FIRE crews are containing a bushfire eating through about 20 acres on the Sunshine Coast hinterland, with a total of 42 fires currently burning across the state.

The blaze on Hapgood Road, Landsborough, close to the Beerwah State Forest, is being held behind containment lines.

Queensland Fire and Rescue director of rural operations Peter Varley said the fire was one of three on the Sunshine Coast hinterland.

"The three latest outbreaks are at Conondale, Landsborough and Wamuran. The Wamuran one seems to be the bigger of the three," he said.

Mr Varley said all fires in the state were currently under control.

He said 122 vehicles and 15 aircraft working on fires across the state, with 108 recent deployments of staff and volunteers to help on more serious fires.

"At the moment everything's looking good," he said.

Mr Varley said a fire out at Chesterton Range near Charleville which was abandoned by fire crews yesterday in the face of deteriorating weather conditions was well on the way to being brought under control.

"They got back onto that one today and they're constructing containment lines around that one and they're quite confident they'll have that one contained," he said

He said the fire that threatened Crows Nest earlier in the week was under control, and crews were almost finished at the scene, while the fire at Greenbank on Brisbane's south was in a similar position.

"They were our biggest threats at the time," he said.

Mr Varley said fires at Mundubbera and Bunya National Parks were "looking good" and were being held behind containment lines, and the threat from a fire at Clagiraba and Mt Tambourine on the Gold Coast hinterland was also diminishing.

He said an expected change in weather conditions over the weekend would lead to welcome, if temporary relief for firefighters and fire-prone communities.

"The weather conditions for tomorrow are going to be easing, so they're going to be a lot better, and the forecast is for widespread showers," he said.

"That will help us a lot."

But Mr Varley said the respite against fires would be temporary, and the amount of dry vegetation in the state meant as soon as the weather dried up again the fires were likely to return.

"With the conditions I'm expecting again by the end of next week if we don't have any reasonable rain, depending on what starts I think we'll be pretty busy," he said.
