It was a hot day making play difficult for both teams, leaving periods of fast paced football followed by long lulls in the play.
Western Sydney could well have opened the scoring in the 12th minute as Camille Levin's cross got past everyone forcing a save out of Eliza Campbell.
The Jets thought they'd opened the scoring just after the 20th minute as Gema Simon hit a powerful strike from close range but it was deemed that foul had taken place in the lead up forcing the goal to be disallowed.
In the 28th minute Emily van Egmond nearly stuck the knife in to her former club as she hit a powerful strike from the edge of the area that was hit right at the keeper.
Linda O'Neill twice could have made it two, being denied by a phenomenal save from Campbell in the Jets goal that kept the match scoreless.
On the verge of half time O'Neill made up for her earlier missed chances as she ran on to a through ball from Heather Garriock and rounded Campbell, allowing her to easily slot home the opening goal and giving the Wanderers the lead at the break.
Newcastle started the second half well, but they struggled to create chances in the early going with the Wanderers still looking the more dangerous side, despite having less of the ball.
The Jets probably should have had a penalty early in the half when Levin just ploughed in to Rhali Dobson but the referee was unmoved, leaving Newcastle stunned.
That missed call haunted the Jets in the 71st minute when Western Sydney doubled their lead as O'Neill beat the offside trap and sent a ball for Catherine Cannuli, who had a simple tap-in to double the lead.
If that didn't seal the match Cannuli's brace did, as five minutes later she made it three, getting between her defenders and heading home Helen Petinos' cross.
