Counterdisaster planning for mass fatalities begins with an analysis of the types of disasters likely in a given area and the vulnerability of the area to those disasters. Mass-fatality disasters can be classified as man-made or natural. A historical list of the major man-made disasters in Australia is provided. Potential natural, disasters in Australia, such as bush fires, floods, cyclones, and earthquakes, are discussed. The Australian Bureau of Meteorology provides warnings in many of these situations. Counterdisaster planning in Australia is primarily a state responsibility. The Natural Disasters Organisation of the Federal Department of Defence operates an Australian Counter-Disaster College.
