Australia have won three matches in a row for the first time since 2017 after beating Argentina 27-8 on Saturday in a Rugby Championship match as James O'Connor made a successful test return from injury.
Samu Kerevi's powerful running set the scene for the Wallabies as the centre set upand scored a try to create a 17-3 lead for the Wallabies at halftime.
Australia lost their rhythm before O'Connor came off the bench after 56 minutes — his first game since May because of neck and groin injuries.
Replacing Quade Cooper at flyhalf, O'Connor kicked a penalty then set up a try for winger Andrew Kellaway to seal the result.
The victory followed back-to-back Rugby Championship wins by Australia over South Africa. The Australians play Argentina again next Saturday before leaving on an overseas tour of Japan and the United Kingdom in October and November.
"It wasn't with the polish we wanted and I thought we left a lot of opportunities on the park, especially in the second half," Australia coach Dave Rennie said. "We went really hard first half. I thought that should have paved the way to run them off their feet but they are tenacious, they hang in there and scramble really well."
Kerevi's line-busting form alongside Len Ikitau was a highlight, as was Kellaway's form on the wing and Reece Hodge's effort at fullback.
Hodge deked and strongly skipped through two attempted tacklers for the game's first try, kicking and running strongly in general play as he made his case for the No 15 jersey after replacing Tom Banks, who broke his right arm last week against South Africa.
The 23,184-strong crowd, which had earlier watched the All Blacks beat South Africa 19-17 to clinch the tournament title, saw another strong performance from prop Taniela Tupou.
Skipper Julian Montoya scored for Argentina off the back of a maul to open the second half but a yellow card to Marcos Kremer for tripping Hodge hurt their hopes just before O'Connor came off the bench.
