 Lutheran leaders in South Australia recognised that the College was too important to the future of the church for it to remain in a remote country town in Victoria, so Concordia moved to its present Highgate site in 1905.Due largely to the efforts of Pastor P. B. Zweck, Concordia became a Christian co-educational secondary college in 1927, operating under the South Australian District Synod of the Lutheran Church of Australia.Today the College caters not only for Lutheran families, but for all students whose parents are prepared to support the educational program and Christian ethos.
