Member for New England Barnaby Joyce and NSW Farmers president James Jackson have backed the grants from the federal government.

Mr Jackson said the true cost of the fires, some of which were still burning, would become apparent during the coming weeks and months.

"This cost will be emotional, physical and social as well as economic," he said.

"It is evident in the north coast region, where bushfires caused significant damage to farms in November and December.

"The real cost impact is emerging in that area, with farmers now weeks into the recovery phase."

"While we await further details, it is pleasing that any off-farm income up to $100,000 annually will be exempt from eligibility assessment for the grants.

"We will work to ensure the delivery of these grants is not held up by red tape and paperwork."

Mr Joyce said it was important additional assistance for rural farming families.

"Large parts of the New England have been affected by bushfire in recent months and while many areas of our electorate are already eligible for some form of assistance, we are always looking at more ways we can help those in need," he said.

Mr Jackson said the government's commitment to employ an additional 60 rural financial councillors will also be appreciated, as farmers and their families rebuild their businesses.

"Support will continue to be valued by primary producers in affected areas. Farmers have lost stock, sheds, fencing, operating plant and many have seen precious hay and feed consumed by the flames," he said.

"Perishable foods, milk and oysters have not made it to market - dairy farmers have discarded milk, oysters have been tainted by a build-up of saline water, grapes have been tainted by smoke, and fruit trees have been burnt."
