If Pauline Hanson wins a seat in the Senate, the Greens will be waiting to show One Nation's leader there is no place in modern Australia for racist, bigoted views.

Greens leader Richard Di Natale says the party will stand up to Ms Hanson, who looks set to return to federal parliament in a Queensland Senate seat.

"We will take it right up to her, to show that in a modern Australia there is no place for racism, there is no place for bigotry, for the sort of hatred that she is spreading through her views," the senator told reporters in Melbourne on Sunday.

"We won't roll over like (former prime minister) John Howard did when Pauline Hanson first came on to the political scene federally."

The Greens leader says a multiparty government is still a live option with the election too close to call.

He said the Greens might need to have talks with Labor in coming days.

But Labor leader Bill Shorten later ruled out his party forming any coalition or entering into an agreement with the Greens.

Senator Di Natale won't be making a deal with the Turnbull government, citing its record on climate change and asylum seekers.

"It has an appalling record on all those things, and it is inconceivable we could sit down and form any sort of co-operative government with the coalition," he said.

He says the election results show the Greens have cemented the foundations for the party, and become a powerhouse in Victoria.

Adam Bandt retained Melbourne and Alex Bhathal could claim Batman from sitting Labor MP David Feeney - whose campaign got off to a negative start when it was revealed he hadn't declared a $2.3 million property.

The Greens' Stephanie Hodgins-May has an outside chance at Melbourne Ports.

"It is only a matter of time before seats like Higgins, Kooyong, Wentworth could turn Green," Senator Di Natale said.

The Greens believe they may get a second Queensland senator, although Robert Simm in South Australia looks set to fall.
