McKenzie says the blockbuster billing is tailor-made for hype and expectation to go through the roof, with outspoken All Blacks coach Steve Hansen a likely ringleader.
"I noticed he was sprightly against England [last week], so he's warming up, yes," said McKenzie.
"Coaches like myself who don't have to run on the field might say things at times to make things interesting ... the talk ends up getting done by people that don't have to actually go out there and play the game.
"We're going to have to put up with lots of people talking and speculating about our prospects.
"It won't be coming from us."
Australia's current winning run is the longest since the Wallabies were last world champions in 1999-2000, and the impact of Israel Folau and Will Skelton against France suggests Australia may finally possess the strikepower to end a dynasty.
McKenzie said there was every reason for Australia to believe that a slice of history could be within reach after the clean-sweep over France.
"There's no mortgage on these sorts of things," he said.
"They've obviously dominated for a period of time and they're not going to hand it over. We've got to go out there and win it. We've got to get everything right."
McKenzie didn't even wait until Sunday morning to fly his players home, with the focus now back on the end of the Super Rugby season.
Australia won't be thinking too far ahead until they know exactly what personnel they'll have available when they reassemble for the Bledisloe and Rugby Championship in August.
McKenzie is pleased with the consistency and self-belief of his squad, and is relishing a chance to properly prepare his side after last year being appointed just two weeks before the first Bledisloe test.
But he warned a lot can change before his players come back.
"Fitness will be a big part of the equation for both teams. Kieran Read has missed a lot of rugby, for instance, that's an example that you can have great players that suddenly aren't there," he said.
"We've developed our depth and different types of options. Sam Carter should be back, Joe Tomane will be available, Luke Burgess has come back early and Will Genia is a chance.
"We're preparing ourselves as best we can but you still have to face the music on the night."AAP
