Aussie state elections too close to call

It could be days or weeks before the governments of South Australia and Tasmania are finalised after Saturday's election outcomes were too close to call.

SA Premier Mike Rann late on Saturday night said he could not yet claim victory, while Labor in Tasmania appears to have lost its majority, with the Liberals making a claim to form a minority government.

Labor is expected to scrape over the line in South Australia, after a campaign which saw Isobel Redmond, Liberal leader for just eight months, make big gains on Mr Rann who has been premier for eight years.

At least two seats hang in the balance, but Mr Rann is likely to win a third term.

It could be up to a week before a final result is known after all postal votes are tallied.

Labor entered the election with a 10 seat majority in the 47-seat assembly, and is forecast as likely to hold 25 seats. The Liberals are expected to have 18, with four Independents.

"I hope that we have an opportunity to govern South Australia and make sure the momentum that this state has got now continues for the next four years," Mr Rann told party faithful.

Ms Redmond also refused to concede defeat on Saturday night after witnessing an eight per cent swing to her party.

In Tasmania, Liberal leader Will Hodgman has staked a claim to for a minority government after Saturday's election is likely to end in a 10-10-5 split between the Liberals, Labor and the Greens of the 25-seat assembly.

Premier David Bartlett had said that in the event of a tie between Labor and Liberal, the overall number of votes each party gains across the state would decide the dominant minority.

"It is clear that the Liberal party has the strongest number of votes and if that remains the case then I expect we would be given the opportunity, the privilege and the honour of governing this state," Mr Hodgman told the tallyroom in Hobart.

Mr Barlett and Greens leader Nick McKim said they were committed to working towards the good of Tasmania.

"No matter what Will, Nick and I agree or disagree on, I am convinced that they, like me, they are motivated by doing their bit for Tasmania and seeing the lives of Tasmanians improve," he told the tallyroom.

The final outcome of the Tasmanian election may not be known until the count is finalised by April 1.
