Venue Capacity
The venue hosting the Grand Final must be able to seat not just members of the clubs, but also key stakeholders, contractual obligations and sponsors as well as AFL and MCC members. Without the club members themselves, the ground must be able to hold a minimum 38,500 people according to the AFL seating arrangements. This alone is enough to rule out Geelong, Gold Coast and GWS from hosting a grand final even without their fans in attendance; creating inequality across the league as these sides would have to find a different venue should they earn the right to host the game. The only venue that can accommodate more than 10,000 fans per team in attendance with these restrictions is the MCG; which the AFL allocates up to 17,500 fans for each participating club, almost double the maximum amount that the next largest AFL venue is able to house.
Revenue
This is not just league officials giving themselves a handy pay day for a job well done, the generated revenue from grand final day goes directly back to the players and clubs. Linking in with capacity, if AFL members and contractual obligations were not offered seats to the game, than the leagues revenue would vastly diminish. Additionally, if more people are attending the game it appears more marketable. Therefore, more sponsors will want to be involved in the event and as a by-product the game itself. This is the most watched game of the league season and the larger ground of the MCG makes the product appear more valuable than Spotless or Skilled Stadium would be able to. This not only maximises profit from ticket sales; but would increase the sponsorship opportunities of the league, allowing it to grow and seeing all clubs benefited.
Certainty
The certainty of playing at the MCG gives the AFL plenty of time to plan. With the Grand Final at the MCG the AFL can organise the fixtures to ensure that each team is able to experience the venue before finals. The AFL, however, cannot fixture every team to every venue year in year out ensuring each team has experience there before finals. This gives every team the opportunity to experience the venue before finals as well as keeping the fixtures as equal as possible for all clubs. Additionally, planning the pre-game and half time entertainment without a set venue will be extremely difficult for the AFL. If the venue was undetermined the league would have to ensure all venues are available to them before the season starts. With this uncertainty of whether venues will be accessible and which venue will be used, organising high end entertainment will be extremely difficult. Should the league only know one week before the grand final where the event will be held, requesting guest appearances from global entertainers will mostly be disregarded due to a lack of organisation.
Top Teams can win anywhere
Much of the argument for the Grand Final moving away from the MCG is the disadvantage of interstate sides. As much as fans may not like to hear it, regardless of advantage good teams can win anywhere. Since the competition went fully national in 1986, interstate sides have won 8 of the 14 Grand Finals against Victorian teams with 3 of the 6 losses in the last 3 years. As much as people complain about the Hawks premiership last year, they had to qualify for it on the road and if the Eagles were at premiership standard they certainly would not have lost by 10 goals. With clubs such as the Bulldogs and Kangaroos having played on the MCG less than some interstate sides since 2012, the ground is not an automatic advantage for Victorian sides. Sides such as Brisbane (2001-2004), West Coast (1991-1994 and 2005-2006) and Adelaide (1997-1998) are proof that the very best teams will win the premiership, regardless of where the Grand Final is played.
In spite of any of these arguments for or arguments against, the Grand Final will remain at the MCG until 2037. Perhaps if the national venues grow and develop rapidly enough the competition may be ready for a travelling Grand Final. However, until then the Grand Final will remain at the MCG to the pleasure of some and dismay of others.
