Heatwave responses, from public education to formal heat-warning systems, are the best-developed element of adaptation planning for health in Australia, but many metropolitan centres are still not covered  . Air conditioning  in Australian homes reduces mortality in heatwaves by up to 80% , but heavy reliance on AC carries risks. It is estimated that a power outage on the third day of extreme heatwaves would result in an additional 10-21 deaths in Adelaide, 24-47 in Melbourne and 7-13 in Brisbane . Multiple interventions at the landscape, building and individual scale are available to reduce the negative health effects of extreme heat .
