I would think that the turnout from our supporters was about the same as for the Fremantle game. So perhaps roughly 18k Melbourne, 5k Fitzroy/Brisbane? The MCC's estimate of 20,000 was just a touch conservative, but, understandably so.
However, the Bulldogs pulled 39,320 vs Brisbane (Melbourne Cricket Ground on Saturday, 14th June, 2008).
Only one of ours comparable to that would be vs West Coast (35,653 at Melbourne Cricket Ground on Saturday, 18th June, 2005). Both teams flying at that stage.
Or if you count the Sydney one a while back that was some sort of Tony Lockett milestone (52,614 at Melbourne Cricket Ground on Monday night, 24th August, 1998).
