Closing off vulnerable areas close to the ruck was an important lesson for the All Blacks looking to build on their Bledisloe Cup clean sweep as they head into their remaining Fortinet Rugby Championship games over the next four weeks.
Coach Ian Foster said Australia had analysed the ruck area well and liked to attack in those inside channels and caught some of the All Blacks' edge defenders wide in the 38-21 win.
It's an area the All Blacks would need to keep growing, one of the few in their defensive approach that was so outstanding on the day.
Foster was impressed with the side's desire to play and to look for opportunities to attack with and without the ball.
They demonstrated their commitment to the Championship, something Australia coach Dave Rennie had questioned.
"It came down to our defence. We put them under a lot of pressure through our defence, and we forced them into some errors. We forced them into some loose offloads, and we were able to pick up a few plums there as well. So hats off to Stormy and the work he's doing with the guys, and the desire of Ardie and the group to commit totally in that space.
"It wasn't a picture perfect game in many ways but the attitude and the commitment to run, and scramble, I thought was outstanding," he said.
They were composed when suffering the red card to fullback Jordie Barrett, and when skipper Ardie Savea left with a head injury. That composure continued from vice-captains first five-eighths Beauden Barrett and lock Brodie Retallick.
Foster said he was 'pretty surprised' by Barrett's red card, and they would be putting a case together to present to the judiciary on it.
Barrett had lost balance, and he tilted, and it could be seen what happened. Foster didn't think a technique problem was involved in the incident.

Foster said the 20-minute law used in the Fortinet Rugby Championship had demonstrated its worth around such a contentious red card.
"It's why all the Sanzaar countries are pretty united in wanting to carry on this global trial. We were a keen supporter before the games and I think today's thing probably justifies it," he said.
The completion of a Bledisloe Cup clean sweep meant a lot to the side.
With the changes required beforehand, and the replacements needed during the Test, the selectors were rewarded for their earlier decisions to give players time on the field, as their depth proved invaluable.
"It's a squad that has worked hard to get role clarity, we're getting there, and let's fa
