Bushfire Zones are areas of land that are prone or subject to bushfires.
Bushfire Zones are mapped out by the Queensland Government using a state-wide mapping methodology that takes into consideration landscape slopes, vegetation hazard classes, varying weather conditions, grassfire prone areas and many more factors, to determine the different Bushfire Zones and Bushfire attack levels (BAL).
Bushfire Attack Levels
There are varying degrees of bushfire hazard zones and they are categorised by a BAL. These range from BAL-Low, which is the lowest level hazard, up to BAL – FZ (Flame Zone), being the highest.
BAL-LOW (very low risk)
BAL-12.5 (low risk)
BAL-19 (moderate risk)
BAL-29 (high risk)
BAL-40 (very high risk)
BAL-FZ [Flame Zone] (Extreme Risk)
These zones aim to improve the impact of bushfires on homes in these areas. Homes in bushfire zones require specific construction standards for new dwellings.
If you're planning to build in a Bushfire Hazard Zone, the first thing you need to consider is how high the BAL is. The varying BAL classifications come with varying construction requirements, which should be taken into consideration when designing your home.
These construction requirements can have an impact on materials such as windows, doors, flyscreens, external wall materials etc., and can also impact external landscaping and structures.
