The best way is through AFL Travel. They have Grand Final packages on sale for a $2000+. BTW, no Grand Final tickets are sold to the general public, or to members of clubs not in the GF. Only a very limited number are available to members of the 2 competing teams. The rest go to the corporate world who contribute vast amounts of money to run the game, and hard core AFL fanatics (AFL members and MCC members) who pay thousands of dollars over the life of their membership for the privilege to go into a ballot for tickets each year. This after spending decades on a waiting list to be upgraded to full AFL or MCC membership.
