Tasmanian Greens Leader Cassy O'Connor is confident the party's vote will grow in Lyons, and hopes for the same in Braddon.
The Greens appear to have some chance of picking up a Lyons seat in Saturday's election.
They have former Greens MHA Tim Morris - previously a strong poller - on their Lyons ticket, which is led by social justice and forest campaigner Liz Johnstone.
"The magnificent, sprawling electorate of Lyons has been done over by the old parties, whether it be on Cambria Green on the East Coast, the prison site at Westbury or backing the privatisation of Lake Malbena in the World Heritage Area," Ms O'Connor said.
"Liz Johnstone is an engaging candidate with a massive heart for this island and its people.
"Liz puts the people in Lyons first.
"We are confident we have the candidate and the good policies, and that the Greens vote will grow in Lyons."
The Greens took 6.53 per cent of Lyons first preferences in 2018 and did not manage to gain a seat, with the Liberals getting three and Labor two.
The Greens ticket managed just 3.57 per cent of first preferences (2297 votes) in North-West and West Coast seat Braddon, which also went 3-2 to the Liberals over Labor.
Independent Craig Garland, who holds some similar views to the Greens, got 1967 first preferences.
" We are certainly hoping the Green vote will grow (in Braddon)," Ms O'Connor said.
"Dr Darren Briggs is an exceptional candidate, who would make a great MP.
"The Greens are the only party in the parliament standing up for North-West Coasters who don't want a massive salmon farm expansion along their coastline, or a wind farm on the bird haven that is Robbins Island.
"Too often we're the only ones in parliament raising these concerns.
"As an emergency doctor, GP and a tourism operator, Darren is very connected to his community.
He's been hearing a lot about the under-investment in health and housing, as well as people's fears of salmon farm expansion and the Robbins Island wind farm proposal."
Ms O'Connor - who became Leader in 2015 and is the longest serving current leader among the three established parties - said she intended to serve the full term if she was re-elected in Clark.
There has been some speculation prominent environmental campaigner Vica Bayley might be on the Clark Greens ticket to replace Ms O'Connor in parliament if she quits part-way through the next term.
"Anyone who watches parliament can see I give the job everything I've got, and I love being in there and standing up for Greens values," she said.
"It's a great honour.
"It's sensible to have a good number two on your ticket, because you never know what might happen.
"It's our insurance policy to ensure good Greens representation in parliament.
"With Vica on the ticket, I know if I was hit by a bus, for example, Clark would be in the safest of hands."
