GREATER Western Sydney's new list manager Craig Cameron has called on the AFL to avoid tweaking its academy and father-son bidding system for at least another year.

The AFL sent a discussion paper to clubs earlier this month asking for their feedback on possible changes to the bidding system, including closing the 'loophole' that saw clubs trade early selections for more picks under the points-based process last year.

Northern academy clubs and others with access to father-son selections get a 20 per cent points discount if they match a bid during the live draft night system. 

But one proposal put forward by the AFL was that if a club did not keep a selection within 18 picks of a player bid in the first round then it would not receive the discount.

Feedback from clubs was due earlier this week on the possible tweaks and Cameron, who was appointed to the Giants job in May after previous roles in football at Melbourne and Richmond, said the club had encouraged the League to avoid implementing changes. 

"We understand there's some unintended consequences around the points system. I think one of the most contentious positions is the trading back of draft picks more so than the acquisition of players to some degree, and how that impacts the first round," Cameron told AFL.com.au's Road to the Draft podcast.

"I understand there's some consternation around that but it has only been one year and I'm sure they didn't come up with the system overnight. To throw it out in one year is not giving it a lot of time to settle.

"We made decisions strategically last year based on the rules as they were, and the clubs we traded with have actually benefited from those decisions."

He added that because clubs had traded future picks last year for the 2016 draft, the system should remain untouched. 

Cameron also defended the Giants' hold on its wide Riverina academy zone, which has been the subject of much anger from rival clubs.

Some industry figures, including Hawthorn list manager Graham Wright and Adelaide recruiting manager Hamish Ogilvie, have said the Giants should not get access to prospects who are in the Victorian TAC Cup system.

But Cameron said the club needed to continue to ward off rugby rivals in that region, saying the AFL's increased academy presence had shown results in recent drafts.

"We can't think that those other codes aren't going to get their act together at some point," he said. 

"We're producing more players than have been produced, and I think if we continue to go the way we are and add a few other elements to it then we'll win the war. But the other codes will probably, at some point, decide they have to fight back a bit."

The AFL has not ruled out realigning the Giants' zone and Cameron has met with League officials to discuss their plans with the northern academies. 

"I've got the sense that they're still considering all sorts of things, to be honest," Cameron said.

"There's a number of things that haven't been in place for long enough for them to have enough data to make decisions at this stage. So I think they're considering a lot of different things."

The Giants have a number of likely academy prospects again this year, including midfielders Will Setterfield, Harry Perryman and Kobe Mutch, and key defender Harrison Macreadie.
