Upcoming Events

The OSU aims to encourage and facilitate ongoing interaction between the Alumni of Sydney Grammar School and to also assist the School. In conjunction with the School we support year group reunions to meet at least every five years.

Membership – All Old Sydneians are automatically members of the OSU. However, we do ask that new leavers register and become financial members for a one-time payment of $275 to provide funds to support the efforts of the OSU and our support for the School. You can become a financial member via the following link – OSU Financial Membership

Creating your account also enables the OSU to keep you informed of our activities, such as the new Mentor Program. Register Now

Mentor Program – We are excited to announce the OSU Online Mentoring Program. Read more about the program

Old Sydneian of the Year – Calling for nominations for the 2021 Old Sydneian of the Year. Read more and nominate a candidate
