So I'm going to be very optimistic here and predict that both the Roosters and Raiders come out of this weekend as our Grand Finalist. As per usual, we'll have our bandwagoners attending, so we should have the same amount of fans attend the GF as last year. Raiders will most likely organise buses etc but how many fans from Canberra will attend? I suspect some neutrals may attend (that haven't already purchased tickets) to watch the Raiders potentially win a GF. But given we (the Roosters) don't have the largest fanbase in RL, I don't think it will be a sell out GF. Maybe a little larger crowd than last year.
In another situation, if both the Roosters and Rabbits win this weekend, then I suspect the GF will sell out due to the rivalry within half a week.
