He was adamant Australia could fix the defensive problems in the space of a week.
"Quite easily," Grey said. "A lot of defence is mental application and that real will and desire to want to get in there and be effective. In terms of training, we're going to be really focusing on that."
Grey made it clear the Wallabies had been stung by the decisive defeat, but were determined rather than daunted by the challenge of trying to beat the All Blacks in Wellington.
"It's certainly going to fuel the fire for the week," Grey said. "We're disappointed, certainly our pride has been damaged. But the great thing about sport is, [coach] Michael [Cheika] said it in the changing room, we've got six days to turn things around and Saturday night can't come quickly enough. We really want to make sure that we can put in a performance that we're proud of."
As the defence coach, Grey admitted he took conceding so many points last Saturday personally. "It's certainly something I pride myself on, in terms of the team and certainly feel disappointed."
