TOHGA | The Old Hills Grammarians Association

Welcome to The Old Hills Grammarian Association (TOHGA). This platform is dedicated to celebrating and connecting with our extensive alumni community.

Here, you'll find access to a rich network of former students who have journeyed through Hills Grammar, creating meaningful bonds and achieving remarkable accomplishments.

We enjoy connecting with former students in a variety of ways. Please contact tohga@hillsgrammar.nsw.edu.au with any questions.

Introduced in 2015, the Hills Original Alumni Award celebrates the achievements of our Graduates. It is presented each year to a 'Hills' alumnus who embodies our motto Strive for Excellence. 

Recipients are leaders in their field and embody the School values of Respect, Integrity, Service and Excellence.  It recognises a 'Hills' alumnus who has gone on to achieve extraordinary personal and professional success in their field of endeavour.

We encourage our past students, parents and community members to nominate a Hills Grammarian for the Hills Original Award. The online nomination form is accessible here.

To enhance our curriculum and provide a “real world” perspective for our Hills Originals, our teachers are always keen to draw on the expertise of our broader school community.

As part of building our knowledge of the various and wonderful paths our Hills Originals have taken since leaving our gates, we want to learn more about your interests. Are you a tech specialist, a creative artist, a medical expert, a business enthusiast, or perhaps an environmental advocate? We’re excited to know which field or fields spark your curiosity or capture your expertise.

Your insights and experience will help us provide a rich and expansive resource to our students to complement the curriculum.

Thank you for your time and we look forward to learning more about the Hills Grammar Alumni community.


Each year we invite specific ‘milestone’ year groups to a reunion at School or off-site.  

These events serve as an opportunity to reminisce, catch up on each other's lives, and reinforce connections.  

Come relive those treasured moments and celebrate the journey since then, reconnect with old friends, and make new memories.
