Photo of a bushfire. All Class 1 buildings located in a designated bushfire prone area are to be constructed in accordance with the requirements of AS 3959 Construction of buildings in bushfire prone areas. There may be state or territory variations as indicated in the BCA.

AS 3959 provides a method of assessing the bushfire risk of a site by categorising the terrain including the slope and type of vegetation present. The categories of bushfire attack are:

  • low
  • medium
  • high
  • extreme.

Note that buildings within the low category of risk require no special construction techniques.
