If you look to the Worlds *best* football stadia - anfield, Amsterdam arena, juventus, celtic park etc these are all 50-60 ish k arenas. World famous, amazing atmosphere, look sensational on tv and tourist destinations in their own right. My point is thats how you make a football stadium perfect for NRL - and Sydney crowds .Even the superbowl is often a 70-80k. Football isnt supposed to viewed or played on cricket grounds.I feel the narrative gets skewed in this Country. Lower cap might also makes tix harder to get therefore encouraging more attendance .
