"Lynagh vs Carreras" - 3 Key Battles: Australia vs Argentina - Rugby Championship Round 3

Both the Wallabies and Los Pumas have one win to their respective Rugby Championship campaigns, with major upset victories witnessed throughout the tournament's opening fortnight. Australia bagged one of the all-time great Rugby Championship shocks, as Joe Schmidt's men turned round a 22-0 deficit to then hand the Springboks a 38-22 defeat.

Argentina executed an equally impressive triumph over the All Blacks in round two, as the men in blue and white secured their first ever victory over New Zealand upon home soil. The tournament was blown wide open by the 29-23 Argentine win, with Los Pumas well in the hunt for their first ever Rugby Championship title, since they expanded the old Tri Nations back in 2011. So, ahead of this must-win match for both the Wallabies and Pumas, here is a look at three key battles that could well decide the outcome in Townsville.

It’s the clash of the playmakers in Brisbane, as 22-year-old Tom Lynagh returns to the Wallabies No.10 shirt against the Pumas' versatile game-changer Santiago Carreras.

Tom Lynagh, son of the Wallabies legend Michael Lynagh, makes his comeback to the gold jersey after suffering a concussion in the Lions series, in a hotly scrutinized breakdown clear-out that saw Ireland’s Dan Sheehan handed a ban. Having missed the two-test tussle with South Africa, Lynagh now reclaims the fly-half role alongside veteran scrum-half Nic White, who continues his farewell tour. It’s a fascinating blend of youthful promise and old-school nous for the Wallabies halfback axis.

Despite just six caps to his name, Lynagh’s composure and natural game management have drawn comparisons to his famous father. He’s already impressed in Super Rugby with the Reds and will be eager to stamp his authority against Argentina after the heartbreak of a Lions series defeat in the Summer.

Standing opposite him is Carreras, the Bath-bound playmaker who has become a cornerstone of Los Pumas’ attack. Originally a fullback and wing, Carreras has grown into a confident conductor at fly-half, steering Argentina to famous victories – none more memorable than their shock win over the All Blacks in Buenos Aires a fortnight ago. With Tomas Albornoz sidelined, Carreras once again takes the reins, bringing creativity, versatility, and a fearless running game.

Two powerhouse back rows collide in Brisbane, with Wallabies skipper Harry Wilson back from a knee injury to lock horns with the battle-hardened Pablo Matera. Wilson has quickly grown from promising youngster into the heartbeat of Joe Schmidt’s Wallabies. The Queensland Reds talisman was left out of Eddie Jones’ 2023 World Cup squad, but his resurgence has been nothing short of emphatic.

Appointed Wallabies captain in 2024 once Joe Schmidt took over the helm, Wilson led Australia to a narrow win over Argentina in La Plata before stamping his authority on the Lions series in 2025. His barnstorming brace against South Africa in Round One of the Rugby Championship helped Australia turn the 22–0 deficit into a famous comeback and showed why he’s now indispensable to the men in gold. Tireless, direct and full of energy, Wilson embodies the new era of Wallabies spirit.

Standing opposite him is a man who has been the soul of Los Pumas for more than a decade. Pablo Matera, Argentina’s most-capped player of all time with 114 appearances and counting, remains a relentless force at 32-years-old. The former Jaguares, Crusaders and Stade Français enforcer is famed for his uncompromising breakdown work and emotional leadership, and Matera will forever be remembered as the captain who inspired Argentina’s first-ever win over the All Blacks in 2020. Even now, he remains a talismanic figure, blending wild-man ferocity with his commanding experience.

This duel is as much about leadership as it is physicality. Wilson, the newly minted Wallabies skipper, carries the weight of expectation from a rugby nation on the resurgence. Matera, the battle-scarred Puma, thrives on defying the odds, with no shortage of personal animosity expected when they collide.

The clash in the midfield between Joseph Sua’ali’i and Santiago Chocobares is set to be one of the most explosive contests of the Rugby Championship's third round. Sua’ali’i, the 22-year-old sensation who switched from rugby league to union, has already lived up to his blockbuster billing.

The Waratahs star was fast-tracked into the Wallabies setup before even playing Super Rugby and has since lit up the international stage with his size (6ft 5in), athleticism and highlight-reel moments. His power in contact, league-style offloads, and ability in the air make him one of Australia’s biggest attacking threats, and the face of the future of the green and gold jersey.

Across from him is Santiago Chocobares, a battle-hardened 26-year-old who tasted history upon his Pumas debut, through Argentina’s first-ever win over the All Blacks back in 2020. Now a regular for Toulouse in France’s Top 14 and with an ever growing cabinet of French league and Champions Cup winners medals, Chocobares knows what it takes to win under the bright lights of the biggest stages.

Chocobares brings crunching defense, smart distribution, and relentless physicality to the blue and white midfield, with his tenacity shown to recover from a potentially season-ending knee injury, he suffered against South Africa in the 2024 Rugby Championship. Gritty determination through his recovery and a sprinkle of luck kept Chocobares from requiring surgery, as he returned to Toulouse duties less than two months later.

If Sua’ali’i can find space and impose his physical gifts, the Wallabies will have a weapon few teams can handle. But if Chocobares dominates the collisions and denies him front-foot ball, Argentina will feel confident of controlling the tempo.
