There are a couple of famous Parra supporters already. Bob Hawke declared his hand during the halcyon days; there is a former Miss Australia that was at the 1988 GF when the President's Cup played and said that was the only game she was interested in; Mark Bosnich once said his dream was to play footy for Parra; Jon English sang the club anthem (rock version). I am sure there are many famous 'westies' out there who grew-up watching the Eels e.g. Harry Kewell, Paul Hogan, Toni Collette etc.
P.S. Jack Newton was a parochial Eels fan until he moved to the Hunter and now his son Clint is in the Knights side.
