Labor's Left faction has vowed not to give up its fight against uranium exports to India, after the ALP national conference endorsed the Prime Minister's plan to lift the ban.

The Federal Government is now preparing to negotiate an agreement with India to export Australian uranium to the country, a move which Julia Gillard says will boost trade and enhance Australia's relationship with India.

"We are at the right time in the history of the world to seize a new era of opportunity in this, the Asian century," she said.

"We need to make sure that across our regions we have the strongest possible relationships we can, including with the world's largest democracy, India."

But the move was fiercely opposed by several ministers and delegates who believe it is dangerous because India has not signed the Nuclear Non-Proliferation Treaty.

Labor Senator Doug Cameron says there is no way Australia can get India to agree to proper safeguards.

"There is absolutely no way we can get these commitments that the Prime Minister is talking about," he said.

"If Bush couldn't do it, if the Canadians couldn't do it, I don't think we can."

Senator Cameron says he will not give up the fight.

"I think this is one of the worst decisions the Labor Party has ever made in my time in the Labor Party," he said.

"I'll be watching very closely about what we actually do in terms of getting commitments from the Indian Government."

Speaking before the conference, frontbencher Peter Garrett also said it is too dangerous to sell to India.

Federal Infrastructure Minister Anthony Albanese says it is inappropriate.

"It is the case that nine months after the Fukushima nuclear disaster is not the time to be expanding our uranium exports," he said.

But delegates endorsed Ms Gillard's view with 206 voting in favour and 185 opposing it.

As MPs spoke, a group of about 10 anti-uranium protesters were chanting in the gallery.

One man was removed for being overly rowdy.

Domino effect

The Australian Conservation Foundation (ACF) has also condemned the decision to sell uranium to India.

ACF nuclear campaigner Dave Sweeney says exporting uranium to a country that is not a signatory to the non-proliferation treaty will undermine Australia's credibility and reputation on nuclear issues.

"It's only a matter of time before the pressure mounts within the ALP to 'oh, we export uranium, why don't we enrich it'," he said.

"And then it's 'we export uranium and enrich uranium, why don't we take back the waste and that will be custodianship and we'll be a responsible country and a good steward'.

"And then it'll be 'we do this, we do that to other countries that use nuclear power why don't we use nuclear power'."

But Opposition Leader Tony Abbott says Ms Gillard should have moved sooner to allow uranium exports to India.

"What she's trying to do is un-stuff a stuff-up," he said.

"The Howard Government wanted to sell uranium to India.

"One of the first things that the Labor Government did was reverse that and slap a ban on selling uranium to India and, as Prime Minister, she's trying to correct the mistake she made as deputy prime minister."

Australia currently exports uranium to China, Japan, Taiwan and the United States.

Howard policies

Meanwhile, Greens leader Bob Brown is predicting a surge in support for his party as disillusioned ALP supporters turn to the Greens.

Senator Brown says Labor's national conference has seen a number of policy changes that have meant the party has never been further to the conservative right side of politics.

He says the party's traditional progressive platform is being undermined by the leadership.

"We've got Julia Gillard as Prime Minister endorsing time after time the policies of John Howard as prime minister," he said.

"We're seeing here a historic divide between progressive and conservative politics and Julia Gillard and senior members of her leadership have moved to conservative."
