Queensland Premier Annastacia Palaszczuk has issued an urgent plea for residents near Deepwater in central Queensland to leave their homes immediately due to the ongoing threat from a bushfire fanned by an unprecedented heatwave.
"This is not an ordinary fire… this is a dangerous fire that could result in a firestorm," Ms Palaszczuk said late on Tuesday afternoon.
Her comments came after the Bureau of Meteorology (BOM) issued an extreme fire danger warning for the Capricornia for Wednesday.
At 5:40pm on Tuesday, the Queensland Fire and Emergency Service (QFES) issued an emergency warning for Deepwater, Baffle Creek, Rules Beach and Oyster Creek, saying leaving immediately was the safest option.
A separate warning to leave immediately was issued for Dalrymple Heights at 7.20pm (local time).
"I know this is extremely distressing for families and we are there to help you, but you need to listen to the authorities and you must leave immediately," Ms Palaszczuk said.
"It's the kind we have not seen in Queensland before and the time to leave is now.
"We are seeing unprecedented heatwave conditions in Queensland. We have records that have been smashed, records that we haven't seen in 50 to 60 years, so these heatwave conditions are going to continue for many days to come."
Gladstone Mayor Matt Burnett said there could still be hundreds of people who had not evacuated from Deepwater, Baffle Creek, Oyster Creek and Rules Beach.
"We don't know how many people have stayed there, we've had police doorknocking and SES doorknocking for the last three days and some people have decided to stay," he said.
Earlier on Tuesday, QFES incident controller Craig Magick said they were concerned the Deepwater fire could cut the bridge at Baffle Creek, the only way in and out of the area.
"If the bridge gets cut, people will be stuck within that area during the fire," he said.
QFES Commissioner Katarina Carroll said there are 80 fires burning across the state, but she expected that number to increase dramatically over coming days.
A separate bushfire at Finch Hatton, west of Mackay in north Queensland, also prompted QFES to urge residents to leave but was later downgraded and residents who had left were safe to return home.
Police had declared an emergency in Finch Hatton and urged people in the area to register at the local showgrounds.
"The next two days in particular, the combination of the climate, the heat, the fire is just absolutely horrendous," Commissioner Carroll said.
"There is no rain in this and there is no respite - these are conditions that we've never seen before."
Debbie Gussey, who manages a resort at Eungella, on the mountain range overlooking the fires, said conditions had worsened throughout the day.
"You can actually see from the cabins how the fires have increased in intensity and you can see a few other spot fires have started as well," she said.
Ms Gussey said the road in and out of the area was closed, meaning the school bus could not get through to take children home from Mirani.
"Alternative arrangements had to be made to get them from Finch Hatton either back into town to relatives or family friends' houses," she said.
Meanwhile, BOM state manager Bruce Gunn said temperature records had continued to tumble.
"We've seen all-time temperature records absolutely shattered, records that have stood for 60 or 70 years," Mr Gunn said.
"We see extreme fire dangers in Queensland maybe once every two years - we've seen it three times or more in four days.
"While the peak of the fire danger is tomorrow, the conditions are ripe to keep fires going for several days yet."
Among the maximum temperatures recorded on Tuesday, Cooktown reached 43.9 degrees Celsius, Innisfail hit 42.3C, and Townsville Airport recorded a November record of 41.7C.
