5.2       Numbers of people likely to be present

Up to 3 - 5 residents including children 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 10. State Government revised FDI values to FDI 50 for the area involved. (CSIRO, 2014).


6.2       Anticipated direction of bushfire attack

The potential directions of attack are shown in Figure 4. The probability of attack at some time is regarded as
likely, with the hazard partially aligned with the direction of worst case fire weather conditions for the region,
these being westerly to north westerly.

Section 6.3 models the scenario of fire occurring under FDI 50 conditions.
