Aaron Mooy and Bruno Fornaroli have netted a brace each to sink Newcastle 4-0 and claim third spot on the A-League ladder.
City kept the momentum flowing hot off their record consecutive 5-1 beltings of Perth and Central Coast, with three second-half goals in six minutes against the hapless Jets at Hunter Stadium on Sunday.
The in-demand Mooy was relatively slow off the blocks in this stop-start contest but simply couldn't stay out of the action, while Uruguayan striker Fornaroli ensured his league-high goal record bulged to nine.
It leaves the Jets wallowing in seventh placed, still with an appalling home record and without a win since their remarkable round-four 3-2 comeback win over City.
Newcastle pounced early and created chances though sorely lacked a clinical finish, an all-too-familiar sight that has seen Scott Miller's men score no more than one goal in eight of their past nine matches.
Returning Brazilian playmaker Leonardo won the ball numerous times while Milos Trifunovic, who netted a brace in these sides' last meeting at AAMI Park, penetrated early and dinked a cheeky backheel for Serbian compatriot Enver Alivodic, only for City keeper Thomas Sorensen to scoop up his effort.
But Newcastle's audacious start didn't last long and City stole the edge.
Frenchman Harry Novillo stung the hosts' sturdy defence with a glorious cross that floated invitingly for someone to finish, but gloveman Mark Birighitti was lucky to watch it trickle out.
It was Mooy who delivered the first blow just before halftime.
The 25-year-old flew into the box and toyed with defenders before offloading to Ivan Franjic.
When Mooy got the ball back only Birighitti was standing in his way, and he drove low and hard through the custodian's legs into the back corner.
After the break Birighitti was caught between his pins again when Fornaroli got last touch after a cheap turnover, before Mooy kneed a lovely Franjic cross home four minutes later.
Within two minutes Mooy had set a fourth goal on a plate for Fornaroli, who withstood two defenders with via some fancy footwork before striking.
The Jets toiled and the rejuvenated David Carney was an outlet on the wing, but they were destined for their first loss by more than a goal this season.
Trifunovic, who was offside more than he was on, had opportunities late on but there would be no consolation for the 10,087 spectators.
