Australia v Argentina Rugby Championship betting tips & odds

Argentina will be desperate to bounce back when they face the Wallabies in Round 4 of the 2025 Rugby Championship at Sydney’s Allianz Stadium on Saturday, September 13.

Last week in Townsville, Los Pumas led for nearly the entire game before conceding a heartbreaking 85th-minute try that gave Australia a 28-24 victory. Now, with the Puma Trophy on the line and both teams still mathematically in the hunt for the title, the return fixture sets up as a must-win showdown.

Top rugby betting sites have Australia at -200, while Argentina sit at +150 despite their strong track record in Sydney — drawing 16-16 in 2020 and claiming a 34-31 win in 2022.

Wallabies coach Joe Schmidt has made four changes to the starting lineup. Fly-half Tane Edmed earns just his second Test start, while Hunter Paisami returns to partner Joseph Sua’ali’i in the midfield. James Slipper returns to the front row, and Jeremy Williams replaces Nick Frost at lock.

Argentina boss Felipe Contepomi has brought in Rodrigo Isgro, Joaquin Oviedo, and Guido Petti to tighten things up after their second-half collapse last weekend. Defensive lynchpin Marcos Kremer remains a key figure after recording 31 tackles in the first Test.

Expect a tighter, more tactical affair in Sydney, with both coaches emphasizing discipline, territory control, and impact from the bench.

Wallabies v Pumas betting predictions

Argentina +5.5 handicap

The Pumas have proven they can control long stretches against Australia, and they’ll be fired up after letting last week’s match slip away. With fresh legs in the pack and Kremer leading a solid defense, Argentina look good to cover the line at -117.65 with BetOnline.

Under 54.5 total points

Both teams leaked points in Townsville, but expect more structure and caution in this return clash. Sydney’s conditions and the pressure of the Puma Trophy should result in fewer open-field tries, making the under 54.5 total points a strong play at -111.11 with BetOnline.

Joseph Sua’ali’i anytime tryscorer

The Wallabies center crossed twice last weekend and has been a consistent threat all season. With Argentina likely to bunch up in defense again, Sua’ali’i offers solid value at +140 to score at any time with BetOnline.
