Tasmania have been given the green light to join the AFL as the league's 19th team, leaving those in New South Wales hoping the AFL don't forget about player development up north.

Speaking during the week, Sydney coach John Longmire said the AFL still needed to "do work" in the state to ensure more people were playing the sport in what he labelled "the most competitive sporting market in the world".

"Let's not take our eye off what's happening here in NSW in the most competitive sporting market in the world," Longmire said.

"What we're mindful of is one third of Australia's population is in NSW, and yet only five per cent (of AFL players come from this state).

"We're all focused on Tasmania, which is terrific.

"But if you've got one third of the population sitting here in NSW and only five per cent playing AFL football, I think we need to do a bit of work in that space."

Those sentiments have been echoed by the Giants, who are seeking changes from the AFL.

Speaking on 3AW, Giants chief Dave Matthews said the club had inquired with the league about getting extra rookie spots on their list and scrapping the bidding system for players in Western Sydney.

"We've actually got a submission in with the AFL," Matthews said.

"I think we put it in for the last September where we talked about getting additional rookie spots and and looking to free up the bidding system particularly in Western Sydney.

"That doesn't doesn't worry me as much in other parts of New South Wales where you might have to bid on a player like Harry Himmelberg But in Western Sydney ultimately what we've got to try to think through is what's a compelling career opportunity for an elite athlete in Western Sydney?

"The bidding system is simply a blocker, like it's imposed and it's a decision made within the AFL that actually hold you back in terms of proposing a talent pathway when you've got a young athlete in Western Sydney says 'I've got Rugby League clubs all around me, I've got soccer all around me. It's a massive basketball market.'

"None of these sports are actually putting barriers in front of the young boy or girl in terms of what the career pathway is.

"So we've asked the AFL to consider getting rid of the bidding system in Western Sydney. And I think it makes sense because if we're able to stimulate that market more than we have, as you've said, every time we list a kid from Sydney, that's one kid from Melbourne or WA or South Australia or in this case Tasmania that goes to another club or gets spilled back into the pool."

The Giants currently have just two players from Western Sydney - Kieren Briggs and James Peatling - on their list.
