Bushfire Ratings

Many people dream of living within reasonably close to the city while still enjoying bushland surrounds. But this dream comes with serious risks and you need to understand the correct Bushfire Attack Level (BAL) for your new home’s construction or renovation. BAL ratings dictate both the construction method and the materials used in bushfire prone areas and can be obtained from your local council. There are six BAL ratings (low through to extreme), and councils are required to map bushfire prone land and categorise it using the BAL rating system.

BAL LOW
Insufficient risk to warrant specific construction requirements.

BAL12.5
Ember attack.

BAL19
Increasing levels of ember attack and burning debris ignited by windborne embers, together with increased heat flux between 12.5 and 19kW/m².

BAL40
Increasing levels of ember attack and burning debris ignited by windbore embers together with increased likelihood of exposure to flames and increasing heat flux between 29 and 40kW/m².

BAL FZ
Direct exposure to flames from fire front in addition to ember attack and heat flux greater than 40kW/m².
