St Columba College

St Columba College is a Catholic and Anglican co-educational school located in Andrews Farm, a northern suburb of Adelaide, South Australia. The college has two campuses — Primary and Secondary — on both sides of President Avenue, the main street of Andrews Farm, and enrols approximately 1,600 students across Foundation to Year 12.

St Columba College was the first joint Catholic and Anglican co-educational school established in Australia. It was founded in 1996 (with first students enrolling in 1997) as an ecumenical initiative by Ian George and Leonard Faulkner, the Anglican and Catholic Archbishops of Adelaide at the time.

The college offers a broad Student Life program giving all students access to a wide range of sports, clubs and co-curricular groups. Dedicated wellbeing programs are embedded across both campuses, designed to support students academically, socially and emotionally throughout their schooling journey. The college's approach to wellbeing is underpinned by Positive Education principles, with a focus on resilience, belonging and individual student growth.

St Columba College has undertaken a significant infrastructure investment across its Secondary campus to support growing enrolment demand. In 2024, the college formally opened the first of two new Secondary buildings as part of a $20 million expansion.^[6] The new building includes 12 new classrooms, outdoor learning areas, a Wellbeing Hub and a dedicated Diverse Learning Centre. Existing Secondary facilities were also refurbished as part of the project, including covered sports courts and a dedicated Performing Arts Theatre.^[7] The opening was officially blessed by both Catholic Archbishop Patrick O'Regan and Anglican Archbishop Geoffrey Smith, alongside South Australian Education Minister Blair Boyer MP.

A second new Secondary building, the Clonard Building, is due to open in Term 2, 2026.^[8]

Redevelopment of the Primary campus is planned to commence at the end of 2026, with the expansion designed to accommodate the college's growing enrolment, which reached 1,600 students in 2026.

St Columba College has been recognised for providing quality independent education to families across Adelaide's northern suburbs. In February 2026, the college was featured in The Advertiser in a report examining data published by the Australian Curriculum, Assessment and Reporting Authority (ACARA), which showed that South Australian independent schools charge the lowest average fees of any state in Australia.^[9] The article featured a St Columba College family as an example of the value and quality of care that South Australian independent schooling delivers, with the college recognised for its strong pastoral support programs alongside its accessible fee structure.
