Former champions Spain took a 10th-minute lead through a well-taken Angela Galvez strike.

Elena Vizuete doubled their advantage six minutes later with an exquisite looping header from distance.

Spain were awarded a penalty midway through the second half, when substitute Maria Aymerich was brought down in the area and Galvez stepped up to coolly convert the spot-kick in the 66th minute for her brace.

Australia pulled a goal back two minutes later through a neat curling effort from Frida Karaberis but it proved to be a mere consolation.
