She is living on a 60-metre platform in a tree in the Tyenna Valley, about 50 kilometres from a fire burning in the Lake Repulse area.

Ms Gibson says she is prepared to abandon the protest if the situation becomes dangerous.

"I'm lucky enough to have quite a good view of the surrounding area," she said. "I'm up quite high, so just keeping an eye on if I can see any smoke or any fires in the distance as well."

Anyone seeking refuge from the fire is being urged to go to the Ouse Community Hall.
