She was hot favourite and with long-time jockey Hugh Bowman in the saddle there was only ever going to be one victor, cementing her place in horse racing history alongside fellow Australian greats Phar Lap and Black Caviar.
The win was not only a milestone moment for Winx but also for trainer Chris Waller, who picked up his 100th Group 1 victory following Verry Elleegant's success in the ATC Oaks earlier in the day.
Winx's victory took her winning sequence to 33, her tally of Group 1s to 25 and sent her earnings past the $26 million barrier. With less than a half mile to run, Bowman made his move to the leaders, swinging four wide at the top of the stretch as jockey Tommy Berry got a dream trip along the rails aboard Kluger, saving all the ground and taking a narrow advantage at the top of the straight.
It came at around the 800m post and once they straightened Bowman gave a little nudge and into the lead Winx went and the rest, as they say, is history.

"The public realize the incredible history they have witnessed today". "Because I tell you there are times I haven't wanted to. But thanks for appreciating her for what she is".
