I disagree. The Cricket, AFL even A-League at points have created some solid game day atmospheres. Sport is an entertainment property, you need to create and sell an experience. Big name musicians do it all the time, including authentic audience participation.
I'm from Latin America, mate. I know how is a proper sports environmet, believe me.
Maybe the AFL is a bit better but not good enough for me. It's cultural, AFL supporters attend more than NRL supporters, don't even bold to compare with rugby fans. They are more passional, absolutely. Maybe the Victorians are a different specie of Aussies. I have not idea cause I never lived there, I went just one time as a tourist. But I know how is the average Joe from NSW and they are calm and cold people.
You can see here, Latin American football forums are a completely mess. Fights, brawls, etc, etc everyone insult the players, coaches. G&GR is a peaceful environment, cause the average rugby fan in Australia is that.
You can't expect something like that at the end of a rugby match in Australia:
The people is completely different than the passional Islanders. Not even when the Tahs won the Super Rugby title beating the mighty Crusaders you saw people running into the field
