Counting is underway in Tasmania amid Newspoll predictions of a hung parliament.

The Greens look set to hold the balance of power in the state with neither of the major parties in a position to rule in its own right.

But both Premier David Bartlett and Liberal Leader Will Hodgman have said they will not cut a deal with the Greens.

Mr Bartlett says he will stand aside as Premier if Labor and the Liberals win the same number of seats, but the Liberals secure more of the popular vote than his party.

Despite the polling Mr Bartlett remained upbeat as he cast his vote this morning at a Hobart primary school in the southern Tasmanian seat of Denison.

“I’m a born optimist and I believe that when Tasmanians get into the ballot box today they will be thinking very carefully about setting the priority for the next four years,” he said.

Some opinion polls have indicated many Tasmanians still have not decided how they will vote.

The latest Newspoll shows a hung parliament is the most likely outcome, with Labor and the Liberals taking 10 seats each and the Greens holding the balance of power with five.

Mr Hodgman cast his ballot paper at a community hall in Margate in the southern electorate of Franklin.

He says he is satisfied with the way the Liberals have run their pitch for government, and is happy with his party’s decision to steer clear of negative campaigning.

McKim pleased

Greens leader Nick McKim, whose Newspoll satisfaction rating of 58 per cent is higher than the Liberal Leader and the Premier, has reiterated his pledge to work with either party in the event of a minority government.

“We’ve had a very good response on the ground and on the street in this campaign,” he said.

“Ultimately I think that’s because Green values are mainstream values and they see us as a safe pair of hands for Tasmania’s future.”

Mr Hodgman praised the performance of his team during Tasmania’s five-week election campaign, saying his campaign team has been cohesive and disciplined.

“I’d happily go round again but I wouldn’t change a thing. We’ve been positive, we’ve been constructive, our team of candidates have been fantastic,” he said.

Mr Bartlett says gets the feeling the momentum has picked up for Labor. “Look I’m pleased. I’ve really enjoyed the campaign I’ve got to say,” he said.

“There’s nothing more invigorating for me personally than being out and about and talking to the people of Tasmania and hearing directly from them what’s going on in their lives, I’ve really enjoyed that.”
