The USA will top Group D provided Türkiye do not beat Paraguay later in the day.
Australia could qualify for the knockout rounds with a second-or third-place finish.
Türkiye and Paraguay lost their opening games and are playing later today.
If the match is a draw, Australia will remain in second place.
If Türkiye win, Australia will remain in second place because they hold the head-to-head tiebreaker over Türkiye after beating them 2-0 in their opening game.
If Paraguay win, they will move level with Australia on three points, but Australia will remain second unless Paraguay win by four or more goals, which would put them ahead on goal difference.
The final standings will then be decided in the final match.
Australia will take on Paraguay next at 12pm Friday 26 June (AEST).
If Australia can stay in second place, the Socceroos will face the second-placed teams from Group G (Belgium, Iran, New Zealand or Egypt).
If they qualify for the Round of 32 as one of the best third-placed teams, it becomes hard to predict their opponent because that will hinge on what happens in other groups.
