Bob Katter, Tony Windsor and Rob Oakeshott will put the finishing touches on a roadmap to power on Wednesday, before talks with Prime Minister Julia Gillard and Opposition Leader Tony Abbott.
But independent Andrew Wilkie, who looks likely to win the Tasmanian seat of Denison, says he has "quite deliberately" stayed out of the discussions.
"I'm a little uncomfortable with the way the three incumbent independents are apparently acting as one, as a bloc," he told ABC Television.
The three appear like a "political party with three factions", says Mr Wilkie, who has talked to both Mr Abbott and Ms Gillard, but is yet to favour either.
Mr Windsor told ABC Television the independents weren't acting as a bloc, but were sorting out early issues together.
"I'll talk to anybody that can help resolve this particular issue, but there's no voting bloc intended by the three of us talking," he said.
Mr Abbott tried to get on the same page as the independents by promising a "kinder, gentler" parliament.
A coalition briefing paper obtained by ABC Online reveals Mr Abbott would give independents the chance to debate and vote on private member's bills, and would give independent backbenchers an extra question time each week, and a new time limit on answers.
But it got a dubious response from Mr Windsor.
He said it was a coalition government that changed standing orders to stop independents speaking on matters of public importance.
"People think, oh well, the independents, that's code for parliamentary reform, let's put something in front of them and that will suffice," he said.
Meantime a report has surfaced that Mr Katter threatened to kill Liberal National Party MP Peter Lindsay during a heated argument at Townsville Airport in May.
An Australian Federal Police spokeswoman told AAP that Mr Lindsay, who retired from the north Queensland seat of Herbert at the election, did speak to police on May 30 but no formal complaint was made.
Mr Katter has laughed off the report as "absolute rubbish".
He, Mr Windsor and Mr Oakeshott may reveal more about their intentions in a panel discussion at the National Press Club on Wednesday with new Australian Greens MP Adam Bandt.
After the talks with the leaders on Wednesday, the trio of independents do not plan to meet again until next week, when the final result of the election is known.
