Newcastle have claimed their first Australia Cup title and delivered a cruel ending to Heidelberg United's fairytale run with a 3-1 extra-time win in the final.
An extraordinary strike from 19-year-old Oscar Fryer in the 96th minute delivered the Jets silverware in their maiden final under former Socceroos captain Mark Mlligan.
With their first trophy since the 2007-08 championship, Newcastle claim a $50,000 prize purse and a berth in the Asian Champions League 2 competition next year.
Victorian champions Heidelberg, a semi-professional team comprised of tradies, engineers, Uber drivers, care workers and more, previously saw off Western Sydney, Wellington and Auckland FC without conceding.
In front of 10,000 fans in Melbourne, Heidelberg took the lead in the eighth minute through Ryan Lethlean.
The proud Greek-backed club had their chances to win the match and become the first non A-League club to win the Australia Cup.
But Newcastle, who as late as last year were being propped up by fellow A-League clubs, would not be denied - despite being without central defender Max Cooper through illness.
Heidelberg were denied a stone wall penalty in the third minute when Mohamed Aidara was clipped by Jets skipper Kosta Grozos.
But five minutes later, Asahi Yokokawa swung a free kick past the back post where Bergers skipper Ben Collins headed the ball across goal for fellow centre-back Lethlean to nod home.
It sent the yellow-and-black standing room area of Lakeside Stadium into ecstasy, with flares going off and coach John Anastasiadis celebrating with a double fist-pump.
The Jets equalised in the 21st minute when Thomas Aquilina was released down the right and cut the ball back for Max Burgess, the Mark Viduka Medal winner for man of the match, whose sweet first-time shot beat Yaren Sozer.
Jets defender Aleksandar Susnjar flashed a header into the side netting in first-half added time.
In the 74th minute, Newcastle teenager Xavier Bertoncello curled a shot wide then Heidelberg should have re-taken the lead when Yokokawa burst forward but his unnecessarily chipped shot sailed wide.
Sozer denied Daniel Wilmering and Aquilina late in regulation time.
But when Fryer beat Fletcher Fulton, cut into the box then whipped a left-footed strike home, the travelling Jets fans went into party mode.
Heidelberg appealed for a penalty when Susnjar outbodied Akiel Raffie, but their pleas were waved away.
Jets skipper Grozos was sent off for a second yellow card in the 113th minute and Heidelberg substitute Johnny Apostolopoulos received a straight red card shortly after.
Then, Nunes teed up Ben Gibson to ice the game and send the Jets into ecstasy.
