On Wednesday, the Albiceleste faced a 3-0 defeat by The Matildas after a tough game for Argentina who fell short in their defending.
There were particularly promising performances from Argentina’s Estefania Banini and Soledad Jaimes, but Australia ultimately took control.
The Matildas, ranked sixth in the world, came through with flying colours, beating the Koreans 4-1 and New Zealand 2-0 to give them a flawless record under new coach Ante Milicic.
Matildas Captain Sam Kerr scored with a header from a corner kick in the fourth minute and Alanna Kennedy made it 2-0 in the 33rd against Argentina. Caitlin Foord completed the scoring with a penalty four minutes into added time.
All four teams are bound for the World Cup in France, with the Cup of Nations designed to simulate a group stage at the global showcase, with three matches in a short timeframe.
In June, Argentina will face England, Scotland and Japan in Group D - a tricky group if they’re hoping to proceed to the knock-out fase.
From now on, the team will be training hard with just 95 days left before the main event.
