Australia recorded its hottest month ever in January, with average temperatures exceeding 30C (86F) for the first time.
According to the Bureau of Meteorology, the extreme heat was "unprecedented" during the country's summer period.
At least five January days were among the 10 warmest on record, with daily national temperature highs of 40C.
The heat has caused wildfire deaths, bushfires and a rise in hospital admissions.
Several wildlife species have also suffered, with reports of mass deaths of wild horses, native bats and fish in drought-affected areas.
The new record surpasses conditions recorded in 2013, previously considered the nation's worst heatwave.
