Cahill has put his own money behind a bid to get a Wollongong-based franchise, South Coast FC, into the A-League and hopes to contribute to the club on the field as well.
''For me it's all about the kids and producing a pathway for them to live their dreams in a competition that is improving all the time,'' Cahill said.
''Nothing would give me greater pleasure than to round off my football life playing for a team that I'm convinced will get a licence to join the competition sooner rather than later.
''The fact I can be part of the club's player development in terms of giving kids in the region a chance to excel would only make it sweeter. I'm in this project for the long haul.
''I want to be part of the club in meaningful way on the field too. I want to come home when I still have something left to give as a player. That's also very important to me.
''Obviously I couldn't be happier where I am right now at Everton, but it would great to be a part of helping build the game up back home too because football has given me a great life.''
