Former Victorian premier Denis Napthine has revealed Labor rejected a plan to transform voting for the state's Upper House.

A collection of minor and micro parties are set to control the Legislative Council after last month's election.

The Andrews Government would likely need the support of groups including the Sex Party, Shooters and Fishers, and Democratic Labour to pass legislation.

Dr Napthine said he phoned Daniel Andrews, then the opposition leader, around six months ago proposing two models which would have dramatically altered voting for the house of review.

The first idea would have seen candidates only elected if they won at least 5 per cent of the first preference vote.

The other suggestion would have allowed preferential voting above the line, crushing the influence of the so-called preference whisperers, according to Dr Napthine.

The former premier said Mr Andrews expressed interest but said Labor was not interested in another call a fortnight later.

Lacking bipartisan support, the Coalition did not introduce any legislation.

The Government declined to comment when contacted by the ABC.

"To have people elected to the Upper House, either the Senate or the Legislative Council with 1 per cent, 1.5 per cent or even less than 1 per cent of the primary vote, to me, is not a true reflection of the way our democracy should work," Dr Napthine said.

"I believe there should be some process where there is a minimum requirement of at least 5 per cent and I would urge all parliaments to give that serious consideration."

Victorian Motoring Enthusiast Senator Ricky Muir was elected to the Senate at the 2013 federal election after claiming 0.5 per cent of first preference votes.

South Australian Family First Senator Bob Day claimed 3.76 per cent of first preferences.

Dr Napthine urged parliaments nationwide to consider Upper House reform.

"You would have a system that their preferences would all be counted irrespective of how many [first preference] votes they got," he said.

"You can still have successful minor parties, but they need to have a modicum of support across the community."

The Victorian Electoral Commission said final Legislative Council results would be released on 17 December.
