The 24-year-old All Whites international scored the third and fourth goals in Newcastle’s 5-2 blitz of the Sky Blues at the Sydney Football Stadium yesterday.

He and Michael Bridges combined to create the fifth for substitute Ali Abbas deep into injury time, and Nikolai Topor-Stanley and Ruben Zadkovich gave the Jets a stunning 2-0 lead with goals in the 22nd and 29th minutes after Sydney had dominated the early stages.

Brockie’s brace, his first away goals all season, stretched his tally to eight, one in front of teammate Ryan Griffiths.

Zadkovich, Topor-Stanley and Brockie were teammates at Sydney FC in the 2006-07 A-League season, and Bridges joined the club on loan the following summer. Defender Byun Sung-hwan, who started on the bench, and reserve goalkeeper Matthew Nash are also former Sky Blues.

‘‘We were actually sitting at dinner last night – me, Ruben, Topor and Bridgey – and we were talking about how when you come up against your old clubs, more often than not you score goals, so it obviously came off well for us today. We’re obviously a very happy change room right now,’’ Brockie said last night.

Brockie’s goal celebrations were more low-key than those of Zadkovich.

The Wollongong-born midfielder leapt advertising signs at the northern end of the ground, turned his back to The Cove and pointed with his thumbs to his name and number.

He was showered with abuse – and a few plastic bottles – for his troubles, and was greeted with booing and jeering for the rest of the game every time he touched the ball.

‘‘I just kept mine to a minimum, to be honest,’’ Brockie laughed.

‘‘I saw a couple of bottles get thrown at Ruben so I thought I’m definitely not going that way. I’ll just stay on the pitch and celebrate with the boys.’’

Brockie, who has expanded on his pre-season target of 10 goals, played just seven games in his only season at Sydney and said he had matured as a player since then.
