"The AFL Membership product is not a club specific product. Regardless of which club you support, AFL Membership provides access to NAB Cup matches, 40 Home and Away matches and access to Finals ticketing. By selecting a club of support, allows you to contribute to your club financially."
"The AFL Membership package is based on access to matches at the MCG and Telstra Dome as these are the only two venues in Australia that have an AFL Reserve. As the interstate clubs control the seating arrangements for their home matches, only AFL Members holding a club support package of the home team will have entry rights, as their Club Support fee contributes to the gate admission costs."
It seems answered to me.
