About Collegiate Old Girls' Association


Reflect   Revisit   Rediscover   Rekindle   Relive   Reunite

Formed in 1927, COGA was established to foster a sense of community among Collegiate’s former students and to assist them to maintain life-long contact with each other and with the School.

Over our century and a quarter history many thousands of girls have been through our doors. As a School, we are very proud of their ideas, passion and achievements. They have followed a great variety of paths in their lives and they are people who have helped shape the communities in which they now live. They are Olympians, Rhodes Scholars, familiar faces on TV and scientists making ground-breaking advances. They are nurses and teachers, mothers and carers.  We celebrate them for making a difference and for inspiring future generations to do the same.

Tremayne Club

The Tremayne Club is a very special group of Old Girls who left Collegiate fifty or more years ago.

Meeting regularly throughout the year, the Tremayne Club gives members the opportunity to catch up with old school friends in welcoming, comfortable and cheerful surroundings. Members of the Tremayne Club are invited to Collegiate throughout the year for a series of special activities such as meetings with the Principal, luncheons and special St Michael’s and Founders' Day celebrations. The Tremayne Club is also involved in important school events and celebrations.

The leader of the Tremayne Club is Mrs Diane Palmer (Gordon, 1955), assisted by Mrs Rosanne McDougall (Morrisby, 1953).

The Tremayne Collection

The Tremayne Collection is a gift to the School from the Tremayne Club. Each year, an artwork created by a Year 11 or 12 student is selected. The artist receives the Tremayne Prize at Speech Night and, in turn, the work is given to the School where it is hung or placed for all to appreciate.

The Tremayne Collection is now available to view online. Phase 1 of this collection features works from 2000 to 2017. Phase 2, showcasing artworks from 1987 to 1999, will be available shortly.
