Graham Arnold made one change to his Australia team for Wednesday's Group D clash with Denmark as they attempt to reach the last 16 of the World Cup for the first time since 2006.
The Socceroos sit second behind France, two points ahead of the Danes, and will go through with a win, or a draw if Tunisia don't beat the world champions in the group's other fixture.
Danish coach Kasper Hjulmand has switched things up for the decisive fixture with three changes from their narrow defeat by France.
Martin Braithwaite replaces Andreas Cornelius up front and Andreas Skov Olsen comes in on the right-hand side of attack.
Mathias Jensen steps into midfield in the place of centre-back Victor Nelson as the Danes switch to a four-man defence.
A second-round tie with the winners of Group C likely awaits for whoever prevails at the Al Janoub Stadium.
