SCENIC Rim mayor Greg Christensen has confirmed that most of the people displaced by the Sarabah fire have returned to their homes.
"Some have gone back to challenging days ahead," he said.
"And some have not been able to go home because full replacement or structural repairs are needed."
Assistant QFES Commissioner Kevin Walsh said improved weather conditions would allow a lot of the local fire crews to stand down and get a day or two of well-earned rest.
"They've worked tirelessly," he said.
Mr Walsh said with the arrival of a third task force of 50 interstate firefighters, local firies would be replaced at the fire front.
He said the coming days would allow firefighters to install robust containment lines in readiness for when the wind picks up again towards the weekend.
QPS Chief Superintendent Ben Marcus said police investigators were working on the ground to determine the cause of the fires but would not comment on whether there were suspicious circumstances involved.
"They do know the area where the fire was first reported," he said, adding that whether or not anyone would face charges would be up to the investigation findings.
Superintendent Marcus said Binna Burra Road was closed after an assessment by TMR could not guarantee that the road was safe.
"Lamington National Park Road is open but also being assessed by TMR," he said.
