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.

Annual Dinner 2019 – Bookings now open for this year’s dinner. Saturday 21 September, join us for pre-dinner drinks & dinner in Big School commencing at 6.30 pm for dinner at 7pm. Dr Rowan Gillies (Senior Prefect SGS 1988) has accepted our invitation as Guest Speaker. Rowan is a highly respected plastic surgeon at Royal North Shore Hospital and is the youngest ever International Council President of the Nobel-Prize-winning Médecins san Frontières and has worked in some of the world’s most troubled regions. He is currently part of the Lancet Commission on Global Surgery.

On the evening we will also announce the “Old Sydneian of the Year 2019”.
