Nehe Milner-Skudder was a rare bright spark for Hansen's side, the winger scoring a pair of tries on his Test debut.
However, Sekope Kepu, Adam Ashley-Cooper and Nic White each touched down for the Wallabies as the combination of Michael Hooper at openside and David Pocock at No.8 saw them win the back-row battle.
Following that 27-19 defeat, the two sides will reconvene on Saturday at Eden Park - the venue of two Test clashes with the British & Irish Lions in 2017 - with the winner getting their hands on the Bledisloe Cup.
"There are a lot of things we can improve on. The big thing is we can't afford to panic.
"We have a plan that we are playing to and this week we have to make sure we get the critical few things right and adjust one or two things we are doing and get better at it."
