Scrapping the five cent coin, changing the colour of ballot papers and altering Tasmania's voting system are some of items up for discussion when Tasmanian Liberals get together this weekend, joined by Prime Minister Malcolm Turnbull.

The gathering in Launceston is the first significant meeting between senior Liberals and local members since the Tasmanian branch's routing at the July federal election when all three House of Representatives MPs lost to Labor.

Members will debate motions put forward by branches from across the state. If they are passed, they will form part of the party's policy platform.

Premier Will Hodgman said it would be a "battle of ideas".

"I welcome the fact that Liberal branches across the state bring forward ideas, we appreciate the fact that members want to express views and of course there'll be arguments on either side," Mr Hodgman said.

Ballot papers bending minds: George Town East Tamar branch

The colour of ballot papers could be persuading people to vote Green, according to the George Town East Tamar branch.

They want the Australian Electoral Commission to change the colour of House of Representatives ballot papers from green because they provide "free subliminal advertising for the Greens inside polling booths", their motion stated.

The Southern Young Liberals want the Federal Government to remove the five cent coin from circulation.

"The five cent pieces are rapidly becoming irrelevant due to size," the branch motion reads.

'Marxist' agenda in Young Lib sights

The Southern Young Liberals will move to abolish the controversial Safe Schools Program, which encourages students to accept diversity.

The federally-funded program raised the ire of some right-wing MPs because of its use of educational tools about gender and sexual diversity.

The motion from the young Liberals said the program "goes beyond the anti-bullying message it was designed to portray and attempts to indoctrinate young students with notions of gender fluidity".

Tasmanian Liberal Senator Eric Abetz has supported the motion, previously stating Safe Schools was "not about bullying, it was about some sexuality agenda in the Marxist cause, and frankly mums and dads didn't want that".

Hare Clark system in focus

The Launceston City branch is gunning for the party to scrap Tasmania's electoral system known as the Hare Clark electoral system.

Named after Tasmanian Andrew Inglis Clark and Englishman Thomas Hare, the system is unique and responsible for the state's five-member electorates.

But the Launceston branch said it has resulted in "unfavourable outcomes" for the state, that had led to political instability.

Mr Hodgman has committed to not changing the system, but the branch will argue he can take the proposal to the next state election.

Mr Hodgman said he "welcomed the debate".

Dial down pokie reliance: Sandy Bay Liberals

The motion, from the region where Australia's first legal casino Wrest Point is located, referenced the ABC documentary Ka-Ching Pokie Nation, and said the machines were not a game of chance but "programmed for an inevitable outcome".

It also suggested gaming machine licences should be renewed every two or three years, rather than every 15 years, to ensure a "more manageable time period for a gradual reduction [of] the dependency".

The motion comes as the Tasmanian Liberal Party begins planning to include a "public interest test" for all new gaming machines in the state.

Water takeover doomed to fail

The Launceston Business Branch of the party will call on the State Government to take over council-owned water and sewerage company TasWater, labelling the council's management a "failure".

TasWater is attempting to raise more than $1 billion to upgrade the state's outdated infrastructure over ten years.

"Local governments are the owners of TasWater but have failed to properly manage it," the motion says. "They have neither the available resources nor will to fix the problem."

But Brighton Mayor Tony Foster warned of stormy waters ahead should the move be adopted as party policy.

"I don't think the State Government would want to enter into a fight with local government on this particular issue, but we would fight very strongly as a group of 29 councils to defend it," he said.

Mr Turnbull is set to address the party faithful in Launceston on Saturday morning.
