Queenslanders are being urged to stay cool and look out for one another as heatwave conditions start to be felt around the state.
The mercury is tipped to soar over the weekend before the heatwave peaks next week, and there will be no respite until Friday.
Temperatures will push towards the mid-30s in southeast Queensland as early as Saturday while inland areas are headed for the mid-40s.
Queensland Ambulance is urging vulnerable people, including the elderly and sick, to make a plan now to keep themselves cool.
Seniors Minister Coralee O'Rourke has also called on people to check in on anyone they think could be vulnerable in the heat.
"Popping next door with a cool drink for an elderly neighbour not only makes sure they're safe and well, it can also help beat social isolation and better connect seniors to their communities," she said.
Meanwhile Energy Minister Anthony Lynham assured Queenslanders there will be enough electricity to go round during the high demand, with 2000 megawatts of generation in reserve.
"That reserve capacity alone is more than enough to power one million homes during peak demand," Dr Lynham said.
He's urged people not to set their air-conditioners below 24C.
Brisbane is expected to get to 34C on Saturday, 35C on Sunday, and a peak of 36C on Monday.
Outback parts of the state will get an extra dose of extreme heat, with Birdsville expected to get to 43C on Friday, and 45C on Sunday.
