It would only be the second time a catastrophic fire danger rating had been declared — the first was in November last year when fierce bushfires ravaged central Queensland.

In Far North Queensland, a home has been destroyed and several more threatened in a large and fast-moving blaze that broke out in Biboohra, north of Mareeba, during the hottest part of the day.

An aerial water bomber and 19 crews are battling that fire, which has been estimated to have burnt more than 300 acres of land in the area.

Queensland Fire and Emergency Services (QFES) spokesman Darryl Chaplain confirmed a home had been lost in the blaze.

"We did hear that the owner was returning back to his residence when he was informed of the loss," he said.

"Unfortunately there was nothing anybody could do to soften that blow."

A mango orchard was also destroyed and livestock threatened before the fire was contained about 5:00pm.

Police said there had been no controlled burns underway in the area, with Acting Inspector Rod Campbell saying police would investigate the blaze.

"We'll look at where the fire started and make some recommendations about whether anybody's responsible for it or whether it happened by natural causes," Acting Inspector Campbell said.

"The thing with a fire is, it destroys a lot of the evidence, so we'll do our best to investigate the circumstances and establish whether there was any fault."

One person was treated for smoke inhalation.

Crews will spend the night establishing containment lines in anticipation of similar conditions on Friday.

Hot, dry, windy conditions ahead

Bureau of Meteorology (BOM) senior forecaster Peter Otto said a cold front would move across the state today.

"Ahead of that there will be hot, dry, windy conditions," he said.

He said it was difficult to say what specific areas might experience catastrophic conditions.

"It's not helpful to try and pinpoint specific areas of catastrophic because it really is isolated in nature," he said.

"But generally speaking, around the Darling Downs and Granite Belt, that's the area where the largest risk is forecast as that area will be hotter and have the strongest winds."

QRFS acting regional manager Clinton Newman has urged people to prepare now and heed any warnings from emergency services.

"We're looking at fires that will be fast moving and difficult to control, so people who do not have well-prepared properties or who haven't got a plan, we're in the phase where it might be too late so their plan might be to leave early," Mr Newman said.

"We'll see fire bans from midnight Thursday night or Friday morning, through to midnight Friday night or Saturday morning … so pretty much all of Friday.

"So … make preparations today (Thursday)."

The areas facing a significant fire threat include Toowoomba, Southern Downs, Western Downs, Goondiwindi, Maranoa and the Balonne Shire council areas.

Blazes in Gold Coast hinterland not contained

Meanwhile, residents at Sarabah, south of Canungra, in the Gold Coast hinterland have been told to prepare to leave their homes, with conditions worsening.

People in the Gold Coast hinterland area are being impacted by heavy smoke that is reducing visibility and air quality.

QRFS regional fire manager for Brisbane, Wayne Waltisbuhl, told ABC Radio Brisbane crews are struggling to bring the Sarabah fire under control.

"That fire's not contained at the moment … it's in really rugged terrain, which makes it hard for firefighters to get access," he said.

There are no properties under direct threat, but fire authorities have urged residents to be ready to enact their bushfire survival plans.

"We have not seen it this dry for so long coming out of winter without any rain — it has really caused us some real concerns," Mr Waltisbuhl said.

"We are taking this forecast and the conditions we can see very seriously at the moment, this is one of the worst forecasts we can get.

'An event worth respecting'

Mr Otto described expected conditions on Friday as a "rare event".

"It looks like the highest fire dangers for September for at least six years, so it's certainly a rare event, and one worth respecting," he said.

He said "vigorous winds" were also expected to whip up a dust storm in western Queensland, affecting the south of the state into the weekend.

"We do expect some of that dust to reach the populated parts of the south-east coast," he said.

"So we expect through the weekend, a dust haze to emerge on the south-east coast, but it won't be as substantial as the dust over western Queensland."

He said wind gusts of 35-40 kph were forecast for southern districts on Friday, moving towards the east coast, ahead of a cooler change.

"Temperatures ahead of that cool change will be 7 to 8 degrees above average, maybe 9 degrees in some parts through tomorrow," he said.

"After the change, temperatures will drop to around the average, possibly below."

Other areas facing severe threat

The fire rating for the Central Highlands and Coalfields, Wide Bay and Burnett and south-east coast is expected to be severe on Friday.

There is currently one bushfire in the south-east at advice level, at Kurwongbah in the Moreton Bay shire.

Two other fires, at Upper Flagstone in the Lockyer Valley and Frazerview in the Scenic Rim, have been downgraded to notification level.

All three of those fires have been contained.

A very high fire danger remains in place for eastern districts.

There's a total fire ban for most of southern Queensland including Logan, Gold Coast, Ipswich, Somerset, Lockyer Valley and Scenic Rim.

Under a local fire ban, open fires are prohibited and all permits to light fire that have been issued in areas will been cancelled.
