The record heat combined with drought conditions is contributing to massive bushfires. Many areas have total fire bans and New South Wales has declared a state of emergency through next week. Because of the bushfires and smoke, numerous areas in Australia are reporting unhealthy or hazardous air quality, with 2 areas reporting hazardous air with an AQI over 1000. https://aqicn.org/map/australia/
