When is firebreak season in WA? 2025-26 deadlines by council

Firebreak season in Western Australia is the months between when your council's annual Firebreak Notice takes effect and when the prescribed bushfire risk period ends. For most landholders that runs from 1 November through to 30 April, but the exact start and end dates are set council by council under the Bush Fires Act 1954 (WA). Miss your local deadline and you are exposed to a council infringement, a work-and-recover bill, and potential prosecution. This guide lists the verified 2025-26 deadlines for 18 WA councils and explains what "maintain" actually means once the date arrives.

The default window: 1 November to 30 April

Under section 33 of the Bush Fires Act 1954 (WA), every local government may issue an annual notice requiring owners of applicable land to install and maintain firebreaks. The Act itself does not fix a state-wide date. Instead, each council publishes a Firebreak / Fuel Hazard Reduction Notice that names:

• the date by which your breaks must be installed (the "clear by" deadline)
• the date through which they must be maintained
• the firebreak width, vegetation height, and location rules
• the maximum fine for non-compliance

The most common pattern is 1 November to 30 April, which mirrors the typical southern WA Restricted and Prohibited Burning Periods declared by DFES. That said, councils on the rangeland edge tend to bring the start date forward, and Hills councils often pull the maintenance end date earlier because cooler autumn conditions reduce risk sooner up there.

If you want to skip straight to your address, use the firebreak deadline lookup. Enter the property address and it will resolve the council and show your specific 2025-26 dates.

Verified deadlines by council

Every council below has been checked against its own current notice, and each council page carries the date of that check plus a link to the notice itself.

Council	Clear by	Maintain until	Region
City of Kalamunda	1 November	31 March	Hills
City of Rockingham	16 November	31 May	Coastal fringe
City of Swan	1 November	30 April	Hills
Shire of Mundaring	1 November	31 March	Hills

This list is deliberately short. WA councils issue each season's firebreak notice between August and October, so most 2026-27 notices are not published yet, and we would rather show you four councils we have read than thirty we have guessed. Coverage grows as the notices go up.

If your council is not listed, go straight to its website. Do not assume a neighbouring council's dates apply to you - they routinely differ by weeks.

This is a guide. Always confirm the current season's notice on your council's website before booking work.

Why councils set different dates

Three drivers explain most of the variation:

Bushfire prone area mapping. The Map of Bush Fire Prone Areas maintained by DFES designates which suburbs sit in high-risk zones. Councils with a higher proportion of designated land tend to issue earlier deadlines and run them longer.

Vegetation curing rates. Curing is the percentage of dead, dry fuel in a grass paddock. Hills councils with eucalypt forest cure later than coastal sand-plain heathland, so the Perth Hills shires often allow maintenance to end in March while coastal Peel councils run through May.

Local fire history and risk modelling. Councils that have run prosecutions or had recent escape fires from non-compliant blocks (Wooroloo 2021 sits in this memory for the Perth Hills) often tighten dates and lift fines.

The result is a patchwork where two neighbouring properties on opposite sides of a council boundary can face different start dates, sometimes weeks apart. That is the single most common way people get caught out after moving.

How to find your exact deadline

Three ways, fastest first:

1. Use the firebreak deadline lookup. Enter your address and the tool resolves your council and shows your current-year dates.
2. Go to your council's website and search for "firebreak notice" or "fuel hazard reduction notice". The notice is usually a PDF gazetted under section 33. Every council page on firebreakcheck links to the official notice.
3. Phone your council ranger. Ranger services teams are the people who write and enforce the notice. They will tell you the dates, the width, and the height rules over the phone. Identify yourself by property lot number so they can confirm whether your block sits inside a bushfire-prone area.

If your property straddles two councils (rare but it happens on rural blocks), you must comply with both notices on the relevant portions of the block.

What "maintain" means - it is not one-and-done

This is the single most common point landholders miss. The notice does not say "clear once by 1 November". It says "install by [date] and maintain through to [date]". Practically that means:

• Grass regrowth. If your slashed break has grown back above 50 mm by Christmas, you are no longer compliant. A ranger inspection between November and the maintain-until date will issue against the state of the break on the day they visit, not its state on installation day.
• Wind-blown leaf litter. Eucalypts shed bark and leaves through summer. A mineral-earth break under a treeline needs raking back during the season.
• Asset Protection Zones. If your block carries an APZ around buildings, the maintain rule applies to the APZ too - it is not a "clear once in spring" job. See Asset Protection Zones in WA explained.
• Boundary changes. If you fell a tree or build a shed during the season that brings new fuel inside the break, your compliance resets and you must re-clear.

The maintenance burden is why most landholders with anything over an acre book a seasonal maintenance contract rather than a one-off slash. See ongoing maintenance and how to choose a firebreak contractor in WA.

What happens after the maintain-until date

After the final maintenance date in your council's notice (30 April for most metro councils, mid-May for Peel and South-West), the formal Firebreak Notice obligation lapses for the year. Three things still matter:

1. The Restricted Burning Period and Prohibited Burning Period dates are separate and run on their own DFES-set calendar. You may still be inside a burning ban even after firebreak season ends. Check the DFES burning period dates for your district.
2. Permits for autumn pile burns of cleared material are typically only available outside the Prohibited Burning Period and require a permit from your local Bush Fire Control Officer.
3. Next season's deadline. Some councils' notices are gazetted as standing instruments and renew automatically. Others publish a fresh notice each year. We track this and update each council page in September-October as new notices land.

A note on regional and Wheatbelt councils

The deadlines above lean metro/peri-urban / South-West. If you are on a Wheatbelt or pastoral block, your council's deadline can be earlier - the Shire of Cunderdin's 20 September deadline is one of the earliest in the state, reflecting late-spring cropping and harvest fire risk. Cropping farms generally face additional rules around stubble retention and header firebreaks that are not covered in detail here. The Shire of Tammin, Quairading, Pingelly and Beverley pages list the local specifics.

FAQ

Are firebreak dates the same every year? The structure stays the same most years, but exact dates can move when a council updates its notice. Always check the current-year notice on your council's website before booking work. Every firebreakcheck council page links to the current notice and stamps the date we last checked it.

My block is under half a hectare. Do I still need a firebreak? Most council notices set a minimum block size below which only an Asset Protection Zone or perimeter clearance applies, not full firebreaks. The threshold is commonly 0.2 ha or 0.5 ha. Read your council's notice - the City of Swan and City of Wanneroo notices both list block-size triggers.

Do I have to do the work myself? No. You can hire a contractor. The legal obligation sits with the owner / occupier of the land regardless of who does the work. See how to choose a firebreak contractor in WA.

What if I am buying a property mid-season? Compliance transfers with title. The new owner is responsible for the firebreak from settlement. Some buyers add a settlement-condition clause requiring vendor compliance with the current notice. Talk to your settlement agent.

What about rented properties? The Bush Fires Act notice is issued to "the owner or occupier". In a residential tenancy, this is normally the landlord. Your lease should be explicit. If a ranger issues an infringement, who pays is between you, your tenant, and the council.

Can my contractor get the council deadline extended? No. The deadline sits with the landholder under the council notice. A contractor can only do the work. Book early - October is too late on Hills blocks, especially if you also need green-waste removal.

The maintain-until date is not the same as the burning ban end date. Why? Two different regulators. Firebreak deadlines are set by your local government under the Bush Fires Act s.33. Burning ban dates are set by DFES on a district basis. They overlap but are not identical.
