The Young Matildas have finished Round One of their AFC U19 Asian Championship qualification with a 3-0 win over Hong Kong.
Having already progressed to the second round of qualification the Australians saw nine changes to the squad which beat Lebanon 2-0 on Friday evening.
Meanwhile, Hong Kong had already been eliminated from the qualifiers after two losses.
Australia was able to strike early after what appeared to be a handball in the box from Hong Kong gave Amy Sayer the chance from the spot and she didn't miss.
However, it would take another 20 minutes until the Young Matildas would score again.
Hong Kong forced Australia to shoot from outside the box after several attempts to work the ball into the area ended up in Hong Kong's favour.
While Australia has the ability to score from range, there wasn't enough drive behind shots in some chances and it proved easy for the goalkeeper to save.
Sayer stepped up to the plate and scored her fourth goal of the qualifiers with a powerful strike.
Coming back from the break, Australia had the same issue which halted their momentum in the middle of the first half so it took time to either find ther way in or shoot from afar.
Unlike the first half, shooting from outside the box proved to be difficult so they had to find another way and it came courtesy of Canberra United's Aoiefe Covill.
There were worries for Hong Kong keeper Kwok Ka Yee as she went down after a goalkick with her knee buckling under her. However, after attention from the medical team she was okay.
The Young Matildas finished the first round scoring 23 goals without conceding.
The second round of qualification for the AFC U19 Asian Championship, a 2020 U20 Women's World Cup qualifying event, is set for April 2019.
