Captain Rocky Elsom admitted Australia were driven by a desire to "make amends" as they crushed Wales 33-12 at the Millennium Stadium.
The Wallabies had been beaten 9-8 by Scotland last week but bounced back with tries from Digby Ioane, James Horwill, David Pocock and Tatafu Polota-Nau and 13 points from fly-half Matt Giteau - last week's villain with a late missed conversion.
"It's hard to say exactly what improves the team but we just really wanted to make amends and we didn't want to waste this opportunity," Elsom said, speaking to BBC2.
"We wanted to make amends for the way we played last week - we had more in us than that but that's all we put on the park.
"It would have been a surprise if we hadn't come out hard today, I would have been very surprised by that."
Elsom is encouraged for the future of his young side, and added: "We'd like to think there's a lot more in us.
"We've learnt a few lessons on this tour and the key is to carry them forward so that we develop into a better side than we are now."
Australia coach Robbie Deans was pleased by his side's progress but felt they had been close to producing a similar performance in previous weeks.
The Wallabies beat England 18-9 and were held 20-20 by Ireland, but Deans said:
"They haven't been far away, sometimes you just need that element of luck or good management.
"You could see the belief kick in tonight, it was a good effort - particularly the way they denied Wales and they kept going until the end, it was a good step for us."
He admitted the Murrayfield setback was a motivating factor, but said: "You never need that, but obviously there was a source of frustration.
"We didn't play well (against Scotland), but tonight we were a little bit more direct and we got what we deserved."
Meanwhile, opposite number Warren Gatland admitted defeat following their Millennium Stadium lesson.
"I think they dominated us in most facets of the game," he said.
"I was disappointed, we seemed to be quite flat. Once they were in control they were quite happy to play territory and they dominated the air quite well."
