Australia’s Wallabies are no longer simply searching for a best starting XV.
Head coach Les Kiss has set a much bigger target: build enough depth to field two Test-quality teams before Australia hosts the 2027 Rugby World Cup.
That ambition is shaping the Wallabies’ preparations for their two-Test series against Argentina, with Kiss making significant changes to the forward pack while keeping the backline that helped Australia crush Japan 56-17 earlier this month.
The message from the new coach is clear: selection is still wide open.
“Now, I need to know that I’ve got two good 15s. That’s what I need to get to,” Kiss said.
Rather than immediately settling on a preferred starting lineup, Kiss is using every Test to examine his options, build combinations and create genuine competition for places.
A radically different Wallabies forward pack
For Australia’s opening Argentina Test in San Salvador de Jujuy, Kiss has rotated heavily among the forwards.
Regular captain Harry Wilson is being rested, with experienced prop Allan Alaalatoa taking over as captain. Rob Valetini moves into the No. 8 position, while several other forwards return to the starting side.
Isaac Kailea is also back in the Test lineup for the first time since 2024.
The backline, meanwhile, has been kept largely intact following Australia’s emphatic 56-17 victory over Japan.
That continuity gives Kiss an opportunity to assess whether the emerging combinations can reproduce their attacking form against a significantly tougher opponent.
Suaalii’s return adds another selection headache
One of the most intriguing developments is the return of Joseph-Aukuso Suaalii.
The highly regarded centre has recovered from a hamstring issue but will begin the Argentina match on the bench rather than immediately reclaiming the No. 13 jersey.
That is significant because Isaac Henry and Hunter Paisami impressed in the midfield during Suaalii’s absence.
Kiss has nevertheless indicated that he continues to see Suaalii primarily as an outside centre, even while acknowledging his ability to move into other positions if required.
The competition is exactly what the coach wants.
Instead of relying on reputation alone, players now have to demonstrate that they deserve their place.
Injuries are testing Australia’s depth
The Wallabies’ depth strategy is also being accelerated by injuries.
Winger Dylan Pietsch and centre Len Ikitau are among the players unavailable for the Argentina opener, creating opportunities for other members of the squad.
That has helped players such as Henry and Paisami make their case.
Reuters reported that Kiss is deliberately using the current Test window to strengthen the squad rather than narrowing his options too quickly. The Guardian similarly noted that the extensive forward reshuffle is part of Australia’s effort to test its depth ahead of the 2027 World Cup.
From rebuilding to genuine competition
The timing matters.
Australia is less than 14 months away from hosting the 2027 Rugby World Cup, and every Test is becoming part of the preparation process.
The Wallabies have already shown signs of improvement under Kiss, winning their two most recent matches against Japan after earlier defeats to Ireland and France.
Australia won 35-32 in Japan before producing a much more convincing 56-17 victory in Townsville.
The Argentina series therefore represents a considerably more demanding examination.
Australia will play Argentina in San Salvador de Jujuy on August 30 before travelling to Mendoza for the second Test on September 6. Rugby Australia lists a September 27 home Test against South Africa in Perth as the Wallabies’ next major challenge after the Argentina series.
The World Cup clock is already ticking
Kiss took over from Joe Schmidt with Australia’s home World Cup firmly in the background.
The objective isn’t simply to find 15 players who can win matches.
It is to build a squad capable of surviving injuries, suspensions, fatigue and the pressure of a World Cup campaign.
That means Australia needs quality beyond its first-choice players.
Rugby Australia’s 2026 selection process has already featured uncapped players and new combinations, reflecting the broader push to expand the Wallabies’ options. Earlier in the year, the national squad included several uncapped players as Australia searched for additional depth across the roster.
And Kiss appears determined not to close those doors prematurely.
Argentina could reveal just how deep the Wallabies really are
The Argentina Tests offer an ideal measuring stick.
The Pumas are physically demanding, tactically unpredictable and capable of punishing teams that lose control of territory or possession.
For Australia, the challenge goes beyond winning.
Kiss needs to discover which players can perform under pressure, which combinations can survive against elite opposition and whether his second-choice options can genuinely operate at Test level.
That could prove more important than the result itself.
The Wallabies already have a clearer first-choice picture in some areas. But the coach’s comments suggest he wants something bigger: two teams strong enough to push each other every week.
If he succeeds, Australia could enter the 2027 World Cup with something it has often lacked—serious depth across the squad.
And that competition for places could become one of the Wallabies’ biggest weapons when the tournament finally arrives.
The question now is whether the players outside the current starting XV can force Kiss into making some very difficult decisions.
