Three crews were brought in last night to fight a fire at Yambla Range, east of Gerogery, that has burnt 150 hectares of bush. They will be relieved by three or more crews today.

The fire broke containment lines on Thursday night, but was considered contained last night.

NSW Rural Fire Service duty officer Julie Bartlett said a considerable amount of backburning had been done.

“There was a bit of an outbreak this morning but we fixed that up,” she said.

Ms Bartlett said graders were used to put in more control lines yesterday, with firefighters supported by a water-bombing helicopter.

Eleven tankers and 35 firefighters worked to establish the new containment lines that were put in place by heavy machinery on Thursday night.

Graders were also used in yesterday’s efforts to put out a fire in the Upper Wantagong area, near Lankeys Creek, that has burnt out about 35 hectares after a lightning strike.

“That one is burning in really rough terrain,” Ms Bartlett said.

Firefighters also carried out a large amount of backburning.

Ms Bartlett said the main task with that fire was to prevent it spotting into a private pine plantatation off the Jingelic Road.

She said the Rural Fires Service was confident it could stop the blaze spreading.

Four tankers and 12 RFS firefighters tackled the fire yesterday, again assisted by a water-bombing helicopter.

Hume Forests provided two bulldozers and additional crews to fight the fire.
