David Moresi, 69, was a contractor working at the Gelantipy fire when he died as a result of a vehicle rollover on November 30 last year.

Mr Moresi was working with colleagues using bulldozers to create containment lines for the W Tree section of the fire.

He was flung from his vehicle during a rollover at the end of a shift.

He died at the scene.

Authorities confirmed today his death would be added to the official fires death toll, which now sits at five.

Emergency Management Commissioner Andrew Crisp said he had attended the funeral which was a "fitting tribute" to a wonderful life.

"Our thoughts and condolences go to David's widow, Judi, and family, given this tragic set of circumstances for someone who was working to keep our community safe," Mr Crisp said.

Forest Fire Management Victoria (FFMV) chief fire officer Chris Hardman described Mr Moresi as "a pillar of the community" and a "dedicated educator".

"He loved the bush, he inspired so many people to be in the great outdoors."

Mr Hardman said Mr Moresi was an "inspirational human being" who had supported the building of schools overseas, including in Thailand.

Mr Moresi is survived by his wife Judi and children Kelly, Luke and Nathan.

Mr Hardman said Mr Moresi taught his "many grandchildren" to shoot, hunt and fish and was building the "bushmen of the future".

"We do have a debt that the community can never repay," he said.

FFMV employees Mat Kavanagh, 43, and Bill Slade, 60, were killed while on the job this bushfire season.

Mr Hardman said it had been "a very difficult year" for the organisation.

"I think it's important just to reflect on the significance and the contribution and the sacrifice paid by these people to help protect our community," he said.

Buchan man Mick Roberts and Maramingo Creek man Fred Becker also died during the fires.

The bushfire crisis raging across the state has destroyed nearly 300 homes and continues to threaten lives and properties.

Smoke from the fires has blanketed much of the state, prompting health warnings as the air quality dropped.

Authorities have used milder conditions this week to make inroads on containing the huge blazes in East Gippsland and the north-east, but there are concerns storms could create hazards for crews on the firegrounds.
