The cross-Tasman rivals clash in the inaugural Rugby Championship opener tomorrow.
And Carter reckons the key to kicking-off the competition with a bang will be keeping the Wallabies scrum-half under wraps.
"He sparks a lot of their attack and he's shown on many occasions what he's capable of," said the World Cup winner.
"He's a real attacking weapon for the Wallabies so we've worked hard, especially with our forwards around the breakdown, to make sure we're always sound in those areas to stop his running game. If he gets that going it can be a tough night at the office.
"Every time we've had success against the Wallabies we've managed to nullify their strengths and I guess Will's running game is definitely one of them."
Despite clinching last year's Tri-Nations title, the Wallabies are desperate to end their Bledisloe Cup pain, having failed to claim the trophy in almost ten years.
They had an extra week's training after their Super Rugby franchises failed to reach the finals and Carter reckons they will be raring at the bit.
"They've been working together for the last three weeks now and we've only been together for just over a week.
"They've been training pretty hard together and building a lot of combinations and working towards this one game so they're going to be really hungry," said Carter.
"They're already talking a lot about the Bledisloe Cup which they haven't had for a long time and they will be confident they can beat us over there in Sydney.
"We're going to have to start well to stop them and put some doubt in their minds."
"Their backline is extremely dangerous. With the likes of Digby Ioane, Kurtley Beale they can really open up teams if given time and space so we really have to shut down a couple of those guys."
But Carter is confident that the All Blacks own giant backline can cause the Wallabies some serious problems of their own, providing they can secure a sufficient platform.
"We've got some real attacking weapons in the backline, in particular, Sonny Bill (Williams) and Ma'a (Nonu) who are dangerous with the ball in hand," said Carter.
"From my perspective I'll just be looking to give them as many opportunities as possible and look to feed off them because they are quality players and massive men who can give us good go-forward.
"It's pretty awesome looking outside and seeing those two, they're huge."
