Disaster management in Australia: the national emergency management system.

Australia has a well-established emergency management system to manage the threats to communities from natural and technological hazards. The key elements of the system are described with particular emphasis on the impact of disasters on Australia, fundamental concepts, and principles of planning. Emergency physicians have a key role in the development of emergency plans and in the overall health response to disasters. They can enhance their understanding of local, State and national arrangements by participating in exercises and appropriate disaster medicine and emergency management courses.
