AFL CEO Gillon McLachlan has defended his decision to keep the Grand Final at the MCG on SEN.

The AFL and Victorian government are set to officially announce their $500 million deal later today that will keep the Grand Final in Melbourne and held at the MCG until 2057, which undoubtedly ruffled some feathers and left non-Victorian teams disappointed.

โ€œThis is such a big event, one of the biggest events in the world, you need to be planning a year or two out,โ€ McLachlan told SEN.

The AFL boss conceded that logistics remain the biggest reason for locking the main event down in one location.

"You canโ€™t have the Grand Final going to the top ranked team because you need to know where youโ€™re playing the Grand Final from a long way out," McLachlan explained to SEN.

โ€œWe are committed to the MCG, itโ€™s been here for 100 years, it holds 100,000 people and we get the most amount of people coming to it and you feel itโ€™s the home of our Grand Final."

โ€œWe have gone for a model where we maximise the crowd."

McLachlan mentioned that his decision on a Grant Final reform to a twilight time slot will come later this month and is aware of the talks surrounding the best of three Grand Final series that some non-Victorian clubs are reportedly clamoring for.
