DESPITE improved conditions over the past 24 hours, a widespread bushfire continues to cause headaches for residents at Ballandean and Eukey.

Almost 12 years to the week since the region's tragic 2002 bushfires, the blaze reportedly started after a slasher hit granite at a Ballandean winery on Monday.

Hot temperatures and strong south-westerly winds caused the fire to escalate quickly throughout Monday and Tuesday.

Ballandean and Eukey homes became most under threat between 2.30 and 4.30pm on Tuesday, as the fire was aided by winds of up to 45kmh.

At the time of print there had been no confirmed reports of damage to any homes at Ballandean and Eukey.

Operations officer Brett Roberts said the risk of the fire escalating had been reduced, but urged residents to stay wary.

"We are in a much better position than we were on Tuesday," he said yesterday afternoon.

"But people need to stay aware, and call triple zero if they feel immediately threatened."

Mr Roberts said the blaze was burning "within its containment lines", and had been mostly isolated within Girraween National Park.

Rural firefighters in partnership with Queensland Parks and Wildlife crews have been working around the clock defending properties, primarily through back burning exercises.

Mr Roberts said persistent water bombing would remain a key strategy.

"We'll be cranking it up again on Thursday morning," he said.
