Vic authorities work to stop fire looting

Locals wanting to return to their fire-ravaged communities in Melbourne's north are being given wrist tags in a bid to limit looting of damaged properties.

Residents from the Kilmore, Wallan and Craigieburn areas can obtain the tags that identify them as locals at relief centres at Romsey, Wallan and Seymour.

The plan is part of a management strategy for the area as some road blocks are lifted.

Fire Services Commissioner Craig Lapsley said residents are feeling frustrated but it is necessary to ensure some level of control.

"It's about ensuring that people do not go into these areas and take the opportunity of somebody's loss to then go through and be a thief in the area," Mr Lapsley said.

"That's a critical issue."

He said Victoria Police, fire authorities and local government were still assessing the safety of roads.

A falling tree limb even hit a firetruck on Monday evening, but no one was injured.

Mr Lapsley said there were concerns beyond weakened trees.

"In fire-affected areas you'll see that white posts on the side of roads are burnt," he said.

"Signage is burnt, bridges have got damage or part damage to them ... and even to the extent road surface itself could be damaged.

"It's about safety. not necessarily the safety of the fire burning, safety of the road user itself."
