There is concern competition, rising operation costs and red tape are threatening agricultural shows around Tasmania.
This year's 105th Devonport Show in the state's north-west could be the last if about $25,000 in sponsorship is not found.
Show Society President Lesley Young says the situation is dire.
"Our general costs have gone up, the costs of security the hiring of marquees, advertising; all of those costs have gone up," she said.
"It's very, very dire. If we don't get some sponsorship this year I would think it could end up being the last year.
"We've struggled the last three years to keep the show going and I just don't think that economically we can keep doing, try to do what we've been doing."
Chief Executive of the Royal Agriculture Society Scott Gadd says traditional shows around the state are battling for support.
He says attendances have been steady over the years but red tape is causing problems.
"Things like waste management, you have to bring in extra toilets, the costs do add up just to meet what is essentially legislative requirements just to put on a public event."
A decision on the Devonport Show will be made in a couple of months.
