The Old Boys’ Association has played an integral role in the history and tradition of Toowoomba Grammar School. It was formed on December 29, 1888, when 25 Toowoomba Grammar School Old Boys met at Long’s Imperial Hotel to create a new society. The Toowoomba Grammar School Old Boys’ Association rules were drawn up, and office-bearers elected. The inaugural president was Mr Joesph Vincent Herbert Esq. (TGS 1877-80)

From there, the TGSOBA has grown significantly, ensuring that the Blue and Gold network and connections continue beyond the School gates. They guarantee that the special bond of the TGS boys is never lost and that School traditions are honoured from generation to generation.

The TGSOBA contributions are numerous and varied, and while there are too many to mention, here is a list of some notable projects:

Not only is there the infrastructure, but Old Boys contribute to the lives of our current students in many ways — from coaching sporting groups, assisting with performing arts or other subjects, providing mentorship, offering work experience, returning to the School to share their stories and experiences and volunteering at various events, including in the canteen on sports days.

There are so many ways that our Old Boys have a presence here, and the TGS community is grateful for their support. We hope that this leadership and the spirit of the Blue and Gold continues and that future generations of Grammar boys enthusiastically follow in the footsteps of their “ancestors”. We hope that these boys remember where they came from and the opportunities available to them because they were fortunate enough to be a Grammar boy, to be part of an inexplicable band of brothers. We hope they are eager to return to these glorious grounds, give back and set a fine example of what it is to be a good man. Fidelis in Omnibus.
