The blaze, which was started by dry lightning around 6:40pm (AEDT) on Friday in the Grampians National Park, had earlier been burning out-of-control sparking an emergency warning for the Dadswells Bridge, Heatherlie and Ledcourt areas.
Water bombers and other fire fighting aircraft helped to fight the blaze, which has now been contained.
The CFA's Richard Bourke says about 1,900 hectares of land was burned.
"The wind was very very strong last night and early this morning. the fire initially went in the direction of a south easterly direction and then when the wind swung around it pushed it towards a northeasterly direction which then pushed it towards Dadswell bridge," he said.
Much of the state is on alert with severe and extreme fire dangers declared in 13 districts. (more)
