OSU Members

All past students of Sydney Grammar School are eligible for membership of the Old Sydneians’ Union and we are pleased to note that over the years, almost everyone who is eligible has chosen to become a member of the Union. Current eligible membership is approximately 13,737, yet we only have email addresses for 5,802 members. So … we need your contact details, you can be as brief or as expansive as you care to be.

Fill in the form on the Registration page and an email will auto forward to the OSU Office for verification and a return email confirming your online membership will be sent to your email address. You are then able to login to the OSU Online Mentoring site either as Mentor or as prospective Mentee.

The OSU Privacy Policy is published on the website.
