Trinity College Gawler River
Trinity College began in 1984, when a small group of Gawler families opened a school with 27 students in the hall of St George’s Anglican Church, Gawler. The next year it moved to Alexander Avenue at Evanston South, and it has since grown into one college of six schools in Adelaide’s north, from preschool to Year 12, open to all families in a liberal Anglican tradition under the motto-like aim ‘excellence for all’.
