The way politicians are elected to the West Australian Parliament could change dramatically under a range of proposals being floated amid claims the state's electoral system is lacking in fairness and integrity.

The Greens are pushing for voting reforms designed to make it harder for tiny political parties to "game" the system and get elected to parliament with a fraction of the vote, after a similar reform was implemented for the federal Senate.

But it is not the only major change being mulled.

So what are the perceived problems with WA's electoral system and what are the suggestions to resolve them?

What do the Greens want to do?

This week Greens MP Alison Xamon will introduce legislation to remove "group voting tickets".

As things stand, when someone votes in the Upper House they have two options — put a '1' above the line for their preferred party, or number every one of dozens of candidates in order below the line.

The first of those options is the one an overwhelming majority of people choose, but it means political parties — rather than electors themselves — choose where those votes end up through often-secretive preference arrangements.

Under Ms Xamon's proposal, the existing options would be replaced.

Voters could vote above the line, picking their six most preferred parties, or below the line, selecting their 12 most preferred candidates.

Why do they want to do it?

Some political parties and experts have long been concerned by the ability of tiny parties — who get a fraction of the vote — to still end up in parliament, under the system WA uses.

At the last state election, Fluoride Free WA and the Daylight Saving Party both went close to having elected MPs despite each picking up just a few thousand votes statewide.

Micro-parties were able to achieve disproportionate success when that voting system was used in the Senate as well, most notably when Ricky Muir from the Australian Motoring Enthusiast Party got elected to a powerful crossbench position with just 0.51 per cent of the Victorian vote.

"We need to ensure we have brought back integrity to the way preferences work within our democratic system," Ms Xamon said.

"It is unacceptable and it is an indictment on our democratic system."

What other changes are also possible?

Ms Xamon's bill focuses largely on group voting tickets, but there are other criticisms about WA's voting system that could also be addressed.

A group of 12 experts from all of WA's universities recently wrote a joint letter to every WA MP, calling for a range of changes — including the group voting ticket issue Ms Xamon is trying to address.

Most critically, they also called for a total change to the way WA's Upper House is set up.

Currently there are six regions, with three of those in the city and the rest coming from the bush.

Each region elects six members, even though the population of each Perth electorate is drastically higher than each of the regional ones.

"This distorts electoral outcomes and fails the democratic fairness test as it denies Western Australians an equal say in how their state is governed," the group of 12 academics wrote.

A range of proposals have long existed to attempt to tackle this, such as giving Perth four regions to the country's two or doing away with the region system altogether and having Upper House MPs elected proportionately to their party's statewide vote.

What does the Government think about all of this?

Officially, Electoral Affairs Minister Stephen Dawson says the Government is open-minded about voting reform.

"Further opportunities for electoral reform will be considered in due course. I am happy to hear from other MPs if they think there should be other types of electoral reform," Mr Dawson said, noting that Labor was pursuing changes designed to improve transparency around political donations.

But Labor has long wanted to reform the Upper House and that desire only increased after the last election, when it felt like it was badly short-changed.

Despite an electoral rout in the Lower House, Labor picked up just 14 of 36 seats in the Legislative Council.

It is believed the Government wants to achieve 'one-vote, one-value' reforms — or something close to it — for the Upper House, if it can convince enough MPs to support it.

What about the other parties?

Both the Nationals and some other regional MPs are vehemently opposed to any changes that would reduce the number of politicians representing the bush.

"We would do everything in our power to stop this so-called reform that would benefit the major parties and hurt regional WA," Nationals MP Vince Catania said.

On the Greens' push for group voting tickets, most parties are still weighing up how they feel about that — although Opposition Leader Mike Nahan said he was not a supporter.

But when that reform went to the Senate, the Liberals, Nationals and Greens all voted in favour to pass that bill while Labor was opposed.

The change could not pass in WA without Labor's support.
