Sydney, Aug.21 (ANI): Polls have closed on the Australian east coast with exit surveys suggesting that Labor may win in what is turning out to be an election cliffhanger.
Exit polling for Sky News suggests the Government's primary vote could have surged to 42 per cent, with the Coalition on 45 per cent and the Greens 9 per cent. A further four per cent of voters are casting their ballots for others.
The Australian reported the figures show a significantly higher primary vote for the Government after a News poll taken in the final days of the campaign had the Government's primary vote at 36.2 per cent to the Coalition's 43.4 per cent.
The exit poll, conducted by Auspoll in 30 key marginal seats, showed the two-party preferred vote went 51 per cent to Labor and 49 per cent to the Coalition.
A Nine Network exit poll of 30 marginal seats gave Labor a two-party preferred lead of 52 per cent to 48 per cent.
Centrebet took a bet of 60,000 dollars at 1.60 dollars on Prime Minister Julia Gillard's team before shortening Labor's odds to 1.39 dollars this afternoon.
The Coalition meanwhile has drifted out to 2.90 dollars, from 2.38 dollars, and punters can help themselves to 2.55 dollars for a hung parliament.
Senior Labor sources were "cautiously optimistic" the exit poll figures - if repeated in the official count - might be enough to see the government returned.
