As part of the weekend, Williams will join ACC to talk about preparing for games and how to prevent injury.
ACC's injury prevention portfolio manager for sport, Isaac Carlson, said Williams would be taking part in a "skills and drills" session with the ball boys and girls at 2pm tomorrow, followed by a crowd walkaround.
On Sunday he will be at the ACC tent from 11.30am for about 45 minutes signing autographs and for people to get snaps.
