A lightning strike on January 15 caused the fire, which burnt about 55,100 hectares and impacted communities including Brimpaen, Laharum, Wartook, Roses Gap, St Helens Plains and Dadswells Bridge.

It destroyed more than 30 homes and one life was also lost.

Wimmera fire-fighters are maintaining a presence on the fire-ground.

Department of Environment and Primary Industries Wimmera district land and fire manager Russell Manning said up to six slip-on units were continuing to patrol the area and respond to any reports of smoke.

"But we're not expecting any further breakaways from that fire," he said.

"We're expecting it to remain within the control lines, after being tested on many fronts with extreme weather in the past few weeks."

Mr Manning said crews secured the complete perimeter of the fire at the weekend.

He said said fire crews had been working on various areas of the fire and would continue to patrol control lines around the perimeter over the next few weeks.

"These fire-fighters have worked in very difficult terrain and under arduous conditions, including days of extreme temperatures to control this fire," he said.

Mr Manning said smoke from the fire might still be visible in the next few days as winds shifted in direction and strength.
