Tasmanian Premier Will Hodgman and his Labor rival have ruled out doing deals to form minority government as the race to a March 3 poll officially begins.
Mr Hodgman on Sunday morning ended weeks of speculation by announcing the state election would be held in a little under five weeks.
The state Liberal leader warned Tasmanians of the risk of a minority government, saying he plans to govern outright or not at all.
"There is no doubt that the certainty, the stability, the common purpose, the plan that we've outlined is best delivered by majority government," he said while flanked by party faithful at a New Norfolk park north of Hobart.
"Certainly the record shows (this is) best done by Liberals."
The Liberals hold a majority of 15 seats in a 25-seat parliament but Labor under Rebecca White is expected to add several seats to their seven.
Many analysts are tipping a hung parliament that could see the balance of power fall in the hands of the Greens or the Jacqui Lambie Network.
Mr Hodgman labelled it a "crucial election", saying under the Labor-Greens minority government in 2011-14 the state's unemployment rate "skyrocketed" and jobs were lost.
He ruled out any deals with the Greens or the Jacqui Lambie Network.
Ms White says Labor will also be campaigning for a majority government.
She said health was the number one issue for many Tasmanians and will be Labor's priority if elected.
"Tasmanians deserve better than Will Hodgman and his team," Ms White said outside Royal Hobart Hospital.
"We will not do any deals with any minor parties. We will not do any deals with the Greens. And we will not govern in minority."
Ms White, who has been opposition leader for barely 12 months, brushed off suggestions her future hangs on victory at this election, declaring she was "not going anywhere".
Poker machines, housing affordability and health shape as key election issues with the parties' campaigns to ramp up from Monday.
Tasmania Greens leader Cassy O'Connor said her party has not had any discussions with either major party about forming a minority government.
It was up to Tasmanians to decide the make-up of the next parliament, she said.
"If they decide that no party should be given a majority, we'll be there working for stable government, co-operatively and constructively," she said at Bellierve.
"Minority government is government for grown-ups and majority government is for vested interests, corruption and corporate deals."
The Greens are targeting five seats, but Ms O'Connor admits it will be tough.
"It's going to be a very dynamic and fluid election, but we're ready."
Jacqui Lambie did not return calls for comment but has previously indicated her party is open to sitting down with the Liberals or Labor.
