The Illawarra Premier League is a regional Australian semi-professional association football league, comprising teams from the Illawarra, and South Coast regions of New South Wales. The competition is run under the Football South Coast body, an associate of Football NSW - a member federation of Football Federation Australia. It therefore fits below the national A-League and NSW wide divisions including National Premier Leagues NSW, making it a level 6 league in the Australian League System. The major sponsor for the Illawarra Premier League is the Illawarra Mercury and as such the competition is often referred to as the Illawarra Mercury Premier League.
