Bushfire Attack Level

If you are building or extending a dwelling or other accomodation in a designated Bushfire Prone Area by more than 50%, you will need a Bushfire Attack Level (BAL) assessment and report. 'Specific Use Bushfire Protected Buildings' such as healthcare, aged care and education facilities also require a BAL.

​A BAL is a means of measuring the severity of a building's potential exposure to ember attack, radiant heat and direct flame contact. There are 6 levels which determine the minimum construction standards outlined in AS 3959-2018 according to bushfire attack. These levels range from BAL-LOW to BAL-FZ (Flame Zone). ​
An increase in BAL rating will add significant costs to your build. We can assess your site and identify the applicable BAL for your development.
What we do - 
  • Conduct a detailed site assessment;
  • Assess the property and its surrounding landscape in accordance with AS 3959-2018 Construction of buildings in bushfire-prone areas. 
  • Analyse the bushfire risk to the proposed development using Method 1 of AS 3959-2018, or Method 2 for more complex sites.
What you get - 
  • A BAL report (with options for lowering the BAL if appropriate).

Size of development -
We can provide you with a BAL report if you are looking to:
  • Build a single dwelling; 
  • Extend an existing dwelling;
  • Build a shed, carport or deck; or
  • Plan a multi dwelling development. 
How long it will take - 
  • In most cases we can do the site assessment and email the BAL report to you within 5-10 working days.
