"We played six quarters with 30 players [at Arden St], teams of 10, seven on the ground – that's just a new form of the game we are looking at for international and here, for exhibition games," he said.

"That's progressing now. We will review the vision and the GPS of that trial and keep developing it. But it's certainly on our radar to develop that game properly and put it on somewhere."

Given the initial title of AFL X, the concept could even be aimed more at just-retired AFL players, for the required level of fitness could be as great as traditional football. The GPS results of some Kangaroos players were understood to be greater than in a normal game.

"We are looking to put on an exhibition game at least – the guys are working pretty hard on that," Lethlean said.

"It's a great fun, fast form of the game that we think might have some legs in varying forms, for past and present players, maybe an exhibition game, maybe in the week off here to have an exhibition game. Something different might be good."
