In Victoria, any new residential building will be measured on a Bushfire Attack Level (BAL). The BAL measures a building's potential exposure to ember attacks, radiant heat and direct flame. Any land with a BAL rating of 12.5 or above will require bushfire construction compliance, with the rating dictating the method of construction and materials used. BAL ratings can significantly increase the cost of your build.
The Bushfire Attack Level ratings are:
- BAL-FZ (Flame Zone)
