In one of the matches of the season, the Sky Blues looked on course for a huge win over their bitter neighbours as an Ante Covic own goal and a brace for Mark Janko had them three goals up inside 25 minutes.
But spurred on by almost 20,000 fans at Pirtek Stadium, the Wanderers produced a stunning fightback with Iacopo La Rocca and debutant Kerem Bulut getting them back in the contest before the break.
Bulut became an instant fan-favourite when he equalised nine minutes after the break but Antonis had the final say, coming off the bench to pinch a winner and move Sydney FC into the top four, despite Mickael Tavares seeing red seven minutes from the end.
It ended the Roar's three-match winning streak as Glory's winless streak extended to six games.
In Saturday's early game, the Newcastle Jets and Central Coast Mariners played out a turgid 0-0 draw.
