A SHOWER of rain at 4.20pm extinguished a large bushfire at Leyburn which was burning on a wide front and had threatened a piggery.

A Queensland Fire and Rescue Service media spokeswoman said 12 Rural Fire Brigade crews and six urban units were on the scene at 4pm.

"We received the call at 1pm to the fire at Macquarie Dr," the spokeswoman said.

In windy conditions, the fire quickly caught on and was burning in an area 2km by 4km.

"Crews were using graders and backburning," she said.

"The fire was burning on a number of fronts with flames 4m high.

"It was not under control and burning on all sides."

While the firefighters had made progress, the rain at 4.20pm was a godsend as it extinguished the fire.

It was believed to be the only shower in the fire region but proved perfect for the firefighters battling the blaze.

The only rain predicted by the Bureau of Meteorology yesterday was on the coast from the Gold Coast to Fraser Island.

The firefighters stayed on scene to ensure the area was safe.

By 6pm, half of the units had left the scene.

No property or buildings were damaged in the fire which did threaten a piggery.

There was no information available at the time of going to press last night about how much grass and bushland had been burnt in the fire.

It is rare for a fire to burn on such a wide front in the grazing area west of Warwick.

Leyburn police were also on the scene.

There were no injuries to firefighters.
