Although the costs of bushfires in Australia are relatively lower than those for other natural hazards, they lead to the highest rates of death (BTE, 2001). There is also a trend for increased levels of building in bushfire prone areas (AFAC, 2001). This paper addresses some basic questions about communities that are vulnerable to bushfire hazard in Australia: where are these communities located, what do they look like, what do we know about the people who live there and what are the implications for bushfire mitigation?

In Australia, the fire hazard to peripheral areas of Sydney, Melbourne, Hobart, Brisbane, Perth, Adelaide and, more recently, Canberra, are those which gain the most attention because of the numbers of people affected, the numbers of deaths, the costs of property damage, the problems associated with mitigation and response and the rapid changes in population at these locations. 3.

Abstract

The issue of communities and their exposure to bushfire hazard is highly topical internationally. There is a perceived trend of greater
exposure to bushfire risk which is exacerbated by increased levels of building in fire-prone areas or peri-urban regions. There is a need to
clarify what we understand to be peri-urban regions, and how we conceptualise and describe the communities that reside in them, in
order that efficient and effective services are provided. However, more questions arise for us. For example: Where are these communities
located? What do we know about the people who live there? What are the implications for bushfire mitigation? Despite being
problematic, locality remains important to the understanding of communities, bushfire hazard and delivery of services.
