Australia were held 1-1 in Perth by Slovenia, who equalised in stoppage time despite losing the first of the friendly double header 3-0.
Ellie Carpenter had provided the ball from which Michelle Heyman opened the scoring five minutes after the interval but the home side could not find a second goal for the 13,000 crowd.
Mackenzie Arnold had made a save in the last minute of the 90 from Mirjam Kastelec, as the Matildas side struggled to keep out multiple efforts by Slovenia.
But the leveller did soon follow, as a shot from Naja Mihelic came back off the near post and Kastalec was first to the loose ball to ram it home.
Ecuador struck four times in 15 second-half minutes for a 4-0 result over Guatemala, Nayeli Bolanos and Danna Pesantez with two goals each.
