<strong>Bushfires</strong> 25<br />

An alternative method outlined by Raymond is the creation of permanent breaks or fuel<br />

reduced zones behind properties. Whilst recognising that this was not a new idea in bushfire<br />

mitigation, Raymond noted the need for a more strategic and formalised approach through<br />

the Bushfire Risk Management Planning process. The areas could be maintained on a yearly<br />

or two yearly cycle through the land management authority or preferably, jointly with a<br />

community fireguard program, so that both property occupier and land manager are working<br />

towards the same goal.<br />

Raymond argued that the other part of a strategy to protect life and property was<br />

operational management. The increased use of aircraft has assisted in fire suppression<br />

activities within the Sydney region. He argued that the infrastructure for fire suppression,<br />

principally aircraft, need to be pre-planned and in place before the fire season. This includes<br />

helipads, water points, marking of power lines, and strategy plans in place before unplanned<br />

fire events occur. In areas away from the ocean, alternative water sources need to be<br />

developed. This includes water storage tanks for helicopter use, permanent or temporary<br />

fixed wing bases for easy access and quick set up. 61<br />

Earlier in this Paper reference was made of the work of Pyne, who noted the development<br />

of the ‘Australian strategy’ of broadscale hazard reduction burning. It is evident that this<br />

approach is no longer of relevance. The current practice in regards to prescribed burning<br />

is not one of broadscale burning but one of ‘mosaic burning’. For instance, in the<br />

preparation of fire management plans Rose et al recognise a mosaic level at four spatial<br />

levels: regional; management zone; vegetation community; and burn patch. A strategic<br />

mosaic is developed based on the following factors: an analysis of fire behaviour potential;<br />

fire regime threshold guidelines for broad vegetation communities; location and vulnerability<br />

of community assets and fire sensitive ecological/environmental features; and naturally<br />

occurring fire mitigation factors and fire suppression options. 62<br />

In evidence before the NSW Legislative Council Committee Inquiry into the Rural Fire<br />

Service, the Director of the National Parks and Wildlife Service noted the following about<br />

hazard reduction:<br />

In recent times, we have become more sophisticated in our capacity to control hazard<br />

reduction burns, we are actually managing strategic burns at the interface where there is<br />

the greatest risk of the fire moving off the park and where we need to manage that<br />

interface in order to protect life and property and be a good neighbour. We are refining<br />

bushfires on the urban interface of Sydney.” in Australian Bushfire Conference, Albury July<br />
