The Wallabies did just enough to record a 25-19 victory over the Pumas in a scrappy match in Rosario on Saturday.
The win will come as a boost for Australia who have had to deal with a heavy injury toll this season, whilst Argentina will be frustrated at missing out on the opportunity to record their first victory of the Rugby Championship.
Both teams struggled to build any sort of meaningful momentum in a match dominated by the sound of the referee's whistle as the high error-rate continually snuffed out any continuity.
The visitors took a 15-9 lead into the half-time break with five penalties from the boot of Mike Harris, and it was not until the 65th minute that wing Digby Ioane got over for the first try of the game.
Argentina made a late surge when Juan Imhoff was forced over the tryline, but they ultimately came up short and had to be satisified with a losing bonus point as the Wallabies held on.
