The Trinity Community

The Trinity Community

Trinity has a very proud history of philanthropic support from its parents, Old Boys and Friends of the School. The School’s many completed projects and works would have not been possible except for the incredible generosity and selfless sacrifices made by the many generations of Trinity’s families. Your donations, however big or small, provide the boys of Trinity today with the facilities of tomorrow and we truly appreciate your generosity.

Continuing your financial support across other Trinity Grammar School projects will help the boys realise their potential, passions and purpose for many more years to come.

Society of the Arts

“The School is immensely proud of its Society, which has had a continuous existence since its foundation in 1951. It is dedicated to helping its students, their families, staff and other like-minded people in the wider community, enjoy and gain a greater appreciation of the visual arts, music and drama. The 2015 programme for the Society was wide-ranging and included concerts and exhibitions as seen here with violinist Janusz Wawrowski. Membership is open to all and this year includes admission to six exceptional concerts, an evening of short-form performance and invitations to previews of five curated exhibitions.”

Annual Giving Appeal

Parents' & Friends' Association

The role of the Parents’ and Friends’ Association is:

  • To provide a forum through which parents and friends of Trinity can interact positively with the School;
  • To encourage a greater spirit of community and service;
  • To secure additional amenities for all the boys of Trinity to enjoy and to help them achieve their full potential.

This Association was started in 1928 and has provided the School with many facilities that benefit the boys of the School. Some of the outstanding assets are Compass Court, the organ in The Roderick West School of Music, the multimedia and air-conditioning in The James Wilson Hogg Assembly Hall, and the bus shelter on Chapel Way.

Support Groups

Auxiliary groups of the Parents’ and Friends’ Association are the Summer Hill, Strathfield and Junior School Auxiliaries. All Auxiliaries work tirelessly in the interests of the School across areas such as the canteens and clothing pools. The Auxiliary groups are an organisation of willing volunteers always on the lookout for new members and new helpers. The Auxiliary organises various social activities throughout the year to provide opportunities for Trinity parents to build relationships and friendships and thereby strengthen the School community.
