5.5    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.
