Hmmm, that figure seems wrong. Pretty sure the current Fox deal is around $58m a season.
EDIT: EG The figures are from the FFA's annual participation report and are derived from state federation registration statistics. The latest one was released overnight and it shows that Victoria's thrust to increase the number of registered players is working with 6k extra players in 2019 taking the penetration percentage up to near 1.2%. I hope that continues and growth increases.
If you look at attendance at games in Victoria your claim that you attend the A-League in higher numbers is hard to accept. Victory has good attendance but both City and WU don't.
Population in Victoria is growing faster than in NSW but the population is about 1.8m lower. Melbourne will overtake Sydney in the near future but with registration in Melbourne being one third of that in Sydney at the moment the benefit to the overall game will be relatively slow.
