Trinity Grammar School is a community. This is the case not just for those who gather onsite today, but also for the thousands of boys, parents and staff who have been part of the School’s story in the years and decades gone by. Whilst this extended community is scattered across Sydney, Australia and the globe, and whilst it is diverse in age, life experiences, and vocations, the connections that constitute this community are invaluable. Some connections arise from sharing the formative years at the School and some have emerged in subsequent years. Some connections have been incidental and others intentional. Some connections are very strong and others are less so.
The intention of this site is to enable and to strengthen the connections between alumni, and between alumni and the School. We hope and pray that these connections will benefit individual alumni, the extended School community and the wider world in which we live and serve.

Trinity acknowledges that social stigma and silence around male sexual abuse and assault result in a lack of awareness and understanding about the effects of these experiences, and what men need to move forward.
The School has channels available should any former student wish to report abuse experienced at Trinity. Any disclosures will be directed to the Headmaster and treated confidentially and sensitively. Click here to access a confidential channel for any alumni seeking to report historical abuse, plus a list of resources, including 24/7 crisis lines and access to peer-support.
