While it will almost certainly be a two-way contest between Bass Labor MHR Ross Hart and Liberal candidate Bridget Archer on Saturday night, four other minor party candidates and an independent are also pinning their hopes on winning the seat.

There's Carl Cooper of the National Party, Tom Hall of the Greens, Allan Roark of the United Australia Party, Susan Woodbury of the Animal Justice Party and independent Todd Lambert.

Mr Cooper, a Hobart-born pharmacist and a farmer, said farmers in Tasmania were feeling "pretty positive" due to the state reaching "a real tipping point in terms of how agriculture is seen" here.

He said the nation would have to distance itself from coal-fired power "over time".

"You can't run agricultural concerns without understanding and being sensitive to climate," he said.

In terms of the Nationals' preference deal with One Nation, Mr Cooper said he'd prefer to distance himself from "some of the policies" of the far-right party.

"We as candidates don't necessarily have a lot of direct involvement in those [preferencing] decisions," he said.

Mr Hall, an anaesthetist at the Launceston General Hospital, said the Greens' ultimate goal in Tasmania this election was "to get [Senator] Nick McKim re-elected".

"Up here, I think our visibility's been pretty good," he said. "We got the corflute posters out fairly quickly.

"There's a couple on most people's commute to work."

Mr Hall said he'd be happy if he received more than 12 per cent of the primary vote.

"If I get less than 10 per cent, I'd be pretty disappointed," he said.

Meanwhile, Mr Roark, who is a motor racing identity in the North, said he chose to run for billionaire Clive Palmer's United Australia party "on a policy basis, not a personality basis".

"We've got a marketing campaign that we've stuck to," he said. "It's up to the candidates to do the work at the coal-face."

Mr Roark said he found his experience campaigning to be "educational and enlightening".

"A lot of people [I've spoken to] have some great ideas on how to solve the problems that we have out there," he said.

"I've had a lot of encouragement from people I don't even know."

Ms Woodbury formerly worked at the RSPCA and said "a lot of the [other] parties aren't particularly friendly towards the Animal Justice Party".

"I've been really surprised by the number of people who understand the animal cruelty issues and the climate issues and how they're linked," she said.

"When I see statements from [Prime Minister] Scott Morrison calling activists like me terrorists and [Agriculture Minister] David Littleproud ... talking about Australia having the best animal welfare laws in the world, it just really annoys me.

"But the thing that I find most annoying is that they never talk about the fact that intensive animal agriculture - the intensive factory farming, fisheries and deforestation - is up there with coal as far as affecting climate change."

Mr Lambert is a recreational fisher with a trade union background who is notable for having spoken up about the issue of supertrawlers in Tasmanian waters.

His wife, Janet, unsuccessfully ran as a Labor candidate for Lyons in the 2018 state election, as well as for the Legislative Council seat of Prosser later that year. Ms Lambert is an adviser to Lyons Labor MHR Brian Mitchell.

"[Janet] does her thing, I do mine," Mr Lambert said. "It's a little bit awkward sometimes."

Mr Lambert described his politics as being "a shade left of centre".

"I have views that align with both sides of politics," he said.
