      Whilst an assessment of vegetation types, fuel loads, effective slope and other factors can be readily
      undertaken, fire weather can fluctuate across days, weeks and seasons and can have a significant
      impact on the potential for bushfire threat, as well as influence bushfire behaviour and intensity. The
      Forest Fire Danger Index (FFDI) is a commonly used method to readily advise the community of the
      likely ability of fire suppression based on fire weather, which is used to inform the Fire Danger Rating
      (FDR) System (Figure 8). It is important to maintain awareness as to the level of local fire danger
      during the fire season.

5. BUSHFIRE HAZARD ASSESSMENT
  The State Government Single State Planning Policy (SPP) released in 2017, includes mapping that is an
  outcome of the new bushfire hazard mapping methodology, developed by the CSIRO and the Queensland
  Government. The new Bushfire Prone Area mapping was found to have an average reliability of 85%.
  The new methodology provides a major improvement in bushfire hazard mapping.

  The new modified approach calculates potential fire line intensity using total fuel loads, landscape slope
  and fire weather severity. A default 100-metre buffer was determined from analysis of heat and radiation
  decay curves and research that indicates 80% of housing loss and 80% of life loss occurred within 100
  metres of bushland.

  The subject site is identified on the State Planning Policy Natural Hazards Risk and Resilience mapping
  Hazard Overlay as being within the n high and very high hazard zone, requiring the bushfire hazard
  impacts be addressed (Figure 9).
