Crowds will pour into Grass Patch for the biennial Yabby Classic on March 14.
The community fundraiser will kick-off at 1pm with market stalls, children's activities, a cheesecake competition, licensed bar and free camping.
Yabby enthusiasts can compete in a shelling contest, the 'Yabster Challenge' foot race, win category prizes and one lucky racer will take home the coveted 'Yabby Cup'.
Committee member Sharon Smith said more than 500 people are expected to filter through the gates to join in the action.
This year, organisers have put out a call for yabbies from surrounding areas after years of dry conditions have depleted local stocks.
Mrs Smith encouraged producers from outside of the area to bring their yabbies to share and keep the event's traditions thriving.
"It has been been a very dry season with no rain and no water in the dams so no yabbies," she said.
"There's still the odd person who has water in their dams, so we will just go a bit further afield to source them.
"People who are entering the competition, we'd appreciate if they could bring along an extra bucket to share. We'd love to have enough for people to have a taste.
"We will find enough yabbies to race and we will hand pick them out a few days before and look after them."
Money raised from the event will support community projects and the Royal Flying Doctor Service.
