Sydney took the lead in the semi final through Kyah Simon (23') but were pegged back six minutes later by Vanessa Di Bernardo (29') from the penalty spot.

From then on it was all Perth who piled on another four after the break to complete a late season collapse by the Sky Blues.. 

An own goal to Alanna Kennedy (58'), a second to Di Bernardo, plus goals to Rosie Sutton (79') and Shawn Billam (93') capped off a dominant display.

Perth will now face off against the winner of tomorrow's second semi final between Canberra United and Melbourne City.
