Emergency Management Australia (EMA) is a division of the federal government Department of Home Affairs. EMA leads the Australian government’s disaster and emergency management response.   EMA will coordinate emergency response efforts if any emergency exceeds the ability of individual jurisdictions to respond effectively.  EMA works with all state and territory governments to ensure effective planning and response to emergencies.  They also provide financial assistance to individuals and communities affected by a natural disaster.  This site provides information about how the system of government support works.
