An extra round, so 23 rounds, the 1-6, 7-12, and 13-18 categories play each other twice. Double up interstate rival matches, plus two Victorian sides from different "zones" playing each other twice. I'd go with Tigers vs. Pies x2, Cats vs. Hawks x2, Saints vs. Dogs x2, and Blues vs. Dees x2.
Grand final would ideally be in the home state of whoever finishes 1st. Still, naturally, due to the MCG contract, it'll be there, unless Victoria has another wave at the wrong time, which is possible because a vaccine is unlikely until late 2021. By then, there'll be more open travel. If Victoria is unable to host it again, then go with Optus, and Adelaide Oval as a backup.
