One thing to consider for next season's breakdown:
We probably won't be playing the following clubs twice at home:
Perth
Brisbane
Adelaide
Heart
We typically get rubbish crowds against Perth, Adelaide and Heart (who doesn't?). Brisbane have sent a few in recent seasons.
We probably won't be playing the following clubs twice away:
Wanderers
Sydney
Newcastle
Wellington
Victory
The first three will draw big away turnouts, Wellington have nothing much and Victory travel to BT better than we travel to Sydney these days.
Our average was very close to 10k this year, we might be 2k higher next year just because of who's coming to town. Derbies will always bring in more locals as well as the boost from away fans.
Add to this FTA (which in areas like the CC where I'd be surprised if PayTV density is near what it is in Sydney, for availability reasons as much as economic) then we have the potential for growth. But we'll see how it pans out I guess.
