The East Coast Superleague is New South Wales senior contact competition and is run under the direction of a committee of the New South Wales Ice Hockey. An amalgam of the former Junior and Senior A divisions the league was created to bridge the gap between junior hockey and the national leagues, providing an avenue for those players seeking to make the move into the national leagues but also giving those who wish to play competitive contact hockey the opportunity.

With this emphasis on development, the league is primarily a 23yrs and under age division but seeking to expose players to a better standard and maturity of play each team can include, up to, 5 overage players.

To maximize competitiveness the Sydney based league teams are based on a draft system keeping the teams, within the league, to a balance ensuring close competitive hockey.

The East Coast Superleague plays a 21 game season with 2 game semi final series and a 3 game final series, the only Australian league to play a multi game post season, and drawn regular time play off games are determined by over time not penalty shoot outs, another rarity in Australian hockey.

Although Sydney based, 2005 saw the Newcastle Northstars enter the ECSL placing their national league farm team into the competition.

2006 sees the ECSL enter its 5th season looking to build further on the success already achieved and further fulfill its primary aim of improving the quality of New South Wales and Australian ice hockey.
