A 93rd minute goal to Mitchell Duke saw the Central Coast Mariners rob the Jets of a point in their opening round clash at Central Coast Stadium.
The clash seemed destined to finish as a draw, with neither team providing significant pressure to the opposing goal, until a long range Glen Trifiro free kick fell to Duke in the six yard box, who out-muscled Newcastle defender Taylor Regan and placed the ball into the bottom corner.
The result extends the novocastrians losing run against the Mariners to seven, while their record in Gosford has blown out to just one victory in 17 attempts.
Meanwhile, the yellow and navy recorded their first opening round win since 2010, and will take confidence into their Tuesday night FFA Cup quarter final clash against Palm Beach.
Hot conditions on the Central Coast meant that neither team could maintain periods of dominance across the park.
Newcastle's off season aquisition Johnny Steele provided the most significant positive pressure for the visitors, and should have given the Jets the advantage 10 minutes after half time but his 30-yard lob cleared the cross bar after finding himself one-on-one with Liam Reddy.
Senegalese international Malick Mane proved the most dangerous for the home side, making numerous powerful runs and having one shot cleared off the line.
Mariners coach Phil Moss told media at the post match press conference that he was pleased by the endeavour of his side.
"It was a tight game, it was physical - middle of the park particularly and both teams had their chances to win the game today but I'm just so proud of my boys to keep the belief until the 94th minute to grab a goal."
