SEISA boasts a rich legacy of sound leadership in the promotion and extension of sporting and cultural activities in an ever-widening sector of independent schools. It also provides Professional Learning and network opportunities for staff within the SEISA network.

SEISA aims to provide competition in a number of activities, across both Sporting and Cultural fields, to the students of Independent Schools in the South East of Melbourne and Gippsland. These activities are arranged in order to cultivate friendship, goodwill, co-operation, courtesy and healthy competition amongst the participating schools. Good sportsmanship and respectful competition is encouraged at all times. It was officially formed in 2012 featuring five independent Schools in the South East of Melbourne, and Gippsland. These Schools consisted of Beaconhills College (Berwick Campus), Beaconhills College (Pakenham Campus), Gippsland Grammar School, Newhaven College, St Paul’s Anglican Grammar School (Warragul Campus) and St. Paul’s Anglican Grammar School (Traralgon Campus).

The leadership of SEISA rotates every two years between member schools.

The 2024-25 SEISA Deputy Chair is Sam Watson from Beaconhills College, Berwick.
