The Wallabies have completed their Rugby Championship with a 25-19 victory over Argentina in Rosario.
New Zealand-born players scored all the Australians' points with Wellington-born winger Digby Ioane notching a try midway through the second half while North Harbour fullback Michael Harris kicked 20 points.
Australia finished the southern hemisphere's elite championship second behind the All Blacks, with South Africa third and the Pumas ending their debut season in the tournament with a draw and five defeats.
The win is likely to keep coach Robbie Deans in his job until at least the end of the year.
