Tom McLaughlin rode him to glory in the showpiece race of the final day of the meeting, with the 4-1 shot coming past 9-4 favourite Harris Tweed late on to seal the win.
It was a triumph for trainer Ed Dunlop, who hailed the progress the horse has been making since he was a runner-up in the 2011 Melbourne Cup.
"It's a big day for the horse and the team. He's been a star for all of us and it's fantastic," said Dunlop.
"He's a gentle giant. He doesn't worry about life and he's improved phenomenally as he's got older.
"I'm very proud of the horse and the team and I'm particularly pleased for Tom as he's been a huge part of this horse's career."
