Australia's kingmaker MPs have said they will announce today who they will back but warned, despite plans to vote as a bloc, they could still split and deliver a deadlock.

Labor leader Julia Gillard needs the support of two of the three rural independents Tony Windsor, Bob Katter and Rob Oakeshott to remain Prime Minister.

Tony Abbott needs all three to get his coalition into office.

Windsor and Oakeshott said the trio was likely to vote as a bloc, although Windsor warned there was a risk the three could still split.

Several newspapers yesterday also said unnamed conservatives were expecting Gillard to win over at least two independents to form a minority government holding 76 seats.

Bookmakers are also tipping a Gillard Labor government.

Meanwhile, a poll in the Daily Telegraph newspaper showed 56 per cent of Australians now wanted another election, regardless of which party the independents decided to back, underscoring expectations that any new government will struggle to overcome ongoing instability with such a thin majority.

The ABC reports that Gillard is expected to inform the Governor General today on whether Labour will form the next Australian government or Tony Abbot will lead the country with the coalition.
