Appendix F - bushfire attack level assessment report · MCU25/0022

5.0 Specific risk factors associated with the development
proposal
5.1      Nature of activities anticipated on site

Normal residential activities are anticipated to occur in the area. The number of fire incidents expected by
QFES varies in direct proportion to the numbers of people present. The proposed development does not add
significantly to the number of people living in the area or likely to cause ignition.

5.2      Numbers of people likely to be present

Up to 1 - 2 residents are generally expected to be present on the Subject Lot, depending on time of day and
timing of holidays. The proposed development does not add significantly to the number of people living in the
area or potentially exposed to the small possibility of unplanned fire.


6.0 Nature and Severity of Potential Bushfire Attack
6.1      Bushfire season and Fire Weather

The “typical fire season” in this area peaks between September and November. The predominant winds in
the area are south easterly, however during the fire season, hot gusty westerlies of over 30 kph can be
expected, with Relative Humidity falling to 15% and less. Temperatures on these days can climb over 35⁰C ,
and for two or three days a year, fire weather conditions equivalent to FDI levels of around 50 can be
anticipated. (Note that this is in contrast to the value of 40 which Queensland is currently using in the
recently revised AS3959 - 2018).




Figure 7. State Government revised FDI values to FDI 46 for the area involved. (QFES Catalyst, 2023).
