Firefighters are battling more than 80 blazes across Queensland as they prepare to make significant gains amid easing conditions on Thursday.
It comes after a helicopter pilot crashed while waterbombing a fast-moving grass fire at Pechey on Wednesday, and fresh firefighting crews arrived from New Zealand, Tasmania and the Northern Territory.
The pilot has been treated for non-life threatening injuries after efforts to bring the fire under control went awry. An emergency warning for that blaze remains in place.
Much of southern Queensland is covered by a severe fire danger warning but a brief reprieve is expected when conditions ease on Thursday.
Moist coastal winds will blow through Thursday ahead of westerly winds on Friday.
But forecasters say the westerlies will push extremely dry air back towards to coastal fringe.
"There is an extended forecast that we are not out the woods by any means," Acting Queensland Fire and Emergency Services Commission Michael Wassing said.
An emergency warning remains for a small island community on the Sunshine Coast that is only accessible by sea or the cross-river ferry.
It is the second time in a number of days residents were told to get out.
Dave Wright readied his own boats to flee if the situation got worse.
"The dinghies are in the water and primed to go," the Noosa North Shore rural fire brigade member has told The Sunshine Coast Daily.
"It's how we travel every day."
A large fire is still burning in difficult terrain near the five-star Spicers Peak Lodge on the Southern Downs, but it is not directly impacting properties.
Resort managers knew the fire was coming days ago, telling guests to scrap their plans to stay.
Only a couple of staff were still on-site with authorities on Wednesday.
"It would have to be an incredibly devastating fire, I believe, to get to the lodge, and I think the people there will have opportunities to be safe even if it is a really bad situation," owner Graham Turner told ABC radio.
"We're worried, but I'm sure there's a lot of people in far worse situations."
Authorities say the sheer size and number of fires burning in bone dry swathes of land that are also difficult to access is their biggest concern.
There are more than a dozen fires between Brisbane and the New South Wales border, including in the Scenic Rim, that officials are anxiously watching.
It is there that 11 homes and the historic Binna Burra Lodge in the hinterland were destroyed by fires that ravaged the area in September.
"With the volatility of the wind, the extreme temperatures and the pre-heating already of the fuels, events can unfold very rapidly and we're stressing the urgency of being prepared," mayor Greg Christensen said.
A blaze in Cobraball near Yeppoon in central Queensland continues to be of significant concern.
It has claimed 13 of the 14 houses lost in Queensland since late last week.
Conditions are expected to ease on Thursday, but temperatures are heating up further into the weekend.
Premier Annastacia Palaszczuk has asked Queenslanders to put their community above themselves and avoid reckless acts that could spark a fire.
Health officials have warned vulnerable people to stay indoors, with air quality expected to plunge again on Wednesday as smoke from the Queensland and NSW fires spreads.
