Bushfire

Redland City has a significant coverage of very high to high bushfire prone areas across its mainland region, stretching from Venman National Park at Mount Cotton north to Capalaba and south east to Redland Bay. Bushfire hazard mapping for each suburb of Redland City can be found within the suburb information on this website. It is based on state-wide Bushfire Hazard Area maps that have been prepared to support implementation of a single State Planning Policy released by the Department of State Development, Infrastructure and Planning. The State Planning Policy interactive mapping system can be accessed via the following link: www.dsdip.qld.gov.au/about-planning/spp-mapping-online-system.html

Bushfire vulnerability on the Moreton Islands

Coochiemudlo, Macleay, Lamb and Karragarra Islands have small patches of remnant bushland which are not considered significant enough to allow a fire to develop to a point where it is likely to become uncontrollable. Hazard reduction burning and maintenance of fire lines by Redland City Council is helping to mitigate the impacts of unplanned fires to the community and the environment. Russell Island has a higher risk of being adversely impacted by bushfire with swamp land across large areas of the island being highly combustible and mainly inaccessible, limiting the capacity to implement mitigation measures. Given the appropriate conditions this could result in fast moving, intense fires. Therefore, the majority of fire fighting activities undertaken on Russell Island would concentrate on protection of life and property.

North Stradbroke Island has the greatest risk of bushfire amongst the Islands of Moreton Bay. The majority of the island is identified as having a medium to high bushfire risk on current mapping. Various government agencies undertake hazard reduction burns and maintain fire lines to reduce the impacts of unplanned fires; however the inaccessibility of large areas of the island’s interior limits the extent to which hazard reduction burning can be undertaken. Communities at greatest risk on North Stradbroke Island include: the elevated areas at round Rainbow and Illawong Crescents at Dunwich, the One Mile and Two Mile communities, Amity Point and the Flinders Beach community, the elevated areas of Point Lookout around Tramican and Donahue Streets, and George Nothling Drive east to Samarinda Way. The beach camping sites along Flinders Beach and Main Beach are also vulnerable to bushfire and have the added problems of limited access and no mains water supply. Bushfire hazard mapping for the Islands of Moreton Bay is provided for each of the islands in Parts 5-10 of this plan.

Building in Bushfire Prone Areas

The Bushfire Prone Area is defined as land that could potentially support a bushfire or land that could be subject to significant bushfire attack. The Bushfire Prone Area is therefore made up of two components – land of very high intensity, high intensity or moderate intensity Potential Bushfire Hazard (i.e. land that could support a bushfire) and Bushfire Defence Areas (i.e. land that could be subject to significant bushfire attack). The default width of the Bushfire Defence Area is 100m from areas of very high intensity, high intensity or moderate intensity Potential Bushfire Hazard.

In developing the bushfire hazard mapping, consideration is given to the factors that influence bushfire behaviour (such as fire weather severity, topography and vegetation) and the impact of bushfire events on urban areas and communities. The community’s behaviour before, during and after bushfire attack also influences the overall impacts and vulnerability of a community. Climate change also provides a new challenge in anticipating how bushfire behaviour and impacts will change in the future.

Queensland has adopted the Australian Standard for the Construction of Buildings in Bushfire Prone Areas – AS3959 – 2009. AS3959 sets out the requirements for the construction of buildings in bushfire prone areas in order to improve their safety when they are subjected to burning debris, radiant heat or flame contact generated from a bushfire. There is no one answer for protecting buildings against fire attack, rather a combination of methods is the best defence. These include, but are not limited to:

  • The correct siting of buildings
  • Creating barriers and buffer zones around your home
  • Using the appropriate design and construction methods and materials for new residential buildings.

You should check with Redland City Council to determine if your property is in a “bushfire prone area”.
