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 up and 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.
