Not shocked - the stadium was empty on 3 sides and the 4th side would not have been a quarter occupied. At least 50% of the fans were Drua supporters. Just your standard showing by the Sydney Rugby faithful, wedged by complaints over stadium locations and mindless support over a shrinking "Premier" scene that is picking a fight with the money making side of the game.
Can you blame them after last season?
Yes. Yes you can.
If it gets any better at Leichardt I'd be surprised, given the public transport options, dining, and parking are even worse.
I paid my $49 for a decent ticket and was entertained, in a history-making event.
