I think potentially having some of the big Sydney teams deliver would help. Teams like the tigers and dogs have huge fan bases but have just been shit for too long. Hell just give some of these teams a sniff of the top 8 and we might see some decent crowds.
I think the trick to increasing crowds will be to increase the crowd when things arent so good. There will always be people who attend when teams are winning, and tbh I dont blame the so called band waggoners. You wouldn't keep going to a restaurant and paying $100 if the food and service was sht.
Convincing more people to be full members and making it cheaper so if the games not great you dont feel ripped off are big ones in bringing that lower crowd threshold up. Clubs that are having a poor year having game day promotions and ticket enticements would also help.
Secondly getting away fans to games for those in Sydney v Sydney games. If we say every club has around 12k committed fans who turn up regardless of form then getting half of them at least to away games would make a big difference. Scheduling, venue choice and reciprocal memberships are two ways that can be achieved. With 5 Sydney clubs now playing games at venues under the same SMC its time to be negotiating. SMC benefits from food and drink sales, slice of corporate sales the more people in the stadium.
Despite a pretty good year coming off covid the avg will still be sitting at just above 15k, it hasn't really moved more than a fluctuating up and down 5-10% per year in 20 years.
