Crews are responding to reports of smoke in the area around Paddington Lane, off Moss Vale Road, a couple of kilometres west of the township.
It is believed there is a fire in inaccessible country, with crews saying it is burning towards Barrengarry Mountain.
Two crews have arrived at the scene and have sighted smoke.
A control post has been established at the location and with a crew going in on foot to investigate the source of the smoke.
