AFL boss Gillon McLachlan has ruled out segregating rival fans in the wake of a post-match brawl between Melbourne and Geelong supporters.
Membership and lifetime bans are on the cards for those found to have been involved in the fight after the final siren at Geelong's GMHBA Stadium on Saturday night.
It sparked calls for the AFL to take drastic action but McLachlan ruled out separating fans. He also raised the possibility of a game security review.
"It's core to us that you go with mates from the opposition team, you sit side-by-side with people from the opposition supporter groups," McLachlan told 3AW radio on Monday.
"By and large they get on incredibly well - it's part of the banter and the fun."
A man who recognised himself in social media footage of the brawl is voluntarily assisting police.
"His involvement in the incident is still to be determined and the investigation remains ongoing," a spokesman told AAP.
Speaking about those found to have been involved in the incident, McLachlan said "whether it's strip memberships, whether it's police prosecute them for assault, that will play out in coming days".
The AFL's general manager of clubs, Travis Auld, told reporters the code wasn't going to let a small number of wrong-doers ruin games for well-behaved fans.
"We have almost seven million supporters attend our games each year and there's a few of those, a couple, a very small number that are trying t ruin it for everyone else and the answer is those people need to be held accountable," he said.
Saturday's brawl was the latest of several incidents of fan unrest at AFL games this season.
The Cats are reviewing the incident to determine if any action needs to be taken by the club.
"Football is an inclusive sport and every supporter that attends a game should be able to do so in a safe and enjoyable environment," Geelong said in a statement.
Melbourne Football Club chairman Glen Bartlett labelled the behaviour unacceptable.
