The Socceroos are ready to silence their American doubters with actions not words, as US players insist they won't get caught out like "overconfident" Turkey.
Australia have one foot in the knockout stage after a brilliant opening 2-0 win over Turkey ahead of facing the co-hosts, who lead Group D after beating Paraguay 4-1 first-up, in Seattle on Friday (5am Saturday AEST).
Tensions have been simmering since December's draw when American pundits started writing off Australia, including CBS pundit Mike Grella who described the fixture as a "lay-up" for Mauricio Pochettino's team.
Ahead of the Turkey clash, Grella indicated it said something about Australia's quality that Nestory Irankunda was their best player.
Irankunda then scored a wonderful goal and dazzled in that win.
