Yesterday, she stuck to the message that while there were challenges, she was up to facing them and had the full support of her colleagues.

"There is no leadership challenge in the Labor Party at all and, in fact, I'm very pleased with the strength of support I have," she said.

"What my troops understand already is that we are here for the long term, we're here to make this minority government work and that we have another 2 1/2 years to go, so I don't detect any panic."

She continued to express frustration with the way that the government is perceived by the public - and reiterated her plan to keep explaining policies to people face-to-face.

However, Unions Tasmania secretary Kevin Harkins said the poll results could be interpreted as a condemnation of the government's budget cuts - and eventually spell the end of Ms Giddings's leadership.

"If the trend continues there will certainly be angst within the Parliamentary Labor Party to consider who will be leading the party at the next election," Mr Harkins said.

ALP state secretary John Dowling doesn't see any benefit in a change of leader, and believes the party is on the right track.

However, even he acknowledged that it is failing to sell its message.

"Clearly, we have to be out there engaging with the community and providing voters with a greater level of understanding about what we're trying to achieve," Mr Dowling said.

Political analysts are describing the results - which would deliver a majority Liberal government if an election was held today - as catastrophic for the ALP.

"The Labor vote has dropped 21 per cent since March 2010 ... and I'm not sure whether the party will be able to retrieve its position," Dr Tony McCall said.

His comments were reiterated by his University of Tasmania colleague Associate Professor Richard Eccleston, who said the results were so strong for the Liberals that it may shift the political debate from what the government was doing to what the opposition would do.

While Ms Giddings pointed to budget cuts and the forestry deal as primarily to blame for Labor's unpopularity, Greens leader Nick McKim acknowledged that the school closure debacle may have contributed to fewer votes for the Greens.

He refused to speculate on another leadership change within the ALP this year, and like Ms Giddings said the government was focused on getting the state back on track - not on polls.

Opposition Leader Will Hodgman - who commands a record high approval rating as leader of 52 per cent - said the poll showed that, like him, Tasmanians had no confidence in their government.

"I'm not even speculating about when an election may or may not be, other than to know it might be some time away," Mr Hodgman said.

"There's a lot of hard work to do between now and then, and we'll get on with the job."
