The Sydney Swans VFLW side have gone down in heartbreaking fashion, suffering a two-point defeat to Collingwood in their final game of the VFLW competition.

It was a remarkable final 90 seconds, where Collingwood kicked two majors in the dying stages to mount a thrilling comeback at Tramway Oval in Sydney.

Where most clubs have rested their best players against the Swans and GWS Giants, the Magpies brought seven AFLW stars into their team and grabbed a vital four points that could end up being crucial in deciding whether they make the finals.

SYDNEY SWANS        2.0        2.1        5.2        5.5 (35)
COLLINGWOOD         1.3        2.5        2.5        5.7 (37)

The loss is Sydney's first defeat in their five games of the rebel VFLW competition. It was a tight contest for the entire game and the visitors found themselves within 10 points with two minutes to play, having kept Sydney goalless in the second and final quarters.

Sarah Sansonetti took a mark at half-forward and received a 50m penalty before slotting the goal with 88 seconds remaining.

From the resulting centre bounce ruck Sabrina Frederick found Muireann Atkinson, whose long bomb to the top of the goal square found its way through to Kaitlyn Day, who gleefully nailed the match winner with the last kick of the game.

The Swans usual fast start that was on display in their previous games was stifled by the Magpies, with the red and white kicking just two goals in the first quarter, including one to QBE Sydney Swans Academy product Emma Juneja who showed some individual brilliance to score the side's first of the afternoon.

The Magpies fought their way through the second term to lead at half-time by four-points.

Sydney looked like it had broken the shackles with three goals in four minutes midway through the third to lead by 15 points turning for home, with goals to Holly Cooper, Montana Beruldsen and Sarah Grunden.

Sofia Hurley put in a lion-hearted effort for Sydney with 18 disposals, 16 tackles and seven inside-50s, with Eliza Vale (22 disposals, seven marks), Montana Ham, Ella Heads (eight rebounds) and Lisa Steane all having 20 touches each and Tanya Kennedy sticking 10 tackles.
