Ashley-Cooper said it was tough to swallow the fact that he might never hold the Bledisloe Cup, which has eluded Australian hands since 2002.
"You win some, you lose some. That's what a career's about," he said. "My focus now moves towards the World Cup. I'll put that one behind me but use it as fuel and hopefully do some special things over in England."
Five-eighths Quade Cooper felt equally gutwrenched as he watched the All Blacks tear apart a 14-man Wallabies team from the sidelines, knowing his yellow card offence on Aaron Smith had cost his side a shot at victory.
But despite failing to get it done in his intense Eden Park examination, he still firmly believes he is the man who can deliver the goods for Australia when the world's gaze turns their way in England and Wales.
"Of course. I've got confidence in myself and the team," Cooper said.
"We're working very hard to have something special here, on and off the field.
"This team is bonding together very tightly and for myself personally I'm continuing to work as hard as I can to make sure I can perform on the big stage. I felt while I was out there I was able to do everything that was required of me.
"I felt I was getting better and better."
