The Greens will consider overhauling the way the party is run in Tasmania amid internal criticism that it is autocratic and secretive.

The push for change has come from within the party.

Greens members will meet in Launceston next weekend for their annual state conference.

It is the first since Greens ministers were dumped from the Labor government and the party's vote slumped at the March election.

Members will be asked to consider a major party reform and debate about future involvement in minority governments.

Conference papers obtained by the ABC showed members were unhappy.

The notice of motion described the state executive as "autocratic, secretive and not properly accountable or transparent".

Proposed reforms include: Scrapping the executive and re-defining its role, structure and relationship with the political wing

"It should go because it does not reflect the grassroots philosophy of the party," it said.

Andrew Wilkie left the Greens in 2008.

"There's no doubt that the Greens have burned a number of members and a number of candidates," he said.

His experience running on the Greens Senate ticket in Tasmania was very different to standing in New South Wales.

"It's a very top-down party," he said.

"It's controlled by a very small number of autocratic party [members] and the vast majority of members have no say and they don't like that."

Greens leader Christine Milne supported a rethink of the party's structure.

"We want to make sure we actually reach out to the community the best we can and that means looking at the way we organise," she said.

To change the constitution, 10 per cent of the nearly 1,000 party members must vote on the amendment.

The debate would be conducted behind closed doors, but the conference was opened to the media for the first time last year.

The agenda made it clear they did not want public scrutiny to inhibit discussion and a significant number of people have complained of a lack of positive coverage in the past.
