With the whole Kidman thing and the Bears I thouht it would be interesting to find out clubs number 1 ticket holders/famous supporters. I'm sure Jennifer Hawkins is the Knights, if not number 1 she certainly supports them. These are some I know, though I don't know the number 1 ticket holders.
Souths - Ray Martin and Andrew Denton
Bulldogs - Harry Kewel
Manly - Sarah Murdoch, Matt White, Ian Ross, Chris Bath
Brisbane - Andrew Simmons and Karl Stephanovic maybe K Rudd
GC - Anna Bligh
St George - John Howard and Morris Iemma
Melbourne - Molly Meldrum
Knights - Hawkins
Those are all I can think of right now.
