Wallabies coach Robbie Deans praised his players' effort in Saturday's backs-to-the-wall 25-19 win over Argentina in Rosario.
So satisfied was Deans with the result that he hailed it as one of the most satisfying wins of his tenure.
"I'm proud of the group," he told AAP.
"I think tonight was evidence of the meaning to this group and obviously we've experienced a fair amount of adversity but we'll get the benefit of this time.
"One of our focal points was not to let the crowd in, and particularly early.
"They silenced the crowd early (leading 15-6) and they didn't allow (the Pumas) to get a leg-up.
"This is a fantastic experience for these blokes... it was genuine old-school."
Australia, who were without more than half of their first-choice team through injury also had to overcome the early loss of lock Kane Douglas (head knock) but Scott Higginbotham came off the bench and starred along with fellow flanker Michael Hooper.
This win was a morale-boosting one for the Wallabies and almost certainly ensured that Deans would see out the year in his job.
The Wallabies' next match is a third Bledisloe Cup Test against unbeaten New Zealand in Brisbane on 20 October before they head on their three-match end-of-year to Europe.
