Bushfire warnings have been put in place for NSW, Victoria, Tasmania and South Australia as the Bureau of Meteorology warned of severe heatwave conditions this weekend.
NSW: Take care
NSW residents are being told to prepare for a scorcher of a weekend, with warnings to drink plenty of water and to take care in the surf, and prepare properties for the increased bushfire danger.
The Bureau of Meteorology has warned of severe heatwave conditions for much of the state across the weekend with the mercury expected to peak on Sunday.
Parts of NSW are tipped to reach 45C on Saturday including Menindee in the far west and Ivanhoe in the state's centre.
Victoria: Stay inside
Victorians have been told to stay inside as parts of the state brace for the hottest day in nearly two years.
Melbourne and Geelong are forecast to reach 42C on Saturday, with winds of up to 40km/h.
Bendigo, Echuca and Avalon are set to climb to 43C, while Mildura and Warracknabeal could soar to 45C.
"This heat is a killer. It's going to be like a blast furnace tomorrow and you need to adjust what you do," Ambulance Victoria's state health commander Paul Holman told reporters on Friday.
