UPDATE 9:20am ONLY one fire continues to burn out of control in Victoria while the two largest ones have been contained.

The 25,000-hectare Wilsons Promontory fire is the last one burning outside containment lines after firefighters managed to bring two key blazes under control yesterday.

Cool, wet weather helped firefighters get on top of the two largest bushfires - the giant Kilmore East Murrindindi North Complex fire and the Bunyip Ridge blaze - by late yesterday.

The Bunyip Ridge fire blackened 25,200ha while the Murrindindi fire razed more than 168,000ha.

Department of Environment and Natural Resources spokesman Kevin Monk said that while Wilsons Promontory had also received rain, the fire was still not under control.

"There's still some quiet activity in places even after the rainfall, that's why we haven't been able to declare that fire contained,'' he said.

In another good sign, interstate fire crews also continue to be allowed to return home.

Some remaining firefighters would be directed to other important work at the bushfire scenes, Mr Monk said.

"We have been able to start work on recovery and rehabilitation of the burnt areas - working on tracks, drainage rehabilitation to minimise erosion,'' he said.

Meanwhile, the first bodies of victims from the bushfires can be released to their families from today, almost a month after the deadly fires swept through the state.

State coroner Jennifer Coate said the bodies of four victims were likely to be released today but it depended on the circumstances of their relatives, who would have to start funeral arrangements.

The official death toll stands at 210 but that could rise as police continue their search for more bodies in the remains of homes in Marysville and Kinglake.
