The Socceroos will need to go to another level and top their World Cup heroics against Turkey if they are to beat the United States.
That's the message from coach Tony Popovic ahead of a blockbuster, high-stakes clash with the co-hosts.
Australia stunned Turkey 2-0 with a brilliant performance where they were superb defensively then hit their more-favoured opponent on the counter.
But the US, who beat Paraguay 4-1 first up, pose a different test, regardless of whether star attacker Christian Pulisic plays.
"It's a different challenge. Different teams. Turkey were a more European style in terms of their technical build up, slower build-up, fantastic possession," Popovic said.
"I think the United States team has a good mix of the two: very powerful, very athletic, so we know it will be a different type of challenge.
