Other codes do it. Why can't the AFL?
Which other codes?
In Australia the NRL is always set in a venue. A-league soccer is the only one that seems to have a variable Grand Final venue, but that's a much smaller league than the AFL and NRL and therefore easier to schedule at the last minute. Also AFL and NRL have obvious heartlands in Melbourne and Sydney, respectively. That's not the same with soccer.
And heck, even the Big Bash Cricket is moving to a fixed grand final venue in Canberra.
