Old Knox Grammarians' Association


The Old Knox Grammarians' Association (OKGA) is a group of over 15,000 registered members, all of whom share the common experience of having attended Knox.

The association is very diverse, with members who attended the school when it first opened in 1924 through to those who graduated last year. We now have families with four generations of Old Boys. Our members include business leaders, Supreme Court Judges, politicians, academics, Rhodes Scholars, military leaders, high profile people in the media, arts and entertainment, diplomats, community leaders, Olympians and Paralympians, Wallabies players and adventurers.

The OKGA is all about staying in touch with those who share common experiences, values and connections. Our recent focus has been on assisting members with networking, mentoring and financial advice. OKGA members also receive a weekly eNews bulletin with news of Old Boys and the School.


Membership of the OKGA is for life and requires the payment of a one-off fee (currently $500).

To join the OKGA, please contact the OKGA Office.
