Mr Wolf said it was time to amp up fundraising as teams of volunteers head back into the Upper Murray to help farmers rebuild fencing infrastructure this weekend.

The Wodonga resident and army veteran said families in fire-affected regions were struggling to restore livelihoods but their plight had been "wiped away" by the coronavirus crisis.

"Australia has experienced its biggest natural disaster in history and now you barely hear about it," Mr Wolf said.

"Farmers have had to put more focus into their crops and it's slowed the rebuild.

"Some are still picking up the ashes of their homes.

"Many are struggling financially and they need assistance from a labour point of view to get fences back up.

"Also it's taking a lot of detail and effort to fill in the mountain of paperwork required to get assistance."

Mr Wolf, who was motivated to help after his family's farm was burned out in the December 2015 fires at Barnawartha, has put a shout-out for dollar support to see his mission accomplished.

He is rallying the troops - a "family" of 7000 Facebook followers - for the next stage of the recovery campaign.

"Covid (sic) is easing but the fire recovery hasn't stopped!" he wrote on his Fencing For Fires page.

"It's not always about dollars but creating some noise to ensure the people with the dollars that have been allocated for fire recovery hear.

"FFF has never left the fire grounds since day one.

"We've done more with $30,000 raised ... than I could ever have hoped for.

"However what could we do if the heads of the agencies actually put some dollars to where it makes a difference on the frontline?"

Mr Wolf said the grassroots basis of FFF was the best thing about it.

"People have cooked me dinner, offered me a bed for the night and friendship for life," he said.
