Greg Mullins AO AFSM became a major national figure in the 2019–20 bushfire crisis – Australia’s longest, hottest and most devastating on record. From being a volunteer firefighter then a career firefighter, he is an internationally recognised expert in responding to major bushfires and natural disasters. During his 39-year career he served as President, Vice President and Board Chair of the Australasian Fire & Emergency Service Authorities’ Council, Deputy Chair of the NSW State Emergency Management Committee, Australian Director of the International Fire Chiefs Association of Asia, NSW representative on the Australian Emergency Management Committee, Australian representative on the UN’s International Search & Rescue Advisory Group, and as a member of the NSW Bushfire Coordinating Committee. He is currently Chair of the NSW Ambulance Service Advisory Board. In early 2019 he formed Emergency Leaders for Climate Action, a coalition of 34 former fire and emergency service chiefs from throughout Australia. They tried to warn the federal government of an impending bushfire disaster, were ignored, but continue to explain how climate change is super-charging the bushfire problem and why urgent action is needed on greenhouse emissions.
