The Tasmanian Premier has pledged to scrap headworks charges for new developments if Labor is re-elected at next month's state poll.

Lara Giddings used the first leaders' debate to announce the $6 million policy, which matches the Liberals' pledge.

She has also announced $5 million in business grants under a re-elected Labor Government plan to create 6,000 jobs.

It comes a day after the Premier revealed the budget bottom line has deteriorated significantly since last May.

Nevertheless, Ms Giddings has told 150 business people at the debate in the Hobart, the economy had turned the corner.

"Today we have seen employment fall to 7.6 per cent, today we have seen net growth of 200 jobs, today we have seen 700 new full-time jobs created in the month of December," the Premier said.

The Opposition Leader Will Hodgman told the audience, Labor had an appalling economic record.

"The latest election the Labor Party promised 15,000 new jobs to Tasmania by 2014, in fact, Lara confidently predicted we can reach new record levels of employment in this state," he said.

"Now the reality is we have record levels of unemployment."

Political analyst Richard Eccleston says the support for the Greens in the latest EMRS poll shows Nick McKim should have been included in the leaders' debate.

"I don't think it's in the interests of the democracy or the political debate in Tasmania that a significant established political party that's attracting a vote of 20 per cent, has five current parliamentary members, is excluded from debate," he said.

An EMRS poll of 1,000 people shows 39 per cent support for the Liberals, while Labor and the Greens are on 14 and 12 per cent respectively.
