Cheika added: "We're the enemy here, that's for sure, and that's a great feeling sometimes in rugby - to be away from home and being the enemy and being bound together ..."
Cooper will receive a loud and at times unpleasant reaction from the crowd after his history of targeting All Blacks skipper Richie McCaw in a series of cheap shots.
Cheika will be well aware of that but was playing the innocent card when he said of the Tokoroa-born player and the coverage his selection has already received in the media: "Maybe it's a little bit advantageous for me because I wasn't around when that stuff happened with Quade so I don't really know too much about it.
"I'm not saying this disrespectfully but I'm not here to read the newspaper ... I know we're inexperienced as Australian coaching staff and they've got a much better record than we have ... but I'll back my guys and I don't fear failure."
Wallabies captain Stephen Moore said of the noise around Cooper's selection: "That's all peripheral stuff, isn't it? He's had a good week of training. We've got full faith in him ..."
Cheika refused to take credit for last week's 27-19 victory in Sydney.
Asked if he had out-thought the All Blacks, Cheika replied: "Everyone has a line to throw away - Steve Hansen has won I don't know how many tests.
"He's never been beaten at home, he's been the leading coach in test rugby for many, many years and still is. His team is No1. "One win don't maketh the man. We need to be consistent and playing well."
There were few shots fired by either Cheika or Moore, just as Hansen has been holding his fire this week. Both teams appear to be saving that for tonight.
