Wallabies defensive coach Nathan Grey insists there is an easy fix to the tackling frailties that allowed the All Blacks to score six tries in their 42-8 Bledisloe romp on Saturday night.
Michael Cheika's side slumped to their fifth straight defeat at the weekend, the All Blacks cruising to their biggest victory on Australian soil thanks largely to a blistering first half that saw the world champions cross the line four times.
The Wallabies have just five days to remedy their defence before the return clash in Wellington, and Grey said the squad would be spending plenty of time at training addressing both their tackling technique and wider defensive system.
"I think defensively, very disappointing, the Kiwis stressed us out in terms of down our edges and their offload game really hurt us," Grey said.
"So I think being very efficient in our tackle is something that we're going to have to focus on a lot to ensure that we can stop their go-forward and then hence their offloads.
"In terms of our system execution, we were poor there as well. So we've got to make sure that everyone has a clear understanding of what their roles are and the execution within those roles."
While a clearly disgusted Cheika hit out at the Wallabies' defence post-match, the coach also shouldered some of the blame for how he'd prepared the squad mentally.
Grey was adamant the defensive attitude could be fixed "quite easily", saying it was all about desire - something Australia appeared to lack considerably at ANZ Stadium.
"A lot of defence is mental application, and that real will and desire to want to get in there and be effective," he said.
"So in terms of training, we're going to be really focusing on that and having a real clear picture on how we want to defend."
The lineout remains the other chief area of concern for the Wallabies ahead of this week's second Test after the All Blacks stole four balls on Australia's throw in Sydney.
Quizzed about the lineout deficiencies, Wallabies lock Rob Simmons played down the limitations a Michael Hooper-David Pocock back-row combination has on the key set-piece.
"No, I don't think so," Simmons said of the Wallabies' lack of height.
"There's a lot of different things that go into a lineout, and a short guy being lifted by tall guys is the same as a tall guy being lifted by a short guy."
