6.4       Potential Impact Buffer
As analysis of heat radiation decay curves and national research indicating that in most fires over
80% of housing loss and 80% of human life loss has occurred within 100m of bushland (Leonard et
al., 2014, page 7) specify that a default 100 meter buffer from the edge of hazardous vegetation
which has a Medium, High or Very High Potential Bushfire Intensity Class. The areas of Medium,
High or Very High Potential Bushfire Intensity Class and Medium, High or Very High Potential
Bushfire Intensity Class Buffer are shown on the map on the next page.

6.5       Map of Potential Bushfire Impact classes and class buffers.
The map below shows the areas of the Potential Bushfire Impact classes and class buffers. The
location of the house is in an area assessed as Potential Bushfire Impact Buffer Class.

that all of the the house in an area assessed as Potential Bushfire
Impact Buffer Class.

6.6       Assessment of bushfire Prone Area
The assessment of Potential Bushfire Impact Buffer Class confirms that:
      •    The location of the house is deemed to be in a Bushfire Prone Area.
As the house is in a Bushfire Prone Area, an assessment of the Bushfire Attack Level using the
protocol of Australian Standard AS3959 Construction of buildings in bushfire prone areas is
required to be conducted as specified by the Queensland Building Act and the bushfire
requirements of the National Construction Code.
Such a Bushfire Attack Level assessment is conducted on subsequent pages of this report.
