1.6      Fire Weather

The fire season in South East Queensland is typically from August to November. This is the dry season for SEQ. Strong
westerly winds can accompany bushfire weather during this period. Westerly winds are typically drier winds and
accompany low humidity. In this regard winds from this direction are typically regarded as bushfire winds, though
bushfires will spread under the influence of any wind regardless of its direction where there is fuel to enable its continued
combustion. Fire behaviour and therefore bushfire risk is heavily influenced by weather conditions. Fire weather in
Queensland is typically much less severe than in southern states.


1.7      Fire Run

The length of fire run influences the area in which a fire has to develop and reach its potential maximum intensity for the
conditions at the time of the fire. In this regard it is important to assess the length of fire run to grasp an understanding of
the scale of fires that may be able to eventuate in the area. Fire runs less than a 1km in length may be safely regarded
as having a lesser risk than longer fire runs.


Fire runs may be modified by natural features such as creeks, swampy wet areas, rock formation or wet vegetation
types. They may also be limited by roads, firebreaks or active intervention of fire suppression techniques such as lighting
of backing fires from control lines.


The fire runs in the National Park adjoining the site range from moderate (approx 850m) to large several kilometres to the
south. Fires runs to the west are typically in the vicinity of 1km. The National Park contains several fire trails from which
the fire run may be reduced. Burgess Creek also flows centrally through the adjoining section of park and except for
under high to extreme fire weather conditions would help limit the extent of fire spread.


Fire runs are shown on map 3.
