Nowhere near that much
The league’s first so-called festival of football was held last year, and a deal with the South Australian government reportedly worth $15m annually was extended until the end of 2026
To this you would add the stadium profits... AFL get the gate receipts, catering fees etc less expenses.
All up it gives each club extra revenue of around $800k is my guess
