Coming into this round of qualification, the Junior Matildas had yet to concede in four games and had scored 39 goals. While Iran had finished top of their group on goal difference in a close round one. 

Australia was able to build up a consistent attack early in the first half but the finishing product wasn't there.

Credit has to go to Iran though, who knew that the best tactic would be to have as many players behind the ball so the forwards wouldn't have space for a clear shot. 

This became a regular occurrence throughout the game and the only way to beat it was through the Junior Matildas moving the ball around quickly to catch the Iran defence out of position. 

Iran were persistent going forward as well but nothing came of it with poor passing being the ultimate fact for not being able to have a clear cut chance. 

Not long after, Georgia Beaumont opened the scoring after goalkeeper Maryam Abbasi fumbled a shot directly in her path. 

West Australian product Hana Lowry was dangerous down the left-hand side and continuously put crosses in the 18-yard box. 

Ahead of halftime, Australia extended their lead through Grace Taranto, who made no mistake in finding the back of the net after a corner came flying in.  

The second half was much like the first but Iran did batten down their defence which restricted the Junior Matildas further. 

Tijan McKenna sealed the three points in injury time after disposing an Iranian player near the halfway line before taking a solo run towards goal and sliding it home.  

The Junior Matildas now face Vietnam, who beat host hosts Laos 1-0, on Tuesday March 5 at 3pm local (7pm AEDT).
