3.0 Bushfire Risk Mitigation Measures
The following section describes Bushfire Risk Mitigation measures, recommended to be
utilised at the subject site to reduce the risk of Bushfire impacting on people and property.
The scope of proposed Bushfire Risk Mitigation Measures have been drawn from the
following sources:
     ▪   the Queensland State Government Single State Planning Policy - Part E (SPP 2017);
     ▪   the Bushfire Resilient Communities Technical Reference Guide (QFES,2019);
     ▪   the Noosa Plan 2017, Division 9 – Natural Hazards Overlays Code; and
     ▪   the Australian Standard (AS 3959- 2018) - Construction of buildings in bushfire prone
         areas.
The intent of the above legislation is to protect people and premises in the event of a bushfire
emergency, through achieving acceptable Performance Outcomes for the development given
the identified bushfire hazard. Performance Outcomes are generally achieved by appropriate
separation of a development from bushfire hazard, appropriate access for fire-fighting
vehicles, and appropriate construction standards of buildings. Additional factors are detailed
where considered appropriate.

3.1 Asset Protection Zones
Asset protection zones (APZ’s) provide a defensive tool to assist in the reduction of potential
bushfire impact to people and property situated in bushfire prone areas. APZ’s are the most
strategically valuable defence against radiant heat and flame, and to a lesser extent, embers.
Whilst APZ’s should prevent buildings from being subjected to direct contact from flames, and
reduced levels of radiant heat in the event of a bushfire, building construction standards will
also be key to ensuring the performance of buildings subjected to ember attack. Bushfire
Attack Level for the proposed development is determined in Section 3.2.
Based on the above Bushfire Hazard Assessment, APZ’s may be required adjacent the
proposed development. These are detailed in the following section.

3.1.1 Performance Outcomes
APZ and setback distances have not been prescribed in the SPP 2017. The SPP refers to
‘provision of appropriate defendable space between dwellings and medium or above Bushfire
Hazard’. The Bushfire Resilient Communities Technical Reference Guide (QFES, 2019), refers
to determining APZ’s based on achieving a maximum 29kW/m2 radiant heat flux exposure.
This is achieved by using either the Method 2 Bushfire Attack Level Assessment as per the
AS3959,2018 for Construction of Buildings in Bushfire Prone Areas or Bushfire Asset Protection
Zone Width Calculator (QFES, 2019), which uses the calculations underpinned by the AS3959,
2018 calculation.
