UFC 331 is the UFC's first trip to Los Angeles in eight years, and it's headlined by a flyweight title rematch that lasted 26 seconds the first time.

Joshua Van defends against Alexandre Pantoja at Crypto.com Arena on Saturday 19 September in the US, which is a Sunday late-morning card in Australia.

The main card starts at 11:00am AEST, and as with every numbered UFC event here, the three segments sit on three different services. That's the bit that trips people up.

How to Watch UFC 331 in Australia

Australia splits a numbered UFC card three ways. Knowing which platform holds which part saves you paying for the wrong one.

Main card (Van v Pantoja, Tsarukyan v Ruffy and the rest of the top of the bill).

Pay-per-view through Main Event, available on Foxtel and Kayo Sports. You don't need an ongoing Kayo subscription to order the PPV.

Prelims. Paramount+ and Network 10. Not part of the PPV, and Ten means they're free to air.

Early prelims. Paramount+ and UFC Fight Pass.

The UFC's US deal moved everything onto Paramount+ over there with no pay-per-view, so American guides to watching UFC 331 don't apply in Australia. A Paramount+ subscription here gets you the prelims and early prelims, and nothing from the main card.

UFC 331 Start Times Across Australia

Australia is still on standard time in September, so no daylight saving to worry about for this one.

Main card:

AEST (NSW, VIC, QLD, ACT, TAS): 11:00am Sunday 20 September

ACST (SA, NT): 10:30am Sunday 20 September

AWST (WA): 9:00am Sunday 20 September

Prelims start two hours earlier (9:00am AEST, 8:30am ACST, 7:00am AWST) and early prelims at 7:30am AEST (7:00am ACST, 5:30am AWST).

Main event walkouts usually land 90 minutes to two hours into a main card, so Van and Pantoja should be in the octagon around 12:30pm to 1:00pm on the east coast.

Five-round co-main and the flyweights being quick starters means it could run either side of that.

UFC 331 Fight Card

Main card:

Joshua Van v Alexandre Pantoja, flyweight title

Arman Tsarukyan v Maurício Ruffy, lightweight (five rounds)

Patrício Pitbull v Doo Ho Choi, featherweight

Alonzo Menifield v Iwo Baraniewski, light heavyweight

Prelims:

Gable Steveson v Sean Sharaf, heavyweight

Marlon Vera v Charles Jourdain, bantamweight

Tai Tuivasa v Robelis Despaigne, heavyweight

Edmen Shahbazyan v Brunno Ferreira, middleweight

Early prelims:

Giga Chikadze v Joanderson Brito, featherweight

Casey O'Neill v Eduarda Moura, women's flyweight

Ryan Gandra v Ozzy Diaz, middleweight

Michael Aswell Jr v Joo Sang Yoo, featherweight

The card has already changed shape twice. Tsarukyan was booked to fight Charles Oliveira before Oliveira withdrew, and Ruffy stepped in.

A Kayla Harrison v Amanda Nunes bantamweight title fight was postponed from UFC 324 earlier this year and is yet to be rebooked.

Two Australians are on the card. Tai Tuivasa meets Robelis Despaigne on the prelims, and Casey O'Neill opens against Eduarda Moura on the early prelims.

What's at Stake at UFC 331

Van and Pantoja fought at UFC 323 in December 2025 and it was over in 26 seconds. Pantoja's arm gave way and the fight was stopped, making him the only fighter in UFC history to lose a title to an injury stoppage.

Van, at 24, became the second-youngest first-time champion in UFC history behind Jon Jones, and the first champion born in the 2000s. Nobody, including Van, treats that as a settled result.

Pantoja holds the record for most wins in UFC flyweight history with 14, and five title-fight wins, second only to Demetrious Johnson in the division.

Van brings a seven-fight winning streak and lands 8.43 significant strikes a minute, the second-highest rate the UFC has ever recorded.

Volume against experience, with a five-round main event to sort it out. With title belts and champion standings across the divisions in play here, it's worth casting an eye over the UFC and MMA futures odds too.

Tsarukyan has won five straight at lightweight and is 10-1 across his past 11 in the UFC, with Ruffy, the Brazilian striker, stepping in for Charles Oliveira and taking a big step up.

For Australian viewers the Tuivasa fight carries a grim milestone. Bam Bam is on a seven-fight losing streak, tied with BJ Penn for the second-longest in UFC history. One more and he matches Tony Ferguson's record of eight.

UFC 331 Betting Markets

For the latest UFC 331 odds and markets, check out our dedicated UFC odds page here at Sportsbet.

Beyond the head-to-head on each bout, the markets that draw the most attention on a card like this are the method of victory, round betting and whether the fight goes the distance.

The main event is a five-rounder between two fighters who tend to push a high pace, so the distance and rounds markets are where the debate sits.

Van's output is enormous, but Pantoja has gone five rounds in title fights before and Van's first title fight ended before either man had thrown much.

The heavyweight bouts are the opposite case. Tuivasa and Despaigne have finishing power and little interest in the scorecards, which is why the inside-the-distance and early-round markets get most of the traffic on fights like that.

If you want a steer on how the method and rounds markets on these bouts might land, our UFC Fight Night tips break down where the value tends to sit.
