Making a difference, everywhere.

As a school of choice for generations of the Colac-Otway community, Trinity College has deep ties to many families and businesses in the area, and beyond.

Our past students have gone on to thrive on the world stage, showing the difference of a Trinity education in everything they do, and we also have many alumni who have remained closer to home, providing incredible service, support and passion so essential to every aspect of a thriving community.

Visting the College and Reunions

We welcome our past students back to their College any time and love to hear their stories of life beyond graduation.

We will be holding a reunion for all years on Saturday 23 November at 6pm at Trinity College. Tickets will be available closer to the date – follow our Trinity College Alumni Facebook page to keep up to date!

Share your story

Many of our former students have gone on to make a difference and we are so proud to be part of their story. We are always looking for alumni to share their adventures and achievements and would love to celebrate what has been happening in your life.

We would welcome any information that people would like to share for future newsletters with a few paragraphs on where your journey has taken you since you left the College and where you are now. Alternatively, you might like to write just about a special memory you have of your time at Trinity College or St Joseph’s College.

Any input will be appreciated and can be sent to
