Greens leader Richard Di Natale has ruled out a partnership with the Liberal Party on voting preferences, labelling the Turnbull Government "one of the worst administrations in the nation's history".
Victorian Liberals this week raised the possibility of a "loose arrangement" with the Greens that would see Liberal preferences flow to the progressive left-wing party ahead of Labor, according to Fairfax Media.
The reported deal would result in Victorian Liberals preferencing the Greens ahead of Labor in some inner-city seats in return for the Greens "running open tickets" and not directing preferences.
Speaking on Saturday, Senator Di Natale quashed speculation of a potential Liberal-Greens deal.
"This government, this administration has been, I think, when the history books are written, (is) one of the worst administrations in the nation's history," he told ABC television.
"We won't do anything that supports this Liberal Party."
The comments follow an interview Di Natale gave to GQ magazine this week in which he addressed a possible preference deal with the Liberals, controversial senate voting changes and his thoughts on Malcolm Turnbull.
In the interview, the former doctor said there was much more chance that the Greens would govern in a future coalition with Labor than the Liberals.
There is still no firm date for the upcoming federal election, which is likely to take place in August, September or October.
