Opposition leader Bill Shorten says Labor will form government in its own right if it wins the federal election.
Bill Shorten has a simple message for the Greens - they're dreaming if they think Labor will form a coalition government with them in a hung parliament.
Greens MP Adam Bandt has raised the prospect of a Labor/Greens coalition, saying his party would be "up for it".
The Labor leader's response was blunt, telling ABC radio in Townsville on Tuesday: "He's dreaming."
Labor was fighting the election to form government in its own right.
"Labor will not be going into coalition with any party," Mr Shorten said.
Mr Bandt said Labor's refusal to negotiate would be "pig-headed".
With opinion polls showing Labor would struggle to win an absolute majority in parliament's lower house, voters were entitled to know what the Greens would do in that situation, he said.
Greens leader Richard Di Natale said it was inconceivable his party would do a deal with the coalition.
Mr Shorten says splitting the progressive vote would be the worst result for working people.
