The Wallabies will call on reinforcements as they attempt to right recent history in Argentina and sweep their two-Test tour, with coach Les Kiss set to benefit from his smart squad management.
Kiss left skipper Harry Wilson and fellow forwards Lukhan Salakaia-Loto, Fraser McReight, Josh Nasser and Taniela Tupou on ice for the weekend's gritty 27-21 win over the Pumas, while star centre Len Ikitau was also given another week off to complete his recovery from injury.
But after an energy-sapping 80 minutes in San Salvador Jujuy, where the Wallabies noticeably drifted in the final quarter, Kiss will be able to thrust the fresh legs into his 23 this week, while prop Angus Bell and Joseph-Aukuso Suaalii should have plenty left in the tank after 40 and 15 minutes off the bench respectively.
"We'll look at the game, I think some guys; Isaac [Kailea] had his first game for a while in the gold jersey and did a great job in that first half for us, Belly came off the bench, so maybe there could be changes in that area," Kiss told reporters post-match.
"We needed to see a little bit of the two locks together [Josh Canham and Jeremy Williams], and Lachlan [Shaw] also did a good job; we've also got Lukhan there and we'll find some game time for him as well. Back-row again, you'd probably see Harry pop his head in.
"So look, the changes aren't done willy-nilly, we're trying to make sure we grow deeper and just keep ourselves healthy because after this weekend and into next weekend there's still some big games including next week, and we want to make sure we can find the varying ways that we can use our squad.
"Those options will narrow down as we get closer towards the end of the year, but at this stage I'm really happy with how the forward pack have bought into them."
While there are plenty of new faces in the Wallabies squad this year, there are enough old heads who will recall the twin hammerings in the second Pumas Tests of 2022 and 2024.
Even last year Australia arrived in Sydney on the back of a dramatic post-siren victory over Argentina in Townsville, only to turn in an ill-disciplined and error-riddled performance in front of a sell-out crowd at Allianz Stadium. It proved to be a telling defeat as Australia won just one of their next seven Tests to round out 2025.
And the Wallabies can't hope to rely on more Pumas errors this weekend, after Argentina turned over the ball 18 times in Jujuy, with star backs Santiago Carreras and Rodrigo Isgro among those to make rudimentary handling mistakes just when the hosts were building momentum inside the attacking half.
But Australia's defensive work also deserves some credit, after keeping an opposition team to under 25 points for the third time in four games. New defence coach Scott McLeod will want that number to drop to around 20, however, particularly with far greater threats coming on the horizon in the shape of the Springboks and All Blacks.
Still, the double-team hit Bell and replacement hooker Billy Pollard delivered on winger Ignacio Mendy, which allowed Fraser McReight to swoop in and win a vital turnover, should serve as a marker for McLeod as he looks to further embed his defensive blueprint.
"Really buying into what it takes when we haven't got the ball to dig in and find a way to make sure we can repel the opposition," Kiss said.
"We weren't perfect for sure, but we really fight hard for each other and fight hard for staying in the game under the best terms that we can. They (Argentina) are a dangerous side.
"Talking to Al (Allan Alaalatoa) and Fraser afterwards, who took over captaincy after Al left, there was a certain strong calmness on the pitch. We didn't let the pressure get on top of us and weigh us down.
"Fraser talked about how the team didn't panic at all. They stayed calm and connected to the things that we believe can contribute to staying together and connected."
