From my time, Warwick Angus, Ian Herman, Sean Ralphsmith. They've had some higher profile ones since.
I played at the same junior club that Warwick Angus played at, he was a few years older than me.
The only AFL player that I know of who went to my high school was Adam White, he played about 40 games for Carlton in the late 90's. He was the year below me but I played footy and cricket with him (good basketballer too), nice bloke too
