A band of lightning which moved through the area sparked the fires which appear to be centred around Narrabri-BingaraRd.

Rural Fire Service crews were quick to swing into action, calling in their NSW Fire and Rescue colleagues to assist.

Four crop dusters are spraying the area and four Rural Fire Service (RFS) brigades are involved including the Narrabri and  Baan Baa crews.

Seven aircraft have been called from Gunnedah, Moree and Coonabarabran to assist in the efforts.

A specialist air attack supervisor has also been called to the scene to supervise the firefighting efforts from the air.

It is believed some houses are in the line of fire, particularly those along Gun Club Road. It is believed one shed has been damaged.

One fire has reportedly burnt out 100 hectares this afternoon.

In a message to the public this afternoon, RFS spokesman Brendan Doyle asked residents to be the “eyes and ears” of firefighters and report any fires which may be unattended.

“We’re waiting for the rain band to move through the area, it was behind the stormfront,” he said. “We’re not sure how much rain it’s going to bring but we want to get on top of it as quickly as possible.” 

Mr Doyle said the fire was burning near properties but current weather conditions did not appear to be threatening. He said residents near the fires were urged to take advice from fire crews on the ground.

Meanwhile, Rural Fire Service volunteers have a 20 hectare bush fire east of Bonay Linton Rd, Thirldene, under control.

Also a 14ha bush fire at the intersection of Oxley Highway and Marys Mount Rd, Gunnedah , also is under control.
