"Another loss" - Super Computer predicts results for Round Four of The Rugby Championship

The Rugby Championship heads into Round Four this weekend with the competition already beginning to split in two.

New Zealand and Australia have seized the early initiative, sitting first and second on the table, while Argentina and South Africa are struggling to keep pace.

After another weekend of tight margins and bruising contests, the question is whether the underdogs can finally flip the script — or if it’s simply a case of

another loss in waiting.

The supercomputer at Sports4Cast has run the numbers, and the predictions don’t make pleasant reading for the trailing nations.

INFOTEAM FORECASTS & PREDICTED SCORES

Date	Time (Local)	Match	Prediction	Predicted Score
Sat, 13 Sep	04:00	Australia vs Argentina (Sydney)	Australia 62% — Argentina 35%	Australia 30 – 25 Argentina
Sat, 13 Sep	07:05	New Zealand vs South Africa (Wellington)	New Zealand 69% — South Africa 28%	New Zealand 21 – 19 South Africa

Context: How We Got Here

The Rugby Championship has already delivered drama across the opening three rounds:

Australia sit on 9 points after two wins, including a nail-biting 28-24 victory over Argentina last weekend.
New Zealand top the table with 10 points, unbeaten at home and grinding out a 24-17 triumph against South Africa in Round Three.
Argentina and South Africa both trail on 5 points, having managed just one win apiece so far.

That sets the stage for two clashes where the supercomputer predicts… well, more of the same.

Match One: Australia vs Argentina

In Sydney, the Wallabies are tipped to edge Los Pumas 30–25. The model leans 62% towards Australia, reflecting both home advantage and recent form. Argentina have shown flashes — their fightback in Round Three kept Australia under pressure to the final whistle — but the margins suggest this is another test they’ll come up just short in.

Match Two: New Zealand vs South Africa

Wellington hosts the round’s blockbuster. The All Blacks are forecast to squeeze past the Springboks 21–19, despite a narrow prediction margin. With a 69% probability of victory, New Zealand’s blend of set-piece solidity and game management gives them the edge. But South Africa, stung by last week’s seven-point defeat in Auckland, will feel they left opportunities behind — making this one a potential thriller.

Mike and Zara Tindall are among rugby union’s five richest couples

From high-profile partnerships to humble beginnings, these power pairs have amassed impressive fortunes while leaving a lasting legacy. With stories of childhood love, philanthropic missions, and royal connections, each couple brings their own unique flair to the game.

Here’s a look at the top rugby couples whose bonds—and bank accounts—have made them iconic.

Johnny & Laura Sexton – The Dublin Dream Team (£6m)

From teenage sweethearts to one of rugby’s wealthiest pairs, Johnny and Laura Sexton have captured fans’ hearts as much as Johnny’s kicks have clinched games. Their love story began at Rathgar Tennis Club, blossoming all the way to marriage in 2013.

With three kids cheering on dad from the sidelines, the Sextons are as iconic off the field as Johnny is on it. The couple’s journey—from Saint Mary’s College to University College Dublin—stands as a testament to commitment and love.

Siya & Rachel Kolisi – The Power Couple with a Purpose (£10m)

Siya and Rachel Kolisi’s £10 million empire wasn’t just built on rugby; it’s infused with purpose. The Kolisis are widely admired for their philanthropic work, especially through the Kolisi Foundation, which uplifts underprivileged communities.

Although the couple recently parted ways, Rachel remains a key influence in Siya’s life. Now back with the Sharks after a stint in France, Siya continues to value her steadfast support. Despite the split, their legacy as South Africa’s “golden couple” lives on.

Mike & Zara Tindall – Royal Connections and Reality TV (£20m)

“Fridge” by nickname, royalty by association, Mike Tindall’s wealth and fame go beyond rugby. Married to Zara Phillips, Queen Elizabeth II’s granddaughter, Tindall has firmly planted himself in British pop culture. From breaking his nose eight times to breaking records in rugby, Mike’s career has been nothing short of resilient.

Since retirement, he’s taken his profile to new heights with appearances on shows like I’m a Celebrity… Get Me Out of Here and Bear Grylls: Mission Survive. His estimated £20 million fortune proves rugby and royalty make quite the combo.

Jonny & Shelley Wilkinson – A Hero’s Quiet Empire (£22m)

Jonny Wilkinson isn’t just a legend on the field; he’s a legend in love too. After leading England to the 2003 Rugby World Cup victory, Wilkinson has kept a low profile with his wife, Shelley Jenkins.

They wed in 2013 on the scenic French Riviera, and now with a young son, they’re embracing family life in the quiet lane. Worth £22 million, Jonny’s legacy as one of rugby’s finest is matched by his financial success and family’s privacy.

Sonny Bill & Alana Williams – The Ring, the Romance, and the Riches (£20m)

Sonny Bill Williams, the Kiwi powerhouse, is famed not just for rugby but for his ventures into the boxing ring. Known for his versatility on the field and knockout power off it, he’s carved a unique sports career.

His whirlwind romance with Alana Raffie, culminating in a four-week engagement, sparked as much intrigue as his sporting accomplishments. Now worth £20 million, the couple’s success story includes rugby, league, boxing, and plenty of endorsements.
