. Treat the technical description as reliable and the enthusiasm as advertising. Cross-check the build spec against the City of Stirling crossover specification above, which sets a 100 mm minimum thickness and requires manufacturer's specifications for vehicular traffic.

Built around Cement Australia's bagged products, so the bag counts are only relevant if you are hand-mixing. The volume figure is the part you want for a premix order.

Revised October 2020, so its deck-to-wall attachment section describes the older 190 x 45 mm waling plate rule rather than the current NCC Part 12.3 detail — use the NCC for that. Its species appendix also still marks jarrah as termite resistant, which is true horticulturally but is no longer the position under AS 3660.1:2014 for compliance purposes. Skip the bushfire notes on NSW and South Australia; WA has its own BAL process.

Issued April 2017 to announce the move from the 2000 to the 2014 edition of AS 3660.1, so the transition dates in it are historical. The substance — WA as a termite risk area, the jarrah delisting, and the reticulation requirement for concealed perimeter soil — is still the current position and is repeated in NCC Part 3.4.

Western Australia adopted NCC 2025 on 1 May 2026 with a 12-month transition, so until 30 April 2027 a permit may be assessed against either NCC 2022 or NCC 2025. Part 12.3 reads the same in both editions, but confirm which edition your permit authority is applying.

The version read for this lesson was the official consolidation as at 23 July 2026, PCO suffix 04-ae0-01. Always download the version marked current rather than a cached PDF. A ground-level timber platform may still be treated as landscaping by some councils, which is a local decision, not a Schedule 4 exemption — get it in writing.

This is one local government's guide. The R-Codes visual privacy provisions are state-wide, but the 20 square metre and 500 mm triggers, the setback table and the screening rules are Joondalup's own application of them. Get your own council's equivalent page or a written response before you set the deck height.

Not needing a registered building contractor is not the same as not needing a building permit, and it is not the same as being allowed to build it yourself for someone else. If you are doing the work on your own home you may also need owner-builder approval from the Building Services Board depending on the value of the work — check before you start.

Published September 2019 and not updated since. It still refers to a building licence rather than a building permit, and quotes the old $20,000 registered builder threshold, which rose to $50,000 for Class 10a work on 1 July 2026. The maintenance and failure-mode content is unaffected.

Manufacturer instructions are brand-specific and non-compliance voids the warranty, so use your own supplier's sheet for the actual build. Two ModWood rules apply everywhere in coastal Perth: use stainless steel fixings and stainless or KSL-series clips around pools and within 1 km of salt water, and fix boards when the ambient temperature is below 25 degrees and the boards are not sitting in full sun.

Written for workplaces under the WA work health and safety framework, so the duties bind employers and people conducting a business. On your own block they are not enforceable against you, but the biology is identical. Note also that WA is transitioning from workplace exposure standards to the national workplace exposure limits, with the current standards applying until 1 December 2026.

Written about Class 1a houses and dated October 2019, so it predates NCC 2025. The method, the terrain and shielding traps and the responsibilities it describes apply equally to the Class 10a patio or carport attached to your house, because AS 4055 covers Class 1 and Class 10 structures within the same geometric limits.

Dated May 2021 and refers to NCC Volume Two Part 3.4.4 and Table 3.4.4.7, which is 2019 numbering. NCC 2025 applies in WA from 1 May 2026 and the clause numbers have changed; the technical argument has not.

Published November 2025. It states it does not take precedence over the Gas Standards (Gasfitting and Consumer Gas Installations) Regulations 1999 or the appliance manufacturer's instructions, and manufacturers routinely require larger clearances than the minimum.

Issued by Timber Queensland and revised March 2014, and the copy that is publicly downloadable is hosted by a timber merchant rather than by Timber Queensland itself, whose data sheets have moved behind a member login. It is a national timber design document, not a WA one — confirm your own wind classification rather than assuming the low wind table applies, and confirm your council will accept it, because most Perth councils want structural engineer's details regardless.

One council's rules, correct as at July 2025, and its numbers are not universal — Wanneroo requires eaves and gutters set back 500 mm from a boundary where the R-Codes say 450 mm, and its setback table is written for R20 and R30 lots. Use it to learn the shape of the application, then get your own council's requirements in writing.

Recent reforms let a householder do a short list of minor tasks such as replacing a showerhead or clearing a blocked pipe. Running a new water line to a garden sink or connecting a waste to the sewer is not on that list.

This edition dates from October 2006 and cites regulation 3.64 of the Occupational Safety and Health Regulations 1996, which has since been replaced by WA's work health and safety regime. Treat the distances as the working benchmark, and confirm the requirement for the specific line over your block with Western Power on 13 10 87 before you plan the lift.

American document, US units first. Every chart is repeated in SI on pages 107 to 119, so read those. Ignore the pipe types entirely — Schedule 40, Class 200 and Type K copper are not what Perth retic shops sell. Substitute the Australian pipe data in the Vinidex and Iplex resources below, and treat its "water purveyor" advice as pointing at Water Corporation.

Built for rural pipelines, so the shortest length in the table is 100 metres and the shortest garden run you will design is more like 30. Reading a 100 metre row for a 30 metre run is conservative in your favour. It also models an open-ended pipeline with one outlet, not a lateral with six sprinklers on it, so use it for mainlines and single runs rather than for sizing laterals.

Californian, in psi and gallons per minute, and its pipe tables are US pipe. Convert: 1 psi is 6.9 kPa, 1 US gallon per minute is 3.79 litres per minute, and 5 ft/s is 1.5 m/s. Its watering advice assumes no roster at all, which is not your situation in Perth.

Endorsement means the business has been appointed to deliver the Water Corporation program, not that it is the cheapest or the best designer. The directory also lists interstate members, so filter by state.

Aimed at people already in the trade — it recommends two to three years' irrigation experience or a Certificate III. If you are designing one suburban block, the free Rain Bird manual above teaches the same hydraulics and costs nothing.

Most Perth properties still have a mechanical meter. The Perth smart water meter program is a trial of up to 16,000 properties running 2023 to 2026, so do not plan around a live L/h display until you have opened your meter box and looked.

Accreditation is a trade association membership, not a state permit. Ask specifically for experience in your suburb's aquifer conditions, and ask for the bore log in writing as part of the price.

The 10 mm per watering day figure is a Perth default for a two-day roster on sandy soil, not a per-plant requirement. Hydrozoning exists precisely so that different stations get different depths and different frequencies — use these rates to convert your chosen depth into minutes, not as a target for every station.

The exemption is time-limited from the day of planting: up to 42 days between 1 October and 31 March, up to 35 days between 1 April and 30 September. Watering outside the conditions of an exemption risks a $500 fine, so program the controller to revert to the roster on the day it expires rather than trusting yourself to remember.

The project dates from 2013 and the greywater and bore components are more than a suburban renovation needs. Read it for the hydrozone-to-station logic, which is unchanged, not as a shopping list.

The water ratings describe established plants. Everything needs more water for its first summer, which is what the establishment program and the watering exemption are for.

This is a manufacturer's own DIY guide, so the product recommendations are advertising and the flow figures are for that brand's nozzles at their rated pressure. It covers spray pop-ups on PVC only — no rotors, no dripline — and it does not address mixing emitter types, hydrozones or aspect. Use the published flow of the nozzle you actually specify.

Endorsement means a business has been appointed to deliver the program, not that it is the best designer or the cheapest. Filter by state — the directory lists members outside WA.

Explicitly not entry level: it recommends two to three years of irrigation experience or prior formal training such as a Certificate III. For a homeowner designing one garden, the free alternative is the Waterwise Irrigation Design Shop directory above — a design review costs a fraction of the certification and answers your actual question.

The 10 mm per watering day figure behind those run times is a Perth and Peel default for a two-day roster on sand. It is a scheduling default, not a plant water requirement — hydrozoning changes it, and Lesson 5 of this mini-course recalculates it from your own catch-cup data.

Written for non-residential sites such as shopping centres and caravan parks, and aimed at grounds staff. The emitter reasoning, pressures and run-time tables transfer directly to a suburban block; the vandalism and site-management sections do not.

A manufacturer's own brochure, so treat it as a specification sheet rather than impartial advice. Competing Australian products from Toro, Rain Bird, Antelco and Pope publish equivalent tables — the point is to read whichever table belongs to the product you actually buy, because flow, spacing and run length differ between them.

Written for a national audience, so its example watering intervals are for a Sydney climate and its soil advice is generic. Ignore both and use the Perth numbers from the Water Corporation page above.

Imperial units throughout. Convert: 30 psi is about 207 kPa, 40 psi about 276 kPa, and 1 foot is 0.305 metres. Stryker's rotor spacing rule in metric is roughly spacing in metres must not exceed inlet pressure in kPa divided by 23 — so 300 kPa at the rotor caps you at about 13 metres. Ignore the American backflow and code references entirely; WA requirements are covered in Lesson 6 of this mini-course.

Imperial units and North American products. The spacing and matched precipitation principles are physics and transfer unchanged; the specific nozzle model numbers do not. Perth's summer sea breeze is stronger than most of the conditions this page assumes, so if anything tighten spacing rather than stretch it.

Josh's House was built new on a Fremantle lot with a bore and a greywater system, so the water sources are not typical. Greywater reuse in WA is separately regulated — do not copy that part of the schedule without checking the current requirements with your local government environmental health officer.

The directory covers several states, so filter to Western Australia. Endorsement means the business has been appointed to the program, not that it is the cheapest or the best designer — get two opinions on anything expensive.

The 10 mm per rostered day target is a Perth and South West default for sandy soil on a two-day roster. It is a scheduling starting point, not a plant water requirement, and the bands are wide enough that two stations built with the same nozzle can sit at opposite ends of one.

It does not tell you how many cups to use, how to calculate distribution uniformity from the readings, or that a 15-minute test run has to happen inside your rostered watering window. Pair it with the Irrigation Association audit guidelines below for the statistics and with the testing rules page for the legalities.

Published in 2022, when the Perth and Mandurah bore roster was aligned to two days a week. The watering rules and the run-time table still match Water Corporation's current pages, but check the rebate and free-catch-cup offers against the live Water Corporation site before relying on them.

American, and in imperial units — its precipitation rate formula is in inches per hour from millilitre catches. Ignore it and use the metric shortcut in this lesson instead, because 1 mm of depth is 1 litre per square metre and the conversion is unnecessary here. The uniformity maths, the run time multiplier and the fieldwork protocol are unit-free and transfer to Perth without change.

Written for a US market with no equivalent of the Perth roster or the winter switch-off, and its worked examples are in inches and gallons. The bigger adaptation is the soil: its cycle-and-soak advice assumes runoff is the default risk, whereas on deep Perth sand the default risk is the opposite — water dropping straight past the root zone. Apply its cycle logic to your slopes, water-repellent patches and compacted areas, not to your whole garden.

The two-minute allowance is for fault-finding and flushing, not for a catch-cup test. A 15-minute catch-cup run is a watering event and has to happen as your once-per-rostered-day watering, before 9am or after 6pm.

Apply on the day the lawn or garden goes in, because the exemption is counted from the installation date whenever you lodge it. Breaching the exemption conditions risks a $500 fine, and the page is explicit that the breach belongs to the property owner, not the contractor who laid the turf.

Endorsement means the business has been appointed to deliver the Waterwise programs, not that it is the cheapest or the best. The list includes members outside WA, so filter by suburb.

Written for plumbers and builders dealing with Water Corporation, not for homeowners. Section 4 is the part that matters for irrigation; most of the rest is about water and sewer connections for new developments. It also confirms Water Corporation does not manage or accept test reports for zone or individual backflow devices — those sit under the plumbing standards and the Plumbers Licensing Board instead.

Consolidated as at 1 July 2026. Read the current HTML version linked from this page, not a cached copy — these regulations were amended by SL 2026/48 and SL 2026/95 during 2026, and the plumbing standards they adopt changed on 1 May 2026.

The NCC is adopted state by state with variations. In WA the plumbing standards are set by regulation 48 of the Plumbers Licensing and Plumbing Standards Regulations 2000, which adopts Section A and Parts B1, B2, B3, B5, B6, C1 and C2 of the Plumbing Code — so not every part of Volume Three applies here.

American, and dual-unit. Read the metric figures in brackets and ignore the imperial ones. Substitute Australian metric poly and AS/NZS 1477 PVC pressure pipe for the US pipe schedules — the internal diameters differ, so use your supplier's tables for the actual numbers and take only the method from here. It also assumes 117 V or 230 V power and a US electrical code; in WA the 240 V side of the controller is licensed electrical work.

This is an irrigation manufacturer's own page and it is written around Holman controllers and valves. The wiring logic and the connector rule are universal; check the cable size and maximum run length against your own controller and solenoid manufacturer's data, because solenoid current draw varies between brands and a less efficient solenoid needs heavier cable for the same distance.

Endorsement means the business has been appointed to deliver the program, not that it is the best designer or the cheapest. It also lists members outside WA, so filter by postcode. A Waterwise Garden Irrigator is not a licensed plumbing contractor — check both licences if you want one business to do the cut-in as well as the retic.

Course fees are quoted per course on enquiry and are not published as a single price, so ask for a current quote from the Perth office. The free alternative that covers most of the same design ground is the Rain Bird Landscape Irrigation Design Manual listed above — it will not give you a qualification, but it will teach you the method.

BYDA returns plans from participating asset owners only, and the plans show approximate positions. They are not a substitute for hand-digging or vacuum excavation to expose a service before you trench across it, and they will not show private cabling installed by a previous owner.

The exemption covers new planting only. Everything else on the block stays on the normal roster at the same time, which means running the new area on a separate program or a separate controller output rather than lifting run times across the whole system.

American, and its savings claims assume unrestricted watering. In Perth you are capped at two rostered days, so a weather-based controller can only shorten or skip waterings, never add them — which removes a large share of the savings the EPA figures are built on. There is no Australian equivalent label, so treat WaterSense as a feature checklist rather than proof a unit suits WA.

A manufacturer's own site, listed here because it hosts the documentation rather than as a product recommendation. Hunter, Rain Bird and Toro host equivalent manuals for their own ranges; buy on features and station count, not on brand loyalty.

Checked on 2 August 2026, this page states "This offer is currently closed" — the last round covered services completed between 1 September 2025 and 31 May 2026, and properties that claimed in 2024/25 were excluded from 2025/26. Confusingly, the Waterwise offers index still displays it as open, so trust the rebate page itself and confirm the next round before you book work expecting a rebate.

The two-minute allowance covers fault-finding and flushing, not a catch-cup test. A 15-minute uniformity run is a watering event and must be your one watering for that rostered day.

It does not tell you how many cups to use or how to calculate distribution uniformity from the readings. Pair it with the Irrigation Association audit guidelines below for the statistics and the fieldwork protocol.

American and imperial: pressures in psi, spacings in feet, and a precipitation rate formula based on millilitres and square inches. Ignore that formula and use the metric shortcut from lesson 5, where 1 mm of depth is 1 litre per square metre. The protocol, the uniformity maths and the run time multiplier are unit-free and transfer to Perth unchanged.

Written for candidates sitting an American certification, so the first six pages are exam administration you can skip, and the pressure fields are in psi — write kPa on them and note the change. The rotor scheduling worksheet assumes a restriction of watering every third day; Perth is two rostered days a week, so use your own roster.

American, and its scheduling assumptions come from a market with no equivalent of the Perth roster or the winter switch-off. Ignore the winterisation material, read square footage as square metres, and treat the utility-locate instruction as a Before You Dig Australia enquiry rather than the US 811 service it names.

A manufacturer's technical note, so it is written around its own pipe and cement types. The 24-hour rule before straining a joint is the one people break; on a Perth summer job that means you glue laterals in the afternoon and pressure-test the following morning, not an hour later.

An irrigation manufacturer's own page, written for spring maintenance on an existing system rather than for commissioning a new one. On a new install the timings are far too short — flush until the water runs visibly clear, which after a limestone-country trench can take a minute or more per lateral.

Written as a duty on employers and businesses. If you are working on your own block those duties do not bind you, but the physiology does, and the risk is worse because nobody is watching you. Tell someone when you start and when you expect to finish.

Plans come from participating asset owners only and show approximate positions. They are not a substitute for hand-digging to expose a service before you trench across it, and they will never show private cabling or pipework installed by a previous owner.

Endorsement means a business has been appointed to deliver the Waterwise programs, not that it is the cheapest or the best. The directory lists members outside WA, so search by suburb and radius rather than browsing the full list.

Long consolidated instrument — use your browser's find function for 'electrical work means' rather than reading it front to back. Check the version banner at the top; consolidations are re-issued when the regulations are amended.

It is a JavaScript search application, so it will not open in a text-only browser and there is no direct link to an individual result. Search by the licence number printed on the quote.

Written for environmental impact assessment near threatened wildlife, not for suburban gardens. The design principles in Appendix A transfer directly; the assessment framework, the 20 km habitat trigger and the taxa-specific appendices do not apply to a Perth block unless you are on the coast near turtle or seabird habitat.

574 pages written for licensed trades, and expensive. For a homeowner the sane approach is to ask your electrical contractor for the depth and installation requirements that apply to your job rather than buying the standard — and to distrust any burial depth you read on a blog.

Covers up to 0.6/1 kV a.c., so the tables are built around mains circuits. The voltage drop mathematics applies to a 12 V circuit unchanged, but the percentage limits quoted in the standard are not the right target for extra-low-voltage lighting — a 5% drop on 12 V is only 0.6 V, and LED fixtures tolerate more than that.

A US lighting retailer's own learning centre, so it is manufacturer content — treat the product recommendations as advertising. Mains is 120 V there and 230 V here, so ignore the 118–125 V outlet reading; measurement on the 12 V side is identical. Their working range of 9–15 V is for their own LED fixtures — check the datasheet for the ones you buy.

A manufacturer's catalogue, so it is selling you something, and the page states the system is not compatible with other brands — a plug-and-socket system locks you into that brand's connectors. It also caps you at whatever the controller is rated for, which is usually well short of what a large garden needs.

The plans show registered network assets, not private cables. Anything a previous owner ran to a shed, a pool pump or an old garden light is invisible to BYDA and will not appear on any plan — that is what a cable locator and careful hand digging are for.

The mulch depth here reads 10 cm while the utility's own soil page says 5–10 cm. Treat 10 cm as the target for coarse woody mulch over open beds and less where you are mulching up against plant stems.

This is a Perth soil supplier's own page and it recommends its own branded products alongside the generic advice. The rates and the reasoning match what the trade uses; treat the product names as advertising and price-check per cubic metre against two other soil yards before you order.

Written for WA broadacre cropping. The 100 t/ha figure is for spreading clay-rich subsoil, not a bagged product — 100 t/ha works out to 10 kg per square metre, which is why it lands inside the 5–15 kg/m² range quoted for kaolinite and nowhere near the bentonite rate. Ignore the machinery and the yield economics.

Agricultural document aimed at medium to high rainfall cropping country. The principle and the direction of the numbers transfer to a suburban bed; the delvers, spaders and mouldboard ploughs do not.

The soil-borne species is the one that matters here. HealthyWA's companion Legionnaires' disease page (healthywa.wa.gov.au/Articles/J_M/Legionnaires-disease) names Legionella longbeachae as the most common strain in Western Australia and reports around 60 diagnosed cases a year against around 12 for the cooling-tower species, L. pneumophila. The handling precautions on this page are the defence.

Water Corporation does not grant these to licensed bore users — the page directs licensed groundwater users to the Department of Water and Environmental Regulation on 1800 508 885. Figures checked 2 August 2026; the exemption periods are reviewed and can change between seasons, so read the page on the day you apply rather than trusting this summary.

The definition of waterwise is regional. For Perth and the South West it means the plant will hold up on one watering a week in summer once established; further north it means every four days. Establishment ratings are a separate thing again — a waterwise plant still needs full establishment watering in its first year.

Verges are council land and most Perth councils have their own verge treatment policy covering permitted height, sightlines and species. Check yours before you plant the strip out the front — this page is Water Corporation guidance, not planning approval.

It is a species directory, not a how-to. Kings Park grows in a curated, staffed environment on Spearwood-type soils over limestone; a Bassendean sand block in Gosnells is a harsher site than the display beds suggest.

Endorsement is a Waterwise program badge, not a quality guarantee on the stock itself. You still inspect root balls yourself, and a specialist native or wholesale grower that is not on the list may hold far better stock for a native-heavy plan. Note that the page links out to Water Corporation's plant directory rather than hosting one of its own.

North American document. Ignore the fall and winter timing entirely — autumn in Perth is April and May, not October. Its 5 to 7.5 cm mulch layer is at the thin end for Perth; Water Corporation specifies 5 to 10 cm of coarse mulch here. And its once-a-week watering assumes a soil that holds water, which yours does not — use the Water Corporation exemption schedule for the establishment period instead.

Purchased here through Intertek Inform, an authorised reseller; Standards Australia is the publisher and the price checked on 2 August 2026 was AUD $154.97 including GST. The standard excludes palms, and excludes stock grown for topiary, espalier, bonsai, pollarding or coppicing.

The group's main focus is bushland management, so much of the site is about vehicle hygiene and quarantine areas rather than backyards. The relevant part for you is the sourcing advice — and it matters most if your plan includes banksias, grass trees or anything else in the Proteaceae.

Apply on the day the turf goes down — the exemption runs from the day of planting, so applying late costs you days. Water Corporation states it does not grant exemptions for properties with a licensed bore because those are managed by the Department of Water and Environmental Regulation; if you have a bore, ring Water Corporation on 13 13 85 before you order turf and confirm in writing which body handles your exclusion.

This is an industry association that exists to promote natural turf, so it will never tell you to lay less lawn or to consider an alternative surface. The species ratings are sound and match what WA farms actually supply; treat the advocacy content separately.

Membership is a trade association, not a quality certification. The list also includes growers well outside the metro area — Ord Valley at Kununurra, Down South at Busselton, True Blue at Bunbury — so filter by delivery distance before you ring.

This is a Perth turf farm's own marketing page and it states plainly that the prices are just an approximation. There is no date on the figures. Use it to sanity-check a quote and to see which line items should be on it, then ring two TGAWA growers for a current per-square-metre rate before you order anything.

Written for employers and PCBUs. If you are working on your own house the duties do not bind you, but the physiology does — and the moment you pay someone to help you carry rolls, you are in scope.

Written for the whole termite problem, not for landscapers — the landscaping material is the prevention checklist near the end. It does not publish the slab-edge inspection dimension, which sits in AS 3660.1 and in your own builder's termite documentation, so read the durable notice on your house rather than assuming a number.

Published 2015. The mulching and soil sections are still exactly right; the watering roster table at the back is dated, so take current watering days, exemptions and the winter switch-off from Water Corporation instead.

North American document — ignore the freeze-thaw sections entirely. Where it says crushed aggregate base, read compacted crushed limestone, which is the Perth standard. Its "never spike into soil" rule matters even more here, because deep sand will not hold a spike at all.

The group's main audience is people working in and around bushland, so parts of its hygiene protocol are heavier than a suburban garden needs. The sourcing advice is the part that applies to you.

These are duties on businesses and workers. A homeowner cutting their own edging is not captured by the regulations, but the dust is identical and silicosis is irreversible — treat the control measures as the standard you hold yourself to.

National service, not WA-specific, and the load is whatever the contractor chipped that day. You cannot specify species, coarseness or freshness, and you cannot get a dieback-free assurance. Fine for a back fence line; buy a graded product for the beds people look at.

The exemption carries conditions on watering times and volumes and the property owner is liable for a breach even if a contractor installed the garden — the published fine is up to $500. Read the conditions attached to your specific approval rather than assuming.

Endorsement means the business has been appointed to deliver the Waterwise program, not that it is the cheapest or the best. The list includes members in other states, so filter by location.

These duties under the Work Health and Safety (General) Regulations 2022 bind businesses and workers, not a homeowner sweeping their own paving. The exposure is identical either way, so treat the controls as the method rather than as paperwork you are exempt from.

North American document with imperial units — its washing pressures are quoted in psi and flows in gallons per minute. The cleaning chemistry and the sequence transfer directly. Ignore the freeze-thaw material, and note that Perth's limestone-based products and hard bore water make iron staining a far more common problem here than anything in the document.

Written mainly for councils, manufacturers and large installations rather than domestic gardens. The principles scale down; the measurement and certification material does not, and you do not need it for a suburban block.

Aimed at revegetation and catchment monitoring, so the site-selection and record-keeping detail is heavier than a garden needs. Take the method and the discipline, skip the monitoring programme design.

Facility acceptance, fees and free-tipping vouchers vary by local government and change without notice. Ring the facility before you load the trailer, particularly for rubble, treated timber or anything that might contain asbestos.
