The out-of-control and unpredictable bushfire is moving in a south westerly direction and could impact homes in the Sovereign Hill and Redfield Park areas as early as Wednesday evening.
60 firefighters are at the site and helitacs have been called in to assist in dousing flames which are up to two metres high. An evacuation centre has been set up at the Bendigo Bank building on Constable Street.
A bushfire watch and act has been issued for the coastal town of Seabird, north of Two Rocks, where an out of control blaze is burning.
Further north, a second watch and act alert has been issued for people in Eneabba.
Authorities said the fire, believed to have caused by a lightning strike, has moved across Brand Highway and is moving in a south westerly direction toward Leeman.

A watch and act alert remains in place for the town of Seabird, near Wanerie.
A DFES spokesman said aerial support had been temporarily suspended because of lightning.
Gingin publican Jamie O'Hanrahan said lightning was hitting the ground where the helicopters had landed.
Mr O'Hanrahan said Gingin had become a "ghost town" with only emergency vehicles driving through the streets.
He said the sky was black, smoke was in the air and lightning was hitting the ground every two seconds.
