All of this talk about Youth playing in the A-League this season, and just a general interest in youth development, got me thinking. 

Which clubs both A-League/NSL/NPL Have the best youth academies/teams?
Take into account amount of Socceroos/olyroos/joeys each academy has produced, or the most successful teams in each youth/NPL competitions.

Most notably, Sydney FC and Adelaide United recently have shown that their academies have been successful in different ways, But the majority of these kids start somewhere else.

Clubs like Manly United, Sydney United, Blacktown City, Croydon Kings, Adelaide City, Avondale FC, South Melbourne, ECU Joondalup, Western Pride, Lions FC, for me stand-out as seriously good clubs either in the past or currently as breeding grounds for top talent, I'm interested to hear what others think. 

I'm a relatively new football fan in the whole scheme of things, so don't know too much about the NSL days of youth development, but feel that that same culture and recipe is still there for some of these clubs.
