Through community events and philanthropic support, the Trinity community works
together to create a wonderful environment for future generations
of Trinity students.

Close-knit and diverse, the Trinity community is committed to supporting boys as they
grow in mind, body, and spirit. Many of the School’s completed projects and works
would not have been possible except for the incredible generosity of the Trinity
community past and present

Trinity Community Groups

Trinity Alumni

All alumni are automatically members of the School’s Old Trinitarian Union (OTU). Visit our Alumni page for more information.


Trinity Connection

The Trinity Connection originally formed in 1989. Started by a group of mothers who wished to stay ‘connected’ after their sons had left the School, the Trinity Connection has since expanded and includes all past parents and carers of boys who attended Trinity.


Parents’ & Friends’ Association

The Trinity Parents’ and Friends’ Association started in 1928 and has a long history of providing great resources for the School and engaging in important conversations surrounding the future of the School. Some outstanding facilities the Association has secured for the School include: 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 and additional classrooms at our Field Studies Centre in Woollamia.


P&F Meetings

During term, Parents & Friends hold evening and afternoon events to give parents and caregivers a forum to find out more about the School and take the opportunity to ask questions of the Head Master and other senior staff.

Please see the School diary for the next meeting.
