Football Federation Australia bids to clamp down on the transfer of minors to overseas clubs.
The crackdown is to protect the interest of players and also the development of youngsters in Australia.
FFA CEO Ben Buckley said it was now time to take more notice of the country's young, developing stars.
"It's definitely a tougher line, and we make no apologies for that," Buckley said.
"The rules of FIFA are quite clear, and in many ways we are simply making sure we enforce them more rigorously. But fundamentally, this is about trying to make sure players are not misled, at the same time as protecting our own development programs.
"We've now got an improved development pathway, we've got the National Youth League, and of course we've got the A-League. There's less and less reasons for a player to go overseas at a young age. That's the message we want to get across."
