Regardless of the seriousness or likelihood of any opportunity, whether it be a 20th team or whatever, South Australia is already somewhat struggling to support 2 AFL teams.
Remember that the State Government invested approx $600M to upgrade Adelaide Oval and gift the management and revenue to the SACA and SANFL in the form of the SMA.
The Adelaide Oval financial model that the SMA manages Is the funding lifeline for the SACA and SANFL, and is marginal at best. Remember that they had to build an onsite hotel to shore up revenue. Any further drop in weekly attendances will only further deteriorate financial returns. This will be a lose-lose-lose for the SACA, SANFL and Port & Adelaide.
Port is not financially viable without AFL and government handouts, whilst Adelaide currently is, but another team will jeopardise this.
South Australia can only sustain a max (and this is the absolute top water mark) of 50K attendance per week (yes, Gather Round will exceed this but that’s basically a one-off exception) This is what the weekly attendances max’ed out at during the halcyon times of the ‘60s, 70s and 80s in the SANFL, and has shown to be the same during the AFL era since.
I understand the romantic notion of having another team, whether it be Norwood or someone else, but the numbers just don’t stack up. There isn’t enough revenue, attendances or critical mass to sustain it here.
Add in the fact the there are already way too many teams in the AFL, with the introduction of the 19th team in TAS (if it actually happens) bordering on ridiculous. Adding a 20th team would be insane. Also the AFL doesn’t need to grow the game any further here, so there’s no financial upside for them in increased TV or subscription media share.
