CJ you're kidding right?
Because BSA actually spent money to build Wayville, Forestville has received one benefit after another. Some would say Forestville's current success has a lot to do with the venue BSA has given it as a home. (Just think about the Men's ABA success built from Bar revenue as an example.)
Lightning games, Junior finals every season and now Grand Finals, every tournament BSA run such as SAPSASSA Finals, Masters Games, Special Olympics etc.
All events at which Forestville makes money for no reason other than it just happens to have BSA allocate that venue to Forestville as it's home.
Does it pay for having the best venue in Adelaide? No. It pays just the same court hire as North or South do for Hillcrest and Marion.
Does it pay to have the most usage in its stadium which leads to the highest customer base for its canteen and bar. No. It pays $0 for the canteen and bar yet makes thousands of dollars from both.
Every club in Adelaide would love to have been gifted the venue, events and now Grand Finals to make revenue from that Forestville has. Even if it meant losing its courts and income for 4 weeks of a 52 week year.
