Southern Districts president Andy Favaloro said their new agreement with A-League newcomers Macarthur FC will only grow the game and increase the number of "elite players" produced in the region.
The Bulls have committed to working closely and collaboratively with Southern Districts, Macarthur and Bankstown Amateur Football Associations who collectively represent more than 90 clubs and 28,000 players.
Executive Chairman Rabieh Krayem said over the next six months representatives from Macarthur FC will work productively with the three associations.
"We want to discover how we can invest in the game so benefits are felt right across the board. As an A-League club, of course we will support the local associations and clubs with coach mentoring programs, but this agreement is much more than that," he said.
"It's about consulting and working together in partnership to create new aspirational pathways and opportunities, along with tackling issues such as the cost of playing in the NPL.
"Working together will only make us stronger and more cohesive."
The agreement provides a pathway for the more than 10,000 registers players across 35 clubs in Southern Districts.
Favaloro said the association, which was formed in 1946, is a "hotbed" of football talent, producing countless Socceroos and Matildas.
"To now have a A-League club to collaborate with means players can continue their development close to home," he said.
Macarthur FC Deputy Chairman Gino Marra said: "This agreement is an important step for the future growth of the game. We know collaboration, consultation and engagement are the key components of successful stakeholder relationships and we're thrilled that such a unifying move has taken place at this early stage of our club's journey."
