It's not yet clear whether Labor or the Liberals will end up with the most seats, or who will form a government with the help of the crossbenches.
Independent Andrew Wilkie, who is tussling with Labor for the lineball Tasmanian seat of Denison, said it was not true he would automatically support Labor.
"I've got a clean sheet of paper in front of me at the moment," the left-leaning Mr Wilkie told ABC Television on Monday night.
He said that, if elected, he would side with the party best placed to offer "stable, competent and ethical government" - not necessarily the party with the most seats.
"In the acts of lying and so on, I won't accept that and I won't support legislation in that regard," he said.
Another potential kingmaker, West Australian National Tony Crook, is counted as a coalition member but has said he'd act as an independent.
"If we need to step outside of the coalition, we're prepared to do that, and if we need to step outside of the party room we'll do the same thing," Mr Crook told ABC Television.
When asked if he would sign up to a deal with the coalition and support them on all laws, Mr Crook said: "Not at all".
The WA Nationals were an independent political party, he said.
Another kingmaker MP, the Greens' Adam Bandt, said he would meet other independents in Canberra on Tuesday to get to know them.
He told ABC Television he was inclined to support Labor because they were more progressive, and flagged that he would move in the House of Representatives on gay marriage, asylum seekers, and putting a price on carbon.
