Jacqui Lambie says the Tasmanian government and opposition's refusal to negotiate with minor parties in the event of a hung parliament is a "slap in the face" to voters.
The first day of a five-week state election campaign began in earnest on Monday with the incumbent Liberals trumpeting jobs and Labor spruiking their health policy.
Both major parties have ruled out making deals with minor parties, like the Jacqui Lambie Network (JLN), if they don't get the numbers to form a majority government.
Ms Lambie, who has remained leader of the JLN after losing her Senate spot, is running 12 candidates at the March 3 poll.
She said the JLN would keep their door open to discussions.
"What are they doing in politics if they can't adapt?" she said of the Liberal and Labor parties.
"It's just stupidity, Tasmanian people aren't falling for it. It's a slap in the face."
The Liberals have a majority of 15 seats in a 25-seat parliament but Labor is tipped to add several seats to its total of seven, while the Greens hold three.
Analysts believe a hung parliament is likely, potentially placing the balance of power in the hands of the Greens or the JLN.
Treasurer Peter Gutwein on Monday reiterated party rhetoric that only the Liberals could win the 13 seats needed to form majority.
"The Liberal Party is planning to have a majority. We are the only party that can form majority," he said.
Mr Gutwein visited a work site at Clarendon Vale east of Hobart to announce a re-elected Liberal government would reduce payroll tax for small and medium businesses.
The move would cost Tasmania's bottom line $8 million a year but create thousands of jobs, he said.
Mr Hodgman was further north in Launceston, where he promised to decentralise the Department of Primary Industries, Parks, Water and Environment (DPIPWE) by shifting 100 positions to Launceston and Devonport.
"It is important to move the department to where it can be best utilised by those who need and use it the most, our rural communities," he said.
The Greens hit out at the proposal, saying DPIPWE needs extra funding to ward off biosecurity breaches and maintain the state's clean brand.
Labor's Rebecca White trekked to Tullah on the west coast where she unveiled plans for a two-year free bus trial to help remote patients visit hospital.
She also ruled out making deals with minor parties.
"A vote for Labor is a vote for Labor," Ms White told reporters.
Labor has declared health their number one priority, with a comprehensive policy announcement expected this week.
