High fire danger for Qld's Wide Bay

Residents of Queensland's Wide Bay-Burnett region have been warned to be on alert into the weekend amid heightened fire danger.

The Queensland Fire and Emergency Service (QFES) says a very high fire danger rating will be in place on Saturday before an expected reprieve on Sunday.

QFES North Coast Regional Manager Peter Hollier says blazes could become difficult to control, potentially placing homes at risk.

"A spark from power tools, mowers or farm machinery could be enough to start a small fire," Mr Hollier said.

"Combined with dry conditions and a very high fire danger rating, a small fire has the potential to spread quickly."

The Bureau of Meteorology expects the region to experience up to 30C.

Crews have already been battling a vegetation fire at Cabbage Tree Mountain, west of Maryborough, that began last week and has been causing a large smoke haze in the area.
