How to Tell If Your Firebreak Meets WA Standards

A Simple Guide for Perth Property Owners

Firebreak compliance can be confusing, especially when each council has slightly different requirements. But the good news is, there are some clear signs that show whether your firebreak is ready for inspection.
Here’s a quick guide to help you check your property before council inspectors arrive.

1. Check the Deadline

In most parts of Perth, firebreaks must be installed by 30 November and maintained until 31 March.
Some councils, such as the City of Swan and Shire of Mundaring, require firebreaks to be in place earlier, by 1 November.
If you’re unsure, check your council’s annual Firebreak Notice or contact Green Surgery for advice.

2. Measure the Width

Firebreaks across Western Australia generally need to be at least 3 metres wide, cleared right down to bare earth.
If your property is larger or located in a high-risk area, you may need wider or multiple firebreaks.
Tip: walk the boundary and measure at regular points to make sure the full strip is clear and consistent.

3. Check for Vertical Clearance

Firebreaks also need to be safe for fire trucks to access.
Make sure there’s at least 4 metres of vertical clearance above the cleared strip — that means no low-hanging branches, shrubs, or obstructions overhead.

4. Remove Flammable Materials

A compliant firebreak should be completely free of anything that can burn.
That includes:

• Dry grass or weeds

• Piles of leaves or mulch

• Branches, twigs and bark

• Stored wood or debris

If you can see patches of long grass or loose material, it’s time to clear or slash again. Green Surgery’s slashing team can handle large blocks or heavy vegetation safely.

5. Check for Continuous Access

Your firebreak should form a continuous loop inside your property boundary, without dead ends or obstacles.
Driveways, gates or fences must allow emergency vehicles to access all areas easily.
If there are narrow pinch points, tree roots, or eroded sections, consider re-grading those areas before inspection.

6. Maintain It Regularly

Firebreaks aren’t a once-a-year job.
Dry winds and regrowth can quickly undo your hard work. Regular maintenance throughout summer keeps you compliant and reduces bushfire risk.
Our firebreak contractors offer scheduled maintenance programs for Perth’s northern suburbs.

7. Keep Records and Take Photos

Before inspection season, take photos of your cleared firebreaks and store them with the date.
If there’s ever a dispute or council query, this evidence can help demonstrate compliance.
We also provide compliance reports and certificates upon request.

Common Signs of Non-Compliance

If you notice any of the following, your firebreak may fail inspection:

• Overgrown grass or weeds

• Tree branches hanging into the cleared area

• Firebreaks not connected around the full boundary

• Debris piles, stumps or leaf litter within the zone

• Bare-earth strip less than 3 metres wide

If in doubt, it’s safer to call the professionals. Councils can issue fines between $250 and $500, or up to $5,000 for serious breaches.
