Robbie Deans was left a relieved coach after watching his Wallabies come back from 13 points down to beat Argentina 23-19 on Saturday.
After back-to-back losses to the All Blacks, the Wallabies have now fought back to win their last two, having beaten South Africa last weekend.
"I wouldn't underestimate what we did here tonight, I mean the Argentines are a good side, no team has played consistently against them," Deans said.
"They're a great side, a side that plays with a lot of pride and a lot of ambition."
Australia full-back Berrick Barnes, who kicked 13 points for his side, praised his team-mates character after being part of the comeback.
"They made it hard for us in every facet of the game," he said.
"They scrapped a couple of tries off silly turnovers and made it really hard for us.
"But tonight we were able to fight back from 19-6 down. The bench came on and gave us great impact and straight-line running, which helped us."
