Greens leader Adam Bandt believes the upcoming federal election will end in a hung parliament, handing his party the balance of power to push through its proposed dental care plan.
Speaking on ABC radio on Wednesday, Mr Bandt said a majority was not likely in either the House of Representatives or the Senate, paving the way for his minority party to step in.
"The Greens are on track to be the biggest third party in the Senate ever, and in the lower house," he said.
