Wollongong Olympic finished with nine men and their treble dream in tatters after a nailbiting loss to Bulli on Saturday.
Olympic had already claimed the Illawarra Premier League title by dethroning Bulli last week, but the northern suburbs power responded in kind at JJ Kelly Park.
Mitch Del Turco put them ahead with a clinical shot in the 30th minute, before Olympic were left a man short when Brendan Fordham saw a second yellow card an hour in.
Del Turco surged through chasing a second in the 74th minute when he was fouled by Mark Every, who was sent off for the challenge as the last man.
Even with nine, Olympic still almost sent the game into extra-time Yusuke Ueda's strike went just wide in the final minutes. But in a season where they relinquished their crown, are out of the finals race and coach Matt Bailey resigned last week, it was a moment for Bulli to savour some silverware.
Bailey, who delivered Bulli's first grade final win in three decades last season, left after the 2-1 loss to Olympic in the league.
"Matt was going to stand down at the end of the season anyway, but he thought the time was right now and we respect that," president Paul Connery said. "He'll always be highly regarded by everyone at the club, especially for what we were able to achieve last year."
Olympic's focus turns to a two-week tune-up - against Port Kembla and potential finals rivals Wollongong United, before chasing the double themselves, as they lead by seven points in the league.
