The country's Bureau of Meteorology said more than half of Australia was in the grips of extreme heat, especially South Australia and Victoria, with temperatures forecast to reach up to 47C in inland areas.
Firefighters were grappling with blazes in several areas of Victoria on Thursday and a number of towns near Seymour were evacuated as responders struggled to contain outbreaks. A segment of the Hume Highway, the main road between Melbourne and Sydney, was also closed due to fire threats.
Friday "is going to be the peak fire danger day, especially for Victoria", said Sarah Scully, a meteorologist at the Bureau.
High temperatures, strong gusty winds and "dry lightning", where thunder storms had little rain, all increased the risk of fires, she added.
