Outback Australia is enduring sweltering conditions, with temperature climbing to record high in some regions of South Australia and Queensland, local media reported on Friday.

After going through the worse floods in 200 years across states of Queensland and Victoria, outback Australia is now enduring another extreme weather condition.

South Australia has sweltered through six days of high temperatures, recording its hottest day in 21 years, while Queensland's far west is also heating up.

On Tuesday, the South Australian outback town of Roxby Downs reached a record 48.5 degrees Celsius.

According to the weather bureau's Matt Collopy, other parts of the state have felt the severe heat too.

"Woomera was 48 degrees - that's the hottest temperature since 1960," he told ABC News on Friday.

"Port Augusta was 47 degrees and again that was their hottest temperature for January since 1968."

Adelaide is also heating up and is forecast to reach 39 degrees on Saturday, 42 degrees on Sunday and 41 degrees on Monday.

Meanwhile, in Queensland's far west, Birdsville and Bedourie reached 47 degrees on Thursday.

The weather bureau said Bedourie has recorded its hottest day in history for the 47 degrees on Thursday.

Urandangie reached 44 degrees and Charleville 41 degrees and the weather bureau expected more hot conditions across the towns in far west Queensland on Friday.

According to Darren Collins from the Birdsville Hotel, locals are taking it in their stride and the beer is flowing.

"Our temperature gauge out the front of the hotel here reached 50 degrees and ours always does vary a couple of degrees from the official readings," he told ABC News on Friday.

"It was extremely hot and with the wind, it made it even worse.

"When you are out in around 50 degrees - with that wind - it's just like being in an oven - there wasn't a lot of movement around that's for sure," he said.
