AFL chief executive Andrew Demetriou has conceded it may be time for the league's commission to review cost-of-living allowances outside the salary cap.
In the aftermath of Sydney winning this year's premiership and then looking to recruit Adelaide forward Kurt Tippett, the allowance from the AFL to Sydney clubs to combat players' greater cost-of-living expenses in the harbour city has been criticised.
Both Sydney and GWS are allowed approximately $900,000 more under their salary cap but Demetriou revealed the AFL commission is keen to review it, although he denied it was a 'knee-jerk' reaction to the Swans' attempted recruitment of Tippett.
"I don't think we should make a knee-jerk reaction to the fact that Sydney Swans won a premiership based on their cost-of-living (allowance)," Demetriou said on Tuesday.
"Having said that, it was discussed at the commission yesterday and the commission ... we went back and we've looked at the last time we reviewed this was five years ago and maybe it is appropriate that we collate more information.
"You know, all the (Australian) Bureau of Statistics information, get some experts involved, some third parties and we'll get some more information and bring it back to the commission to have a look at."
Speaking at the AFL's announcement regarding new rules and interpretations for the 2013 season, Demetriou slammed public and media claims that the commission should leave the game alone and avoid rule changes.
While Demetriou and AFL football operations manager Adrian Anderson revealed a cap on interchanges would not be introduced next season, the AFL commission have agreed to the idea in principal, effectively paving the way for a restriction to 90 changes per game.
"We don't apologise for making changes," Demetriou said.
"This nonsense that you should put a moratorium on rules for five years and revisit them - if that was the case we wouldn't have a 3-1 (interchange) rule.
"We wouldn't have a much fairer competition ... if that was the case you wouldn't have a ruck rule where the centre circle's shorter and we'd have no ruckmen playing cause they'd all be out of the game with posterior cruciate ligament (injuries) ... of course you look at your rules.
"Moratoriums and time things are garbage."
Demetriou also hit back at claims from Collingwood president Eddie McGuire that a cap on interchanges would lead to players taking EPO, which has notoriously been used by professional road cyclists.
"You know I love Eddie dearly but I thought when I heard those comments he was on something," Demetriou said.
"I'm not sure what he meant by that, it doesn't make any sense to me. There's no correlation."
