Worried Qld firies act before flare-up

Firefighters battling to contain a massive blaze in Central Queensland before conditions flare up again are hoping their preparations will hold.

Fire authorities near Yeppoon are worried about rising temperatures and strengthening winds forecast for Wednesday.

"We hope to undertake enough action today ... so that tomorrow we have a better success of keeping the fire within the existing lines," Rural Fire Service's Inspector Wayne Kapernick said.

The efforts of exhausted firefighters, who have been fighting a blaze burning near Cobraball, Bungundurra, Maryvale and Lake Mary for days, have been boosted with firies from elsewhere in the state.

"It has been a long campaign (that is) taking a tremendous toll," Inspector Kapernick said.

At least 11 homes were destroyed in the blaze that by Monday was 30-kilometres long.

About 65 per cent of the Cobraball fire was contained on Monday but firefighters were making slow progress on Tuesday, he said.

"Given the dry conditions we've got a lot of work to do to make sure those edges are safe and hold up to tomorrow's conditions with the increased wind strength so there's no escape of embers," he said.

Queensland Fire and Emergency Services acting commissioner Mike Wassing said he was comfortable with the status of the state's largest blazes but containment lines would be tested when the winds shift.

Backburning operations at Cobraball have been stalled until winds drop, making it safe to continue.

Bureau of Meteorology forecaster Dean Narramore said winds would pick up late on Tuesday and Wednesday morning with gusts up to 60km/h from late morning or early afternoon.

Tuesday's fire danger rating for the Darling Downs and Granite Belt and Southeast Coast is already severe and will remain so on Wednesday and also take in Wide Bay and Burnett.

There is likely to be little reprieve on Thursday before temperatures and winds increase again from Friday throughout the weekend.
