Tasmanian Labor leader Dean Winter says a no-confidence motion will be moved in the Liberal government when parliament returns on August 19.
Jeremy Rockliff was reappointed as premier on Wednesday morning, after requesting that the Tasmanian governor recommission his government.
Neither the Liberals, nor Labor, won enough seats to form a majority government in the July 19 state election.
Both major parties fell short of the 18 needed to control the lower house, with the Liberals winning 14 seats to Labor's 10 — the same as before the election.
As part of her reason for reappointing Mr Rockliff as premier, Governor Barbara Baker AC said "it is better for confidence to be determined inside and not outside the parliament".
Governor Baker said parliament will be recalled to sit on August 19 — one month on from the state election.
On Wednesday afternoon, Mr Winter confirmed a no-confidence motion would be moved.
"Whether it's by us or an independent, there'll be a motion moved in parliament of no-confidence in the Liberals and confidence in a Labor government," Mr Winter said.
[tas-election_full-results-embed]Mr Winter said he would meet with all independent members of the crossbench on Thursday to outline "the way we think this parliament should work".
"I'll speak to every member of the Tasmanian parliament, whether they're Liberals, Greens, independents, or the SFF — we need to speak with every member," he said.
It comes after Mr Winter repeatedly said Labor would not hold any discussions or do deals with the Greens.
"I understand that Jeremy Rockliff is saying he's going to refuse supply and confidence from the Greens," he said.
"The Greens will make their own decisions about the way that they approach the next parliament."
Mr Rockliff and his cabinet will be sworn in at a ceremony at Government House early next week.
Motion won't 'result in another election', Labor says
Mr Winter's decision to move a no-confidence motion in the Liberal government comes two months after he moved a no-confidence motion in Mr Rockliff, which triggered an early election.
"Tasmanians can be assured that any motion we move will not result in another election, it will result in either a Liberal government or a Labor government," Mr Winter said on Wednesday.
This year's election, held on July 19, resulted in a hung parliament with the Liberals winning 14 seats, Labor 10, the Greens five, independent MPs also winning five and one seat going to the Shooters, Fishers and Farmers party.
The state election was the fourth one held in seven years. It was also the second early election in a row to elect a minority government.
