If there was one lesson taken by the Wallabies from their clash at Eden Park earlier this month, it was the need to harden up.
For all the pretty patterns and clever sleight of hand, the Wallabies couldn't trouble the All Blacks because they were some way off delivering the required physicality in the key areas of the game.
Rocky Elsom, normally a bruising handful, was a bit squishy in Auckland, as were most of his troops. The All Black pack controlled the collisions and, therefore, controlled the game and the Wallabies were sent to Africa with much to think about.
They absorbed the need to be more brutal, more aggressive and more dynamic and, for the first time this season, the Wallaby pack was snarling and impressive against the Boks.
The confidence gained by that win in Durban has been obvious listening to the positive commentary emanating from the Wallabies this week. Whatever they were missing in Auckland, they believe they have found and if their performance gets anywhere near matching their self-generated hype, then the All Blacks are going to have to bring a particularly hard edge to their work.
