A brace from Michelle Heyman has lead Canberra United to their first win of Westfield W-League Season 10.
United fell behind after taking the lead as Kylie Ledbrook scored twice from the penalty spot, but rallied infront of a bumper home crowd to steal the win inside the final 10 minutes.
The visitors came out of the blocks fast as they looked for their first win of the young season, and Princess Ibini had a good chance after 40 seconds but she fired her effort wide, unmarked at the back post.
Lisa De Vanna had a chance two minutes later but she sprayed it high and wide as Ante Juric's side turned the screws.
United took the lead somewhat against the run of play, as Ellie Carpenter got free down the right hand side on a counter attack.
The Matildas full back crossed to Ashleigh Sykes who had her shot blocked, only to see the ball fall to Heyman near the left edge of the box.
She played a return pass to Bethany Gordon, before rifling her shot across Khamis and just inside the post to give United the lead.
The hosts began to push for more as the half wore on, but just as it looked like they would take the lead into the break De Vanna went to ground in the box, and Ledbrook stepped up to slot home from the spot on the cusp of half-time.
De Vanna had a big chance early in the second half as she weaved through the defence, but the excellent Kopmeyer did well to save down low.
The two sides traded efforts early in the half and Kopmeyer saved well a number of times as Sydney tested the home backline.
Carpenter continued to trouble Sydney down the right flank and create chances with her link up play, but it was the visitors who took the lead as a penalty was whistled for off-ball contact at a corner.
Ledbrook stepped up and fired home but was forced to take it again, and just beat the outstretched Kopmeyer as the Sky Blues took the lead.
United looked to respond strongly though, and substitute Caitlin Munoz helped to orchestrate proceedings on her return to the Westfield W-League.
With less than 15 minutes to go a corner was brought to ground by Heyman, and Toni Pressley was on hand to poke the ball home and grab her first goal for United.
The momentum was with the hosts as time wound down and another corner presented the chance to find a winner, and Heyman found space at the back post to tuck the ball past Khamis in goals and steal a famous victory for United.
The reigning Premiers jump back on the road next week to Newcastle while Sydney will face a Melbourne City side fresh off a 5-2 thumping of the Jets.
