It comes after the Grampians Northern Complex fire was contained overnight Monday.

The Department of Primary Industries and Environment also issued a watch and act message for Stawell and the Black Range on Tuesday night as a bushfire continued to burn about seven kilometres south of Stawell.

Incident controller Andrew Morrow said crews working at the Grampians fire had focused on establishing and strengthening containment lines and back burning around the Mt Difficult Range near Halls Gap in the past few days.

"Communities and visitors to the Grampians should be mindful that emergency services will be working in the area for some time yet and over the next couple of days, there may be smoke visible from aerial ignitions to complete back burning in the Rose Creek Road section,'' he said.

Separate to the Grampians Northern Complex, a fire continues to burn at Black Range, Bunjils Cave Road south-west of Stawell.

Mr Morrow said unexpected conditions caused the fire to cross containment lines on Sunday and overnight.

He said it had moved towards the Bullochy Mary Road and Ganawarra Road area.

“The focus has been on a direct attack of the northern part of the fire and consolidating containment lines to provide protection to the township of Stawell,'' he said.

"Overnight crews have completed a control line from Bunjils Cave Road to Burrong Basin Road and have also built a containment line around the speedway complex.''

Mr Morrow said work would continue around control and containment lines and in putting in place an earth break from Brown Lane, up north to Monaghan Road.

He said a number of key roads are closed including Bullochy Mary Road and Bunjils Cave Road between Pomonal Road/Ganawarra Road and Glue Pot Road.
