As the hot weather and winds that fanned severe bushfires in southern Queensland ease, residents and businesses owners are seeing the full extent from the fires that have raged statewide since last week.

Key points: About 70 fires are still burning in Queensland

About 70 fires are still burning in Queensland Crews have taken control of the large Peregian blaze and residents are returning home

Crews have taken control of the large Peregian blaze and residents are returning home Weather conditions have eased, but are expected to intensify again on Friday

The emergency declaration for Peregian Springs and Peregian Beach on the Sunshine Coast has been revoked and all residents were allowed to return home on Wednesday, including those from Weyba, Weyba Downs and Peregian Breeze.

Queensland Fire and Emergency Service (QFES) Inspector Chris White said crews were able to gain the upper hand on the large Peregian bushfire.

"We have some predicted wind speeds that may be a problem [on Friday and Saturday], but technically with the support we're hitting this fire with at the moment everything should be blackened out in that Peregian area," he said.

Peregian beach resident Sunny Marx found his house spared from the fires.

"We're just worrying more about the neighbours and seeing how we can help," he said.

"It was pretty scary, it was raining down embers. I jumped up on the roof to have a look and see how bad it was.

"It was this huge wall of red and smoke coming towards us and this really loud roaring noise.

"Thank you to all the firefighting crews that came and helped us, they did a terrific job."

Businesses remain closed but owners were all in good spirits with minimal damage.

Teens charged over alleged deliberately lit fire

Police Commissioner Katarina Carroll said on Wednesday the cause of 10 fires being investigated by the newly-established Taskforce Overcross had been solved, with 11 people, some juveniles, dealt with by detectives.

"In some cases it's just kids lighting fire for fun [and] that fire has gotten away and impacted very badly," she said.

"[While] other kids got together and purposely lit fires, and in other cases there have been recidivous offenders around arson and police have dealt with them appropriately."

Police said in a statement later on Wednesday afternoon that two teenagers had been charged over an alleged deliberately lit fire that destroyed bushland and forced residents to evacuate their homes in the Peregian area on Monday.

A 14-year-old boy from Peregian Springs and a 15-year-old girl from Coolum Beach girl were charged with endangering particular property by fire.

Meanwhile, Southern Region Assistant Commissioner Mike Condon said there was evidence to suggest the fire near Stanthorpe on the Granite Belt, that destroyed at least five homes over the weekend, may have been accidentally lit.

Firefighters praised for their efforts

Emergency crews have been commended for their efforts across the state.

One Ballandean rural firefighter, Aaron Cox, was praised on social media by his wife Bindi, who took an emotional photo of the man right after fighting to save his own home from the fires.

"This is a man who has fought hard for his community since Friday and has just finished the epic fight to save his own house when he had nothing left in the tank to begin with," Ms Cox wrote on Facebook.

"I know you think this photo makes you look vulnerable but in that moment we both felt this.

"No-one understands what a bushfire does to you until you have to fight."

QFES Acting Deputy Commissioner John Bolger said exhausted firefighters still at work would be relieved by crews from Victoria and South Australia.

"It's been a wonderful national effort," he said.

"I'll be honest, the only way we can fully extinguish all those fires is when we get some rain, we can build containment lines, we can hold them in place but in the difficult terrain to extinguish them [would be hard].

"We are relying on rain and unfortunately there's none on the radar."

Currently, there are about 70 fires burning across the state.

Since the crisis began last week, 17 houses have been destroyed, including one in Peregian Springs, 11 in the Scenic Rim, four at Applethorpe and Stanthorpe and one at Biboohra in Far North Queensland.

Five businesses were gutted at the weekend in Binna Burra, in the Gold Coast hinterland.

Gold Coast hinterland residents start returning

Better conditions in the Gold Coast hinterland and Scenic Rim have meant residents have started returning home.

Lisa Groom lives on a street near Binna Burra Lodge that was completely devastated by the fire.

"In my street we've lost 11 houses, I think, and some of those people are not going to be able to come back for a while, or maybe never," she said through tears.

"The childhood house I grew up in is literally right to the left of the whole lodge and we haven't been able to get up to see that yet.

"This is a rainforest. This is supposed to be a wet environment — a moist and nurturing environment — and it's dying, it's dying."

Three schools in the area remain closed, including Beechmont and Numinbah Valley state schools and the Numinbah Valley Environmental Education Centre.

QFES chief superintendent Kevin Walsh said there was potential for fires to flare again later this week, so people needed to remain alert.

Higher temperatures and stronger winds are forecast from Friday in the state's south-east, increasing the fire danger.

Nursery owner David Higgins was evacuated on Monday afternoon and has been staying at the community centre since.

He said although the fire did not reach his property, his plants had suffered.

"Heat and wind are the worst things for us. We haven't had rain since March — that's the biggest thing," he said.

"If you look around the forest that we're surrounded by, mature trees are dying and falling over and creating more of a fire hazard."

'I am not happy at all'

Fire crews were aerial water bombing near a Far North Queensland Indigenous community today, where a blaze is burning in inaccessible land.

The fire near Lockhart River on Cape York started several days ago in woodland but has spread to nearby Iron Range rainforest.

Lockhart River Mayor Wayne Butcher said he was not happy with the response to the blaze and said more should have been done earlier.

"I am not happy at all," he said.

"Straight after [Cyclone Trevor] we knew a lot of rainforest would be damaged and it was always going to be a race to try and put measures in to prevent the rainforest from burning — now it's burning."

Queensland Parks and Wildlife said it was not clear how much of a rainforest had been destroyed by the bushfire.

Ranger Marty McLaughlin said extensive damage from a cyclone earlier this year had made managing the blaze more difficult.

"The issue is just the amount of debris on ground and because of the access difficulty on ground between cyclone debris," he said.

"It means that the aerial attack is potentially the only way you can deal with fire in some of those locations."
