More than 200 extreme weather records have been broken in Australia this summer in what the Climate Council says was the hottest on record.
The council will release a report on Thursday highlighting the temperature extremes marked over the past three months.
The Climate Council says 206 weather records were broken in 90 days around Australia.
"This summer was so hot we witnessed fruit cooking on trees," Climate Council chief executive Amanda McKenzie said.
The council's report says the record-breaking summer was driven by greenhouse gas pollution from the burning of fossil fuels and land clearing.
"Now, hot on the heels of Australia's 'angriest summer', we have autumn fires burning across parts of Victoria," former NSW Fire and Rescue Commissioner Greg Mullins said.
"Climate change has lengthened bushfire seasons.
"In Victoria, the fire season started early. This has put a great deal of pressure on firefighters; we simply don't have the resources for this new reality."
