The defending Rugby Championship winners and long-time Bledisloe Cup holders arrived in Sydney on Sunday evening, six days before their match at Sydney's ANZ Stadium.
Hansen continued his complimentary assessment of the Wallabies, rating them "a really good side" after their three-test home series loss to Six Nations champions Ireland.
"They won that first one and the second two games they didn't get much luck did they, so it could have gone either way that series," Hansen said.
"I thought they got a lot of intensity, they played with a lot of skill."
