If you get fine weather sunday 4pm,as the Dragoons v Sharks showed ,you crack 18,000 ,with the hill full as a constipation.
The next test will be similar timing sunday 12th july at Remondis same derby.
That being said ,I would prefer a 20,000 seat suburban stadium,where everyone can be seated on their fat a*ses .
Crowds will attend matches depending on scheduling,and the opponents involved and transport situation e.g. Fridays and Monday nights. are restrictive.
Fact Manly fans will not travel on weeknights,ditto Sharks and Penrith.
According to Kent the NRL will be demanding control over scheduling of matches as part of the next TV deal.That has to be a plus.
Monday nights get the ratings on TV,but drag the crowds down big time.Forget monday nights at ANZ/SFS,concentrate on suburbans and big country towns.
