The site is contiguous with hazardous vegetation to the west (i.e. based on the results of
the above hazard assessment completed in accordance with the SPP 1/03 Guideline),
and although this vegetation occurs in a low-lying area and was partially inundated
during the site inspection, it was considered that during extended drought periods this
vegetation may pose a bushfire risk to the site.

Based on the above, it is considered that although the Noosa Plan (2006) bushfire hazard
mapping assigns a Moderate bushfire hazard to a portion of the site, the site specific
hazard assessment completed in accordance with the SPP 1/03 Guideline determined
that vegetation within Noosa National Park to the immediate west of the site also has a
Moderate Bushfire Hazard rating, and there is a risk that a severe bushfire impacting on the
site.

Quantitative modelling has therefore been completed below to determine the potential
impacts of a bushfire in the event of a fire head impacting on the site from hazardous
vegetation to the west.

4.4      Quantitative Risk Modelling
4.4.1      Background
Modelling of the potential bushfire conditions that may be experienced at the subject site
was undertaken. The models used comprise industry standard bushfire equations.
Modelled scenarios comprised bushfire encroachment through existing vegetation from
the west towards the site.

This modelling objectively calculates and determines the potential nature and severity of
bushfire attack more thoroughly than described by SPP 1/03 above and serves as a basis
for determining the construction and other bushfire protection measures detailed in the
Bushfire Management Plan (Section 5.0).

4.4.2      Site Specific Input Parameters
The modelling utilises the slope and aspect parameters collected during the SPP 1/03
assessment above combined with a Fire Danger Index1 for the Sunshine Coast region
sourced from the Australian Standard AS 3959- 2009 - Construction of buildings in bushfire
prone areas, and potential fuel loads derived from Leonard et al. (2014).

The following industry standard bushfire equations were utilised:




1 The Australian Standard AS3959: 2009 defines Fire Danger Index as the chance of a fire starting, its rate of
spread, its intensity and the difficulty of its suppression, according to various combinations of air temperature,
relative humidity, wind speed and both the long and short term drought effects.
