Victoria's Grampians bushfire contained

The large bushfire burning in Victoria's Grampians region has been contained.

Emergency crews will now turn their focus to returning fire-affected residents to their homes and opening roads so the areas are open to tourists ahead of the long weekend.

The 52,000-hectare fire, believed to have been sparked by lightning on Wednesday, has destroyed 27 homes.

Incident Controller Mark Gunning said crews spent the past few days working on back burning around the Mt Difficult Range near Halls Gap and strengthening containment lines.

Mr Gunning said the work was important to complete during the milder conditions before warmer weather and northerly winds this Thursday.

"As with any fire, the situation can change at any time," he said.

"While we don't expect any further spread of the fire, it is important that people stay up-to-date with local conditions."

Crews will continue patrolling the fire and removing dangerous trees, with the clean up to continue for days.

A separate fire burning in the area at Black Range, Bunjils Cave Road south-west of Stawell is not yet contained.

Advice messages remain in place for Roses Gap, Cherrypool, Dadswell's Bridge, Laharum, Ledcourt, Pomonal, Zumsteins, Wartook, Bellfield, Lake Fyans, Glenisla, Halls Gap and Brimpaen.
