SA Election 2026 As It Happened: Labor wins state election in a landslide; Big swings to One Nation, Libs hit rock bottom

And that's a wrap for the 2026 South Australian election. The Labor Party has retained power in South Australia as Peter Malinauskas secures a second term. But One Nation's surge will leave the Liberals, and all of Canberra in a cold sweat. Thanks for staying with us.

Roars of a brimming crowd at Labor HQ chanted 'four more years' as Peter Malinauskas made his way to the podium followed by his wife and four children.

"More than anything else tonight I'm overwhelmed with a sense of gratitude," Malinauskas said.

"A gratitude to so many people who have provided this government with the opportunity to continue to serve."

The premier thanked Liberal Leader Ashton Hurn and One Nation Leader Cory Bernardi for their concession calls earlier in the evening.

"My government stands ready to work with each and everyone of you as long as it is in the interest of South Australia," Malinauskas said.

He also thanked Labor candidates, volunteers and "the mighty trade union movement".

Pauline Hanson has claimed success following the South Australia election, after an overwhelming surge in the party's vote across the state.

Overwhelming chants of "Pauline" filled One Nation HQ as the party's leader addressed a sea of orange.

"The last time I saw a crowd like this was when we won 11 seats in Queensland in 1998," Hanson said.

"It's the start of a new beginning for the people South Australia, for the people of Australia."

Hanson congratulated Peter Malinauskas on his victory, but warned she's leaving "some landmines" behind in South Australia as she heads back to Canberra.

"I'm leaving you some landmines; they're called One Nation members of parliament," Hanson said.

"So I suggest you don't step on them because they will explode."

After a strong performance in the South Australia election, Cory Bernardi and Pauline Hanson address One Nation supporters.

Watch it live here.

Liberal leader Ashton Hurn is expected to address the party faithful when she arrives at Liberal headquarters in the next 10 minutes or so.

The Liberal primary vote hasn't dipped into the 20s in the last 50 years but tonight, it's sitting at 18.2 per cent.

So far, the party's projected to claim just three seats. But it's poised to reclaim opposition status because One Nation only holds two seats.

Political editor Charles Croucher says One Nation's powerful performance in the South Australian election will send "seismic shockwaves" through Victoria - the next state to head to the polls.

"It would be a lightning bolt to Victoria, particularly for Labor who have relied on some of those regional seats and outer suburban seats," Croucher said.

"The overriding emotion for One Nation voters is anger, they have been left behind.

"That is so much more prevalent in Victoria than it is in South Australia."

Croucher said he "would not be shocked" if Victorian Premier Jacinta Allan is bumped from the top job within the next week.

One Nation continues to lead in the race for runner-up tonight.

A wave of orange support has mustered up an 18.3 per cent swing in One Nation's favour.

The Liberals are trailing by about 2.2 per cent, after suffering a 17.1 swing away from the LNP.

Both parties have claimed one seat tonight, according to 9News projections.

Former Liberal leader Vincent Tarzia has lost half of his vote in the seat of Hartley in north-east Adelaide.

Labor candidate Jenn Roberts is leading the race for Hartley so far with nearly 40 per cent of the primary vote, while One Nation has also picked up a 15.4 per cent swing.

"One in every two people who voted for Vincent Tarzia at the last election has voted for someone else," political editor Charles Croucher commented.

Tarzia admitted it had "been a tough start" to the election count.

"There's lots of pre-polls and postal votes to come," Tarzia told 9News.

"We respect the decision of the electorate and we've gotta learn and adapt and get better from that."

Tarzia said he believes his result would have been "far worse" had he not handed the Liberal leadership to Ashton Hurn 100 days ago.

"I've thrown everything at this and I'm very grateful for the career I've had thus far."
