Fire management and fire-break preparation on acreage properties

Your obligations under Queensland law

Under the Fire and Emergency Services Act 1990, landowners must take reasonable steps to prevent fire on their property spreading to neighbouring land. This includes maintaining firebreaks, managing vegetation, and ensuring access for firefighting purposes.

Brisbane City Council has specific vegetation management requirements for acreage properties. Ipswich City Council has its own local fire laws prescribing minimum firebreak widths and vegetation height limits. Check your local council requirements annually — these can and do change.

What is a firebreak?

A firebreak is a strip of land cleared of combustible vegetation, typically positioned around property boundaries and along internal access tracks. Its purpose is to slow or stop the spread of fire across the landscape.

Standard firebreak specifications typically require: a minimum width of 3 to 6 metres (verify with your local council), vegetation kept below 10 centimetres, and clear access for firefighting vehicles.

How vegetation management reduces fire risk

The primary risk factor in a grass fire is fuel load: the volume of dry, cured vegetation available to burn. Regular slashing and mowing reduces fuel load directly. A property mowed to 10 centimetres in September presents a very different fire risk to a property with 60 centimetres of dry signal grass or Guinea grass.

Timing matters. The optimal window for fire-break slashing in the western Brisbane suburbs is August to early September — after winter growth has cured but before the onset of the fire weather that peaks in late September and October.

Practical steps

• Establish a perimeter break around the property boundary — minimum 3 metres wide, clear to the ground
• Slash internal tracks and access routes to the same standard
• Keep the area around any structures clear of vegetation for a minimum of 20 metres where possible
• Don't burn off without a fire permit — open burning is regulated and seasonal restrictions apply
• Check the Queensland Rural Fire Service hazard reduction permit requirements before any burning
