Brisbane has sweltered through its equal-hottest December day on record.
The temperature hit 41.2C in the CBD on Monday, which equalled the record set in 1981.
That figure was reached at a different location to the current bureau monitor, which was moved in 1994.
Several areas west of Queensland's capital also recorded 40C temperatures.
Gatton reached 43.2C while the Ipswich suburb of Amberley reached 42.2C.
At Beaudesert temperatures topped 41.1C, while Archerfield, just west of Brisbane, got to 40C.
The Bureau of Meteorology said the southeast corner will see a slightly cooler change for the rest of the week, with Brisbane's maximum on Tuesday to drop to 30C.
But other parts of the state can expect a scorcher.
Birdsville hit 44C on Monday and the mercury is expected to rise to 47C on Wednesday before levelling off and sitting at about 45C for the rest of the week.
"We have very hot temperatures across the interior and the southwest, continuing right through this week," meteorologist Lauren Pattie told media on Monday.
Little rain is forecast across the state for the rest of the week.
