A warning for an out-of-control bushfire north-west of Hopetoun has been downgraded to watch and act, as a number of fires burn in western Victoria.

The warning was for Burroin and Dattuck, with the fast-moving bushfire travelling from Euky Track in Wyperfeld Park.

A watch-and-act message issued for an out-of-control fire in the Brimboal area has since been downgraded to advice.

The Country Fire Authority (CFA) said there was no current threat to communities in the area but fire crews would remain at the scene.

A watch-and-act message for another fire burning at Poolaijelo, north-west of the Dergholm State Park, has also been downgraded to advice.

The CFA said people at Branxholme, south-west of Hamilton, were no longer under threat after fire in that area had been downgraded to advice.

But the CFA said the Branxholme-Byaduk Road has been closed between the intersections of Wallacedale-Hamilton Road and Ardoon Road.
