Prime Minister Kevin Rudd says Labor won't enter into any agreements to form minority government if the election is tied.
Opposition Leader Tony Abbott has long ruled out any deals in the event of a hung parliament, and Mr Rudd has now followed suit.
"My ambition ... is that we are returned as a majority government," Mr Rudd told reporters in Cairns on Wednesday.
"That is the best thing for the nation.
"We will not be entering into any coalition agreements, we won't be having any negotiated agreements, we won't have any deals with any independents or any minor party."

Mr Rudd was talking after Mr Abbott announced he had instructed the Liberal Party to preference the Australian Greens last in every lower house electorate.
But he would not be drawn on preference deals, saying it was a matter for the ALP national secretary.
"Frankly, I intend to just leave it all to them."
