A severe heatwave is expected to impact three states heading into the new year break.
Parts of Queensland, the Northern Territory and Western Australia have been put on alert with conditions 8C to 12C above average.
On Saturday, the mercury is set to reach a stifling 49C at Marble Bar in the west's Pilbara region, with 45C predicted over the next six days.
An extreme fire danger warning was issued for the Burrup region in the state's northwest on Saturday morning.
Uncomfortably warm nights are likely to set in across the Northern Territory with Tennant Creek, 500km north of Alice Springs, set to reach 43C while in Katherine it's likely to get to 40C.
There's no reprieve for storm-ravaged areas of Queensland either, with Longreach expected to reach 47C, Wilson tipped to hit 43C and 37C in Gympie.
One resident of the Gold Coast Hinterland told AAP her family had been struggling through the heatwave conditions without power, water or phone reception after Christmas day storms ravaged the area.
"We've been trying to avoid being at home because it's so hot," Nicole Fraser-Lyons said.
"When you're at home you're sweating to death and thinking 'when is the power going to come back on', we just don't know."
Heatwave conditions are likely to lessen by Sunday in Queensland and mid next week in the NT and WA.
Minor flood warnings remain in place for parts of Queensland, NSW and Victoria after all three states experienced wild storms over Christmas.
The storm death toll since Christmas in Queensland stands at seven while three people were killed in storms and flash flooding on Boxing Day in Victoria.
There's some relief over southern states with cooler conditions forecast over the next few days and no extreme heat alert.
