Brisbane, Melbourne, GC, Souths, Canterbury, Tigers. Dragons will always be lower unless they take more games on the road as we're hamstrung with both WIN's being around 20K
I believe the new WIN Stadium in Wollongong (stand under construction now) will be near on 25K...
Kogarah already has Development Approval for extensions to the north eastern terrace / grandstand (same as what was added to the south eastern corner) and that should add another 2K or so to a 21K capacity, including an extension to the corporate area might add another 1K or so.
Our biggest issue is the restrictions on selling season tickets. The NRL do not permit a total sell out to members, there must be a portion of reserved seating available to opposition fans. We are at capacity now for reserved seating members at Kogarah, so we can only grow in Wollongong and General Admin until the extensions in Kogarah go ahead (and we need funding).
Personally, I think growing season tickets is the most important thing in the game at present, and I think the rules need to be changed so that clubs can sell every single seat to their stadiums if they can. If that means Kogarah is sold out in advance and it's a lock out for opposition fans so be it. Same at Brisbane etc.... if they have the numbers to force a lock out, then great.
Sports in the USA often have waiting lists of 50 years + to get a membership, and I don't think there is anything wrong with that so long as a system is in place that if you can't make a game, you can put your seats into a resale pool to ensure the game is full.
Season 2011, at this stage Saints will have 12 games in Sydney. 2 or 3 will be played in a bigger stadium IMO
