Our community is central to who we are. Celebrating and strengthening the relationships across our student, staff, families, alumni and philanthropy networks reinforces what makes Trinity, ‘Trinity’.

When your child joins Trinity Grammar School, you and your family become part of a vibrant, inclusive and welcoming community. A community for which Trinity is well-known.

Throughout your child’s journey at Trinity, there are myriad opportunities for you to engage with other parents and guardians, make new friends, share your skillset with others and simply enjoy being a part of the various activities and festivities.

Ranging from attending a spectacular event, volunteering on a parent committee or as a Year Level Class Representative, there is something to suit everyone.

Parents’ Association

The Trinity Grammar School Parents’ Association’s (PA) primary objective is to support the school’s initiatives, plan events and facilitate engagement within our parent and guardian community.

Friendraising and fundraising forms part of the annual activities and any funds raised are used to support the students and the school.

The PA Committee is the umbrella organisation for the many sub-committees which support special interest, cocurricular and key community events, giving parent and guardians a diverse range of ways to volunteer.
