EARLIER: The Bruce Hwy has been reopened at Childers, south of Butchers Rd.

EARLIER: The Bruce Hwy has been closed at Childers, south of Butchers Rd, due to a bushfire.
About seven Queensland Fire and Rescue Service (QFRS) and Rural Fire Service Queensland (RFSQ) crews are on scene at the large bushfire near the Bruce Highway at Doolbi, south of Childers.
Queensland Fire and Rescue regional manager Peter Hollier said the fire was spread about 15 acres and estimates that it could potentially grow to about 35 acres.
The fire broke out at about 10am and crews are currently working to contain it.
The fire is not threating any property but is causing a lot of smoke, closing the Bruce Highway in the area.
Firefighters are likely to back burn later in the afternoon and smoke is expected to linger in the area for the rest of the day.
Residents with respiratory illnesses are advised to close their windows and doors and keep medication close by.
Motorists are advised to avoid the area and drive with caution.
