More than 120 firefighters are continuing to battle a fire sparked by a lightning storm in Victoria's west.
Lightning started five fires across the Casterton area in Victoria's west yesterday afternoon.
Three of the fires were brought quickly under control and firefighters were able control another fire at Martin's track overnight.
But one remaining fire about 18km west of Casterton has burned more than 2000 hectares and may not be considered under control until late today, a Department of Sustainability and Environment (DSE) spokesman said.
"The fires continue to expand. It's burning in stringy bark vegetation and it's generally a wind-driven fire," he said.
"We've got plenty more work to do to bring it under control."
Bulldozers are continuing to build control lines while fire bombers are helping from above.
While no properties are at risk, the fire will likely burn into private plantations, the spokesman said.
He warned motorists to stay away from bushfire areas.
"The fires have not been in close proximity to houses. (They are in) state forests principally and small areas of plantation."
Bushfires in Little Desert National Park have also burnt more than 400 hectares of land, but all fires were contained today with aircraft continuing to monitor the blazes.
No properties are at risk.
