Building or buying in a bushfire-prone area? Have you tried our new BAL Estimator?
We've built a free BAL Estimator to give you a fast, planning-stage indication based on AS 3959 Method 1.
It takes less than a minute:
🌳 Select the vegetation closest to your site
đź“Ź Enter the distance to that vegetation
⛰️ Add the effective slope (there's a built-in rise/run calculator if you're not sure of the angle)
You'll get an indicative BAL rating plus the construction tier and radiant heat flux that comes with it. Enough to budget early and know what questions to ask your builder, designer, or certifier.
Whether you're an owner-builder, buying a block, or a builder scoping a job, it's a smart first step before commissioning a certified assessment.

Note: this is a planning-stage estimate only. A certified BAL assessment still requires an on-site inspection by an accredited bushfire practitioner. That's where our BPAD-accredited team comes in.
