A total fire ban is in place across Victoria with firefighters and emergency services working through the night to contain four bushfires.
An evacuation order has been issued for Labertouche North.
The blaze is expected to affect the area on Sunday, with authorities advising residents to prepare to evacuate.
Hot temperatures are expected again across the state on Sunday, with the ban in place until midnight.
The fire danger rating is severe for the central district and very high for the rest of the state.
“This means that if we have fires in the landscape, they could challenge firefighters,” the Bureau of Meteorology senior forecaster Tom Delamotte said.
“This is the hottest start to autumn in 30 years, following the hottest summer on record,” he said.
Dozens of communities are still at risk with at least four fires burning out of control, and residents in nearby towns told to take shelter or leave before it was too late.
A massive 3400-hectare blaze is tearing through the Bunyip State Park, near Tonumbik, about 65km east of Melbourne, after four smaller fires merged on Saturday.
The bushfire prompted an emergency warning and has been edging towards the Princes Freeway, which remains closed at Nar Nar Goon.
Three other fires are also expected to burn into the night with a fire at Budgeree in the LaTrobe Valley prompting an emergency warning.
The fire is burning just 1.8km away from Yinnar South.
“Leaving now is the safest option, before conditions become too dangerous,” the warning states.
At Licola in the state’s east, two fires joined and destroyed 1000ha, with embers and burnt material blowing around the town.
Farther east, a bushfire at Dargo was downgraded on Saturday, but a Watch and Act warning remains.
Around 30 fires are still burning across Victoria, with up to 20 of the blazes caused by dry lightning.
