Skipper Stephen Moore said the side was well aware of the hostile environment that came with playing in Argentina and would be ready for this morning's match.
"No matter what happens ... whether the guy has a few issues with the anthem, there are lasers ... we just need to keep our focus squarely on the job," Moore said. "Argentina is a unique place to play a test. There are all those things at play.
"It's important for us to make sure that, when you get inside those lines, the game is all that matters."
Apart from a 2013 blow-out victory to Australia in Rosario, recent matches between the two countries have been tight.
The Wallabies believe the Pumas have pin-pointed this match as their best chance of a Rugby Championship win and would play their best lineup after their opening 39-18 loss to the All Blacks. But with a swag of changes, including an untested centre combination, they're not sure what the home side will throw at them.
Moore said one thing that was certain was that Argentina would use their set-piece as a weapon against the Australians.
He believed they would also try to target the breakdown, which was a frailty in the last-gasp 24-20 win over South Africa in Brisbane last Saturday night.
"We're not sure if this is their best side or last week is their best side," Moore said. "Their back row was impressive last week and we know they're going to be strong in the scrum. I thought the Boks turned over too much of our ball and we've tried to address that."
Moore missed last year's Mendoza match after knee surgery but said the team had learned a lesson from the loss.
"You can get beaten by anyone," he said.
