"Beauden Barrett vs James O'Connor" - 3 Key Battles - All Blacks vs Wallabies in Rugby Championship

Whilst the All Blacks have held possession of the Bledisloe Cup since 2002, Australia come into this match riding a wave of momentum at the top of the Rugby Championship table. The closest iteration of the RC in recent memory sees all four nations level on two wins and two losses, with the Wallabies pulling in front on points difference and accrued bonus points.

Once again, we've surveyed the squads for this Southern Hemisphere showdown, and picked out the three key battles that could well decide the outcome in Auckland. With little over 24 hours between now and the start of round five, here's the most decisive clashes that could turn the tide at Eden Park.

Both the All Blacks and Wallabies have rolled the dice out wide for this Round 5 showdown, and the new-look wing duels could prove decisive. For New Zealand, Caleb Clarke makes his long-awaited return, pulling on the black jersey for the first time this year after a seven-week layoff from the national squad as he dealt with an ankle injury.

Clarke has been easing back through the NPC with Auckland, crossing the whitewash against Wellington, Tasman and Counties Manukau, and looks hungry to reassert himself on the Test stage. The explosive 25-year-old is no stranger to headline moments, having burst onto the scene in 2020 with barnstorming runs that have made him one of the most feared young wingers in the world.

Partnering him is Leroy Carter, the All Blacks’ latest debutant who marked his maiden cap against the Springboks with a sharp try in Wellington, before South Africa took full control in the Kiwi capital. A sevens star with over 100 caps on the circuit, Carter brings pace, footwork and a natural eye for space – an asset the All Blacks will be desperate to unleash against Australia.

Across the line, Harry Potter returns on the right wing for the Wallabies, a player as versatile as he is a relentless workhorse. Potter is well known to UK rugby fans, thanks to his apprenticeship in England with Leicester Tigers, where he became a Premiership champion, and has quickly shown he belongs in gold.

Potter's ability under the high ball and strong finishing make him a dangerous weapon. Alongside him is Corey Toole, the speedster billed as the fastest man in Super Rugby. A former sevens standout and Olympian, Toole’s acceleration and broken-field running can turn a half-chance into seven points in a heartbeat. With Clarke’s power, Carter’s dynamism, Potter’s magic (we couldn't resist) and Toole’s raw pace, this is a battle where one flash of brilliance could swing the match.

Two veterans of the game square off in Auckland, with Beauden Barrett and James O’Connor bringing a combined 200+ Test caps worth of experience to the No. 10 jerseys. For the All Blacks, Barrett links up with returning scrum-half Cam Roigard, a fresh partnership that will demand his adaptability.

The 33-year-old playmaker has spent the Rugby Championship steering New Zealand’s attack with his trademark speed, laser-like boot and composure under pressure. A two-time World Rugby Player of the Year, Barrett sits third on the All Blacks’ all-time points list and remains capable of winning matches with a flash of brilliance. With 14 points already from the tee in this year’s tournament, and sharing kicking duties with Jordie Barrett and Damian McKenzie, his influence will again be central.

Across the field, James O’Connor reclaims the Wallabies’ No.10 jersey after Tom Lynagh’s brief run at fly-half. At 35, O’Connor’s return is a story of redemption in Australian gold. Once the Wallabies' chosen one – and the youngest Super Rugby debutant in history – his career unraveled amid off-field issues before he rebuilt himself in Europe and earned a second shot with the Wallabies.

Now a steadying presence, O’Connor has racked up 23 points in this year’s Championship and brings tactical nous, a reliable boot, and proven leadership that Joe Schmidt’s side badly needs. Barrett thrives on tempo and flair, O’Connor on guile and control. The clash of styles at fly-half could go a long way in deciding whether the Bledisloe stays black or turns gold.

The set-piece battle at Eden Park will be fierce, and nowhere more so than at scrum time where Tyrel Lomax and James Slipper collide. For Lomax, the tighthead jersey is becoming increasingly secure after a strong return to the starting side.

The Australian-born prop, son of Kiwi league international John Lomax, actually came through the Wallabies system first, earning 10 caps for the Australia U20s in 2015 and 2016. A powerful scrummager with a hard edge, he switched allegiance after moving to New Zealand, progressing through Tasman, the Highlanders and Hurricanes before becoming a regular All Black.

Lomax started the 2023 Rugby World Cup Final and was crowned Māori Player of the Year in 2024. Dropped earlier this Championship after some patchy form, he has responded by forcing his way past Fletcher Newell and now carries the responsibility of anchoring the All Blacks’ front row.

Opposite him, James Slipper writes a new chapter in Test rugby history. The Wallabies stalwart becomes the first Australian to reach 150 caps, a milestone that places him alongside Alun Wyn Jones and Sam Whitelock in the sport’s most exclusive company.

Debuting in 2010, the 36-year-old is already the most-capped prop in world rugby, his longevity a testament to consistency and resilience. Slipper’s set-piece nous and streetwise experience will be vital if the Wallabies are to blunt New Zealand’s scrum and give James O’Connor a clean platform to play from.

Lomax brings power and raw aggression, Slipper brings savvy and history-making durability. In a match sure to hinge on small margins, this front-row duel could tilt the balance between dominance and damage limitation.
