The Westfield Matildas have scored another win overnight defeating Singapore, 6-0, in the ASEAN Football Federation Championships being held in Ho Chi Minh City, Vietnam.
Australia has finished top of its group and is now through to the semi finals.
Played in humid conditions with a slight breeze, the Westfield Matildas have scored a hat trick with three wins out of three games.
Westfield Matildas got off to a good start with Colthorpe shining in the first half and scoring a goal in the 6th and 22nd minute.
With Rollason off at half time due to injury and replaced with Mastrantonio, Australia started applying pressure again from the beginning of the second half.
In the 51st minute, Butt delivered a great ball in from the corner to centre goal, which was touched in from close range by Sykes.
With Sykes work done, she was substituted for Tristram in the 58 minute. Then within nine minutes Balomenos connected with Colthorpe who ran in through the box, across to Tristram to score a neat low finish from 10 metres out.
With Khamis on and Walters off, shortly after in the 78 minute Balomenos raced in and scored Australia’s fifth goal of the match.
A free kick centre field from 35 metres out saw Colthorpe tap the ball to Mastrantonio, who delivered a solid, crowd pleasing shot that flew into the top right corner.
Coach, Alistair Edwards, said Australia’s overall performance was excellent – with the team controlling the tempo from start to finish.
"We were able to try different players in different positions, and also to change our system of play as the game progressed to try to counteract Singapore's defensive approach.
"Our first target of making it to the semi finals has been achieved - everyone has contributed to us getting this far.
"It's pleasing for the future of our game that our two youngest players got on the score sheet today," said Edwards.
Australia is through to the semi finals on Saturday, with opponent yet to be determined.
