Bushfire zone requirements

Australian Standard AS3959-2018 ‘Construction of buildings in bushfire-prone areas’ includes a method for assessing categories of bushfire attacks called Bushfire Attack Levels (BAL) in areas that have been classified by authorities as being ‘bushfire prone’.

It also provides construction and building material provisions for the use in buildings to resist bushfire attacks resulting from burning embers, radiant heat, flame contact and combinations of the three.

A building certifier or surveyor will use the designated BAL rating to check compliance with the construction requirements of the standard and / or any other local legislative requirements. It is the responsibility of the building designer to ensure compliance to AS 3959 and / or any other local legislative requirements are met in accordance with the requirements of the National Construction Code (NCC) 2022.
