Strong winds are playing havoc with the fire at Sawyers Gully Road, Mullion.
The fire jumped Glenrock Road at about 6pm, but firefighters were able to stop the blaze just 50 metres from a house.

The fire had also threatened to leap Mountain Creek Road, but crews were able to stop it.

"The wind conditions are pretty blustery and erratic, so there's not much we can do with it right now," Southern Tablelands Zone Manager Peter Alley told the Tribune.
"Once the wind dies down we'll have a much better chance at getting at it."
Mr Alley said the wind is expected to die down significantly within the next three hours.

Mountain Creek Road is closed as a result of the fire spreading.
Mr Alley said more crews have been brought in and it's simply a "waiting game" at this stage.

With two bulldozers already on the scene, another has been sent from Yass to continue to work on establishing containment lines.
The mop-up job is expected to go overnight and into the morning.
