Residents took shelter at the Nerriga pub as the fire passed as two Windellama fire crews assisted Lake George zone throughout the night. They worked mainly around the town and along Nerriga Road.

Property owner in the Nerriga district Jim Sturgiss told the Goulburn Post the family home at Sassafras was lost in the blaze.

"I also know that there were six homes lost up there at Sassafras," Mr Sturgiss said.

"That was about half the houses that were up there, so there could be more houses that are lost other than that."

He said there were also losses of homes along the road that turns off before Nerriga, just before the museum (Willow Forest Rd).

"There are a lot of houses up there in 100-acre blocks. There are 8-10 houses in a group area there and a bloke who got out told me that most of those houses there went, but there are some left.

"There will be a large number of houses gone at Nerriga"
