Australia had taken a 22nd-minute lead on the counter attack, as a Lisa De Vanna run and cross set up Chloe Logarzo to score.
Although the USA had the better of the game and its chances, they had to wait until the final minute to rescue a point.
Megan Rapinoe delivered a corner kick and Lindsey Horan headed home for a dramatic finish and 1-1 draw, which left both sides on four points with one round of games to go.
Thursday’s final games are in Bridgeview, Illinois, where Australia and Japan are first up, followed by USA taking on Brazil.
