Fire crews have spent the night battling an intensified bushfire on North Stradbroke Island, near Brisbane.
The fire flared late yesterday afternoon, fanned by strong winds.
Several residents were forced to temporarily leave their homes.
The bushfire started around 10 days ago and is burning within containment lines.
Incident controller David Sutch says water-bombing helicopters will be deployed again today.
"Things have quietened down a little over the night," he said.
"There is still some active fires and we still have some crews in place that have been working throughout the night.
"We are hopeful that we will get the upper hand early this morning."
But winds could present a problem again today.
The weather bureau has forecast fresh to strong and gusty south-easterly winds over southern Queensland waters.
Townsville blaze still alight near property
In the state's north, fire crews this morning will return to a blaze that has flared up again on the outskirts of Townsville.
It started at Lynam on Friday afternoon and is still burning near property.
A Queensland Fire and Rescue spokeswoman says a bulldozer has helped create fire breaks near Mill and Page Roads.
Crews have contained a large grassfire that caused a smoke hazard yesterday at Yabulu, north of Townsville.
High alert extended
The Rural Fire Service says it will remain on high alert for longer than usual this season.
Spokesman Ken Beasley says hot, dry and windy conditions are continuing across Queensland.
"The bushfire season traditionally finishes with the onset of the wet season.
"However because of the late onset or the pending onset of the wet season, the operational period has been extended through to the end of January because we're still experiencing fire conditions."
