Grammar 150

Celebrating Toowoomba Grammar School’s 150^th anniversary.

In 2025, Toowoomba Grammar School celebrated its sesquicentenary or 150th anniversary. It was referred to as Grammar 150 and was an incredible year for the School.

Created by the community for the community in 1875, TGS was founded to ensure that families have access to a high quality, holistic education for their sons within a welcoming environment that understands their needs.

Since the laying of the foundation stone on 5 August 1875 by Justice Lilley, the School has sought to grow and build our students to succeed - to succeed in their chosen careers, to succeed as sons, partners and parents and to succeed as leaders in their community and beyond.

Celebrating Grammar 150

TGS has a community like nowhere else

Financial contributions of local graziers, businessmen and townspeople, matched by a donation from the Queensland Government enabled the creation of Toowoomba Grammar School.

Thanks to the vision of our first Headmaster, John Mackintosh, TGS has long had a focus on character development and that remains central to all that we do today. As one of Australia’s largest boys’ boarding schools, boys from all around Australia and the world have called TGS home over the last 150 years.
