The Rotary Club of Hall, which owns and manages the market, has launched the Farmers Market Community Bushfire Appeal. Rotary has already donated an incredible $50,000 to kick off the appeal.

The markets, at Exhibition Park in Canberra, open at 7.30am on Saturday.

Markets manager Sarah Power said many of the market's stallholders had been severely affected by the bushfires across several regions, with "many experiencing partial or total destruction of property, equipment, crops and stocks".

"Up until now, the most significant impact on our many farmers and producers, has been drought. Now you add these devastating fires to the mix, it is just heartbreaking," she said.

"These families have been affected very badly, and we will see a knock-on affect for years to come in terms of long-term production."

Sarah said the best way Canberrans could support the stallholders was through buying and donating.

"You can support our stallholders by buying what produce there is available. These people's livelihoods depend on this income - we know many Canberrans have been feeling hopeless, so one way to show support is to continue to shop local," she said.

Rotary Club of Hall spokesman Tony Hall said the money from the appeal would go to help stallholders.

"Our appeal will assist our farmers market families with critical short-term support and assistance," he said.

"Rotary will assist fire affected stallholders and their families with financial contributions, clean up assistance, provision of new or used equipment, mental and social support and administrative support for businesses."

Visitors to the Capital Region Farmers Market can head to the Rotary Bushfire Marquee onsite at the front of the market's shed to make donations. The Farmers Market Community Bushfire Appeal will run for the remainder of January.
