On a sunny afternoon in Melbourne 30 years ago, Aussie Rules footballer Nicky Winmar defiantly stared down a bitter crowd hurling racist slurs, spit and drink cans at him.
Lifting his shirt, the Aboriginal man pointed at his skin and shouted at them: "I'm black, and I'm proud to be black."
That Saturday afternoon at Victoria Park would go down in Australian sporting history. Many hoped it would change the Australian Football League (AFL), which had been turning a blind eye to rampant racism.
