Federal Opposition Leader Tony Abbott says Julia Gillard's reconfirmation as prime minister is a stay of execution, rather than a new start for Labor.
Ms Gillard on Monday won the ballot against Kevin Rudd, 71 votes to 31.
Mr Abbott said there were still 31 members of caucus who did not have confidence in Ms Gillard.
"What I think today is likely to be is not so much a new start for this prime minister but merely a stay of execution," he told reporters in Canberra.
Mr Abbott said there would still be Labor's carbon tax, "border protection chaos" and not enough focus on the jobs of Australian workers.

While Ms Gillard was saying a good government had been dragged down by a wrecker, Mr Abbott said it was more likely people would see a bad government exposed by a whistleblower.
"The public will not quickly forget Kevin Rudd's critique that this was a government that was run by faceless men," he told journalists in Canberra.
"That this is a government which is actually damaging our country and that this is a government led by someone who has fundamentally forfeited the trust of the Australian people."
Mr Abbott says the coalition has a plan to build stronger communities.
"We are going to give more people-power to schools, to hospitals," he said.
He said the coalition also had a plan for a cleaner environment based on "real action, not on a great big new tax".
Mr Abbott says the coalition also has a plan for strong borders.
"We know we can protect our borders with policies that worked, and it is only the stubbornness of this prime minister that prevents those policies from being put in place," he said.
Mr Abbott renewed his call for an early federal election.
"The clear answer from today is that the only way we can get real change is with an election," he said.
"The prime minister should be chosen by the people - not the faceless men."
Asked if he would move a no confidence motion against the government, Mr Abbott remained uncommitted.
"I have no confidence in this prime minister," he replied.
Another 31 members of Ms Gillard's own caucus also had no confidence in her, he said.
"The challenge is to get some of them, and to get some of the independents, to actually vote that way in the parliament," he said.
Mr Abbott said his reputation for being negative, because he constantly rejected the government's policies, was not deserved.
"I am a model of positivity compared to the kinds of vitriol, the kinds of destructive criticisms that Labor members of parliament have been making of each other," he said.
