Communities and bushﬁre hazard in Australia:
More questions than answers

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.
