A joint federal and Victorian government package will provide an extra $37 million to support people affected by bushfires in January.

About $33 million will go towards more than 100 temporary modular homes for those who lacked adequate insurance for damaged or destroyed properties.

An estimated 900 buildings, including 330 homes, were destroyed by more than 30 fires across 400,000 hectares in the state.

The fund also includes more than $4 million for legal services to help families, small businesses and producers responding to insurance and housing issues.

About $880,000 will go to the Rural Financial Counselling Service to increase the number of counsellors available. Services include free help for farmers negotiating with lenders and accessing government aid, plus mental health support for residents.

“Bushfires leave a lasting impact on farms, families and communities, which is why we’re backing Victorians with the support they need to recover, rebuild and prepare for the future.” state Agriculture Minister Michaela Settle said.

The funding brings the total recovery assistance to more than $420 million under cost-sharing provided through the Disaster Recovery Funding Arrangements.

Swiss catastrophe modeller Perils estimates the insured loss from the fires was more than $810 million.

“This additional support acknowledges disaster recovery is complex, and we must ensure all available measures have been undertaken,” federal Emergency Management Minister Kristy McBain said.
