Winx has made it 28 straight wins at the Turnbull Stakes.
The champion mare stormed home to win ahead of Youngstar.
"What more can you say? She does us all proud each and every time," trainer Chris Waller told Channel 7 after the win.
"We're very proud of her, proud of wherever she goes.
"It's great to see today's turnout for her. It's pretty special.
"You get a few flutters. But once she had a clear run in, what will be will be.
"There will be a day where she's not as dominant, but today all she had to do was repeat her form, and she did that."
