A Watch and Act message is still in place for Durham Lead, Grenville and Scotsburn, due to a very high fire danger rating forecast for today.
The Buninyong fire started at 2.30pm yesterday afternoon at Scott's Land and Nash's Road.
Firefighters have been able to stop the spread of the fire and blacking out has continued throughout the night.
Vic Emergency says staying close to a building you can shelter in is the safest option because conditions can change suddenly.
A relief centre has been set up at the Buninyong Leisure Centre.
