A WATCH and act alert is still current for an out-of-control fire near Violet Town in north eastern Victoria.

But cool weather conditions had slowed the blaze.

The fire is south of the Hume Freeway near Boho and has already burnt about 1200ha of mostly private land since it started on Sunday.

A 60-year-old man suffered burns on his legs as he fought the original grassfire near on Sunday and authorities have warned it could burn for days possibly weeks.

Shepparton incident control centre spokesman Alex Caughey said part of the fire was in rough terrain making it hard to access, but they were focussed on building containment lines.

"The good news is the fire activity has reduced with the milder weather conditions," Mr Caughey said.

He said no communities had been threatened and no assets lost and 250 firefighters were attending the blaze along with 60 vehicles and six aircraft.

Firefighters were also working on two controlled fires at Harrietville near Mount Feathertop in the northeast, and huge blaze in Gippsland, to the southeast, which destroyed homes, livestock and burnt through more than 70,000ha.

The Gippsland Aberfeldy-Donnellys fire was still not controlled and 150 firefighters remained in the area with five bull dozers and three excavators building containment lines.  

The Department of Primary Industries reported 180 farms were affected by the fire mainly in Aberfeldy, Seaton, Dawson, Glenmaggie and Licola.

Approximately 186 head of cattle, 21 sheep and four horses and donkeys were killed in the blaze and about 480km of fencing was burnt out with two farmers losing more than 50km each.

The fire continued to burn in remote country and incident controller Dennis Matthews said it was spreading slowly with the mild weather but not yet fully contained in the 220km of control lines authorities had built.

Mr Matthews said the fire was in rugged country and crews were concentrating on tidying up the edges and attacking hot spots in the Black Ranges.

"The hot spots are on a flank which is not bounded by containment line in the Black Ranges east of Mount Useful in tough and hard country," Mr Matthews said.

"We are in a holding operation the fire is not finished.

"What is of concern is if the fire continues to run and gets into the Avon Wilderness this is tough country . . and it's very tough to manage and it could advance east."

Prime Minister Julia Gillard and Victorian Premier Ted Baillieu visited the areas affected by the Gippsland fire yesterday.

Ms Gillard said she wanted to visit the area to let communities know they were thinking of them, but urged Victorians to be prepared and vigilant.

"We are yet to face what could be the worst of the bushfire season. Often in Victoria the weather in February is at its hottest and most dangerous," she said.

The third fire near Harrietville had burnt about 3200ha and was still burning in remote dense bushland.

The fire threatened the township of Harrietville and forced the evacuation of tourists and closed the Great Alpine Rd and Dargo High Plains Rd on Friday.

"It's still going and burning within containment lines," state control centre spokeswoman said.
