The Tradies for Fire Affected Communities group is another example of widespread generosity in response to the blazes that have burnt nearly 11 million hectares across the country.

Set up on 2 January with the humble expectation of reaching "50 or 60 people", TFFAC now has thousands willing to invest their skills and time.

Help given by group members has so far ranged from delivering pallets of feed for fire-affected animals to convincing a company to donate sprinkler systems they helped install.

Have you ever wondered about Aussie mateship and Aussie spirit? Here is your answer.

Australia's tradies are banding together to help rebuild the homes and lives of the state’s bushfire-ravaged communities.

Sparkies, chippies and plumbers from the fire fronts to Melbourne are signing up en masse to help in the effort, which in just a week has drawn more than 9000 tradies and other volunteers offering to work for free.

'Tradies for Fire Affected Communities' is a group of volunteer tradesmen and women from across Australia who are looking to play their part in repairing homes and helping those in need.

The group has almost 4000 registered tradies and more than 5000 volunteers, who range in age from 18 to 60.

The group was started by 31 year-old Melbourne-based carpenter Piers Smart. “I was at home trying to think of ways I could help and unfortunately financially I was unable to. But I could offer my weekends as a chippy going up and helping with clearing or rebuilding,” he said.

Group founder Piers Smart told AAP he was nervous when he first shared it with his community, fearing no one would sign up.

"But then a very popular Instagram page shared my initiative and it blew up. Seeing more than 4000 tradies join was outstanding and really special."

Mr Smart, 31, had spent New Year's Eve waiting on updates from his father, who had been caught up in a bushfire ravaging the northeast Victorian town of Corryong.

His dad was evacuated but the experience touched the Melbourne carpenter, who decided to use his trade skills to benefit bushfire victims through the reach of social media.

Mr Smart created the group before going to bed and shared a post.

"For anyone that's keen to help out, I've just started a little group. For any tradie out there that can offer their time, please join," it read.

Three days later the group had already attracted almost 5000 members.

"I am still managing the group but there's a few people helping me out. Friends of mine but also people from different professional backgrounds volunteering their time to roll this out effectively," Mr Smart said.

"We all have full-time jobs and do this in our free time."

Mr Smart said they try to send tradies only when they will not interfere with emergency services work.

"We don't want to be cowboys and get into people's ways or put our tradies in danger," he said.

The group has now started a website which aims to provide long-term help.

The plan is to continue operating as a meeting point for those seeking fire relief while calling on businesses to lend their support to rebuilding communities.

"There's going to be work to do for months, if not years," Mr Smart said.

"We want to be out there for the long term, not only while it's on the news and everyone is thinking about it."
