WA Labor has secured its third thumping election win in succession, with Roger Cook winning his first election as premier. 

The ABC's election guru Antony Green declared it a "disastrous" night for the Liberal party. 

It was also a tough night for the WA Electoral Commission, with widespread reports of long queues at polling stations and missing ballot papers at some. 

The seat of Churchlands was won, in a much tighter race than predicted, by City of Perth Lord Mayor and media personality Basil Zempilas. 

And the Greens bounced back from their poor showing in 2021 with a performance their leader believes will give them the balance of power in the next parliament.

We'll be back tomorrow with more detailed coverage of the WA election results.

Until then, thank you all for joining us, and goodnight.

Election guru Antony Green says a significant trend of the election has been the Greens recovery.

“A forgotten thing about the last election was that the Green vote did really badly," Green said. 

"The Greens lost a lot of votes to Labor in that swing.

“Some of that seems to be going back.”

At the last state election in 2021, the total vote for the Greens and minor parties, including independent candidates, was very low considering the record number of options outside of the two major parties at the time.

This election’s swings towards the Greens and independents have also resulted in a large portion of preferences flowing to Labor in seats like Churchlands and Nedlands.

There are still a couple more key seats in play this evening, let’s take a look at where they stand. 

In Fremantle, it’s looking like a tight battle between Independent candidate and incumbent Labor MP Simone McGurk.

There’s been a big swing against Ms McGurk, with Ms Hulett being the beneficiary. 

Meanwhile, in the state’s south, the seat of Warren-Blackwood is also on a knife edge. 

Labor previously held the seat with a margin of 2.2 per cent.

WA Greens leader Brad Pettitt says his party has received its “highest ever vote” at a state election.

“As a result of that, we are highly likely based on numbers that we can see, to have the balance of power at the next parliament,” he said.

Mr Pettit said the swings towards the Greens and independents were a result of changing sentiments among voters.

“Both the Greens and the independents have been talking very loud about a couple of key issues, and climate is central to that,” he said.

“I think it’s a really big wake up call for Labor.”

Albany is another key regional seat where the final result is unlikely to be known for some time.

The seat has drawn significant attention due to Liberal candidate Thomas Brough’s controversial comments on the LGBTQI community and abortion.

Dr Brough was initially expected to be in a two-way race with Labor’s Rebecca Stephens, but a late surge in votes for Nationals candidate Scott Leary has guaranteed a three-way contest.

Ms Stevens said Dr Brough’s candidacy could be a factor in the swing towards Mr Leary.

“Scott Leary … is a really well-known local guy in the community,” she said.

“I think it could be a protest vote against the candidate they’ve chosen for the Liberal Party, who has come out with some pretty bizarre comments.

“It might be a protest against the Liberal Party and we’ll see that in the results.”

From Benjamin Gubana in the ABC TV studio:

Election analyst Antony Green says the result for the Liberals tonight is a "disaster", and Federal Liberal MP Andrew Hastie agrees, but says there are opportunities for the federal Liberal party ahead of the next election.

"It is a disaster. But there are some green shoots and if you look at the outer metropolitan area where there is a cost crisis, mortgage stress, housing shortage, where we are not getting essential services," Mr Hastie said.

"You are seeing massive swings. You saw it in Kalamunda and if you go south of the river and you look at Rockingham, Secret Harbour, Darling Range and then into my neck of the woods with Dawesville, Madura, Murray Wellington. 

"These seats are swinging hard against the government and so I think federally what that means is there are opportunities for us if we can demonstrate we are better at managing the economy and delivering cost-of-living relief for working families and seniors."

Libby Mettam said she called Roger Cook to congratulate him on his election win.

"The people of WA have cast their vote and the result is certainly very clear," she said.

“Is this the result I hope for? Of course not. Is this what we have been working for? Absolutely not and what we will take from tonight's lessons on how we can do better."

Ms Mettam said it would be a night of reflection for the party.

"It is fair to say it is not the result that we hoped for but we will continue to work for the people of WA," she said. 

"We will continue to advocate on behalf of the people of WA and we will continue to hold the Cook Labor government to account."

“But for tonight, it is a night of reflection and we will continue to keep working for the people of WA going forward. 

"Can I thank each and every one of the people of WA who voted for us and for those that didn't, we are listening."

There’s been a pronounced swing against the government in regional Western Australia.

Geraldton’s Labor MLA Lara Dalton was brought to tears and embraced by family and supporters when the current figures from Geraldton appeared on the ABC’s election night broadcast.

With 16 per cent of the vote counted, there’s been a 26 per cent swing against Ms Dalton, with most of that support being picked up by Independent candidate (and former Geraldton Mayor) Shane Van Styn.

The Nationals’ Kirrilee Warr currently leads the first preference count, but ABC election analyst Antony Green says its too early to say who will win.

Perth’s Lord Mayor Basil Zempilas has been elected as the Liberal member for Churchlands in Western Australia’s parliament.

The seat has been more competitive than many observers anticipated, given it was the government’s most marginal electorate going into this election.

But now that pre-poll votes have been counted, the ABC’s Chief Elections Analyst Antony Green says it’s clear Mr Zempilas has defeated the first-term Labor MP Christine Tonkin in the western suburbs seat.

Last year some Liberal members had agitated to install him as leader, despite the fact he wasn’t a member of parliament, but that failed when put to the party room.

We've now received a preference count in Nedlands, and like the seat of Churchlands, Labor is getting about three quarters of the preferences there.

The Greens have done relatively well there, as well as an independent.

That's helping Labor stay competitive in that seat as well.

On many levels, this has been quite a remarkable election.
