Mission Rebuild - Australia's Biggest Working Bee aims to gather as many volunteers, materials and equipment as possible in Corryong between March 6 and 9.

Two similar projects are also planned for East Gippsland and the NSW South Coast at the same time.

Organised by recovery campaigns Fencing for Fires and Tradies for Fire-Affected Communities, the initiative is receiving logistical support from Deloitte Australia.

Fencing for Fire's Jamie Wolf, of Indigo Valley, said his visits to the Upper Murray highlighted the need for more "feet on the ground".

"It just popped in my head ... like at a footy club, you'd have a working bee," he said.

"The guys are so resilient up there, but going around you can just see in their eyes the enormity of the task.

"They know what they've got to do, they've started doing it, but ... we want to help them recover quickly rather than waiting two to three years down the track before they've got a boundary in place or all their paddocks are back up.

"It's about making the biggest impact in the shortest amount of time."

Jobs to be allocated each day would include basic repairs, fencing and replanting, with both manual labour and specialised skills required.

A campsite for workers is being organised.

"People can stay where they like, but the idea is each morning we meet as a group," Mr Wolf said.

"It's about injecting money into these communities as well."

Mr Wolf approached Deloitte Foundation director Pete Williams, whom he'd met in Cudgewa last month, about the working bee.

Mr Williams said Deloitte had seconded people to assist these community campaigns in aspects like building websites, promotion, co-ordination and sponsorship.

"One of the reasons we really wanted to help was that we just saw the impact that the grassroots organisations were having," he said.

"There's a lot of vagueness out there as to what the recovery process is and how it's going to work.

"But just to see these people out there on the ground saying, 'How can we help? Let's get out and do stuff for you'.

"We just wanted to really help them scale up and make things work because we felt they were having the most direct impact on bushfire-affected people."

"So many have inquired about helping - this is their opportunity," Mr Wolf said.

"And if you can't attend there's always the option to donate to the page."
