The Newcastle Jets ended their marathon goal-scoring drought but remain without a win after four rounds of the A-League following a 2-2 draw with defending champions Central Coast Mariners.

In front of a crowd of 13,744 at Hunter Stadium, defender Scott Neville ended the Jets’ barren streak at 457 minutes when he was on the spot to tap home a blocked Adam Taggart shot in the 51st minute.

The Jets went two goals up five minutes later through an own goal in embarrassing circumstances for the Mariners. Goalkeeper Justin Pasfield missed a back-pass which just crossed the goal-line before he could clear it under pressure from Taggart.

The Mariners were back in the contest in the 64th minute via a penalty after teenage Jets defender Connor Chapman hand-balled a cross from Joshua Rose.

Marcos Flores scored from the spot but was forced to retake it after teammates encroached on the area early. He made no mistake with the second attempt.

The visitors then equalised in the 80th minute when Mile Sterjovski found an open goal after a mis-hit Flores shot rebounded to him off the crossbar.

The result leaves the Jets on three points and the Mariners on six.

Earlier, Perth Glory escaped with a 1-0 win over under-fire Sydney FC at nib Stadium after a botched offside call led to an early penalty.

Sydney came to Perth desperate for points following disappointing losses to the Brisbane Roar and Western Sydney Wanderers, and more than held its own against the Glory in the warm afternoon sun, but a crucial call in the opening minutes was the difference.

Glory attacker Ryo Nagai was clearly offside attempting to run onto a lofted pass from Jamie MacLaren.

With the linesman allowing play to go on, Sydney goalkeeper Vedran Janjetovic cannoned into the back of Nagai and caught him high, with the referee having no option but to point to the spot.

Steven McGarry coolly slotted home the penalty in the ninth minute to give Perth the lead and the score would stay at 1-0.

The Sky Blues had the better of the opportunities for the remainder of the match.

A long-range Marc Warren effort almost curled into the top corner, Nicky Carle had several chances on goal, as did Richard Garcia.

Glory goalkeeper Danny Vukovic was outstanding in keeping Sydney from scoring.

The pressure continues to mount on Sydney and coach Frank Farina, with just one win from their opening four games.

Alessandro Del Piero came back from injury for Sydney off the bench in the 62nd minute to replace Carle, who had an outstanding match for the visitors.
