Hi Chelsea,I wonder if you want a local teams either Adelaide Crows or Port Adelaide.If so you should be able to get one at either club or through AFL merchandise stores for any team you like.A large one should be about $16 or $18.You might be best making a few phone calls to AFL sports stores in and around the Adelaide area to make sure they have what you want,good luck.
I know with my club (Geelong) that it's possible to ring their store and send them cash or cheque (if you don't have a credit card). Not sure if that would help you. Otherwise the answer above is pretty good.
