North Queensland independent MP Bob Katter says he will back the Coalition to form minority government.
Australia's two-and-a-half week wait to find out who will be ruling the country is almost over.
Independent MPs Rob Oakeshott and Tony Windsor are expected to announce who they are backing to form government at 3:00pm today.
This bring the Coalition and Labor both to 74 seats each.
Decision soon
Earlier today, Mr Windsor said he and his fellow independents still had not made a final decision on whether to go with Labor or the Coalition.
"We are waiting on some final documents back from both leaders, I think about nine o'clock this morning," he told ABC Radio.
"Then the three of us will get together and talk it through."
Mr Windsor told reporters that he has not let anyone in on which way he is leaning - not even his wife.
"She can't be trusted," he joked.
Parliamentary reform deal
The trio of disaffected Nationals banded together to seek information from the major parties and struck a deal with Labor and the Coalition on parliamentary reforms late on Monday.
But there was one last stumbling block to a final decision - whether West Australian MP Tony Crook and the WA Nationals had a formal agreement on confidence and supply with Opposition Leader Tony Abbott.
Mr Crook said in a statement to AAP early on Monday evening he would support the coalition, but he would sit on the cross-benches.
Crook wants the Liberals to match WA's royalties for regions scheme with federal funding for regional infrastructure.
Crook's is same tactic the WA Nationals employed to hand the Liberals power in 2008 after a hung parliament in the state.
More formal undertaking
But Mr Oakeshott's office still wanted a more formal undertaking late on Monday night.
Mr Katter was unapologetic for trying to get the best deal for his constituents.
"I've made up my mind that you give me that and you'll get the gong as prime minister of Australia, and if you don't, you won't," he told ABC television on Monday.
He paid Labor a compliment, saying under Kevin Rudd it had set about establishing the national broadband and energy grid schemes without worrying about winning votes.
Taking time
Liberal senator Nick Minchin said he did not blame the independents for taking their time to come to a decision.
Senator Minchin said Mr Abbott had run the most successful opposition campaign in more than 70 years to put a first term government at risk of losing.
It would probably be another 40 years before the scenario was repeated, he said.
