Geelong Grammar School

Geelong Grammar School (GGS) was established in 1855 under the Church of England and is today a private Anglican co-educational boarding and day school. Its principal Corio campus sits on Geelong's northern outskirts overlooking Corio Bay — roughly an hour from central Melbourne — not in central Melbourne itself. It is filed under Melbourne here as a greater-Melbourne / Victoria grouping; the senior and boarding heart of the school is at Corio near Geelong, with a separate day campus at Toorak in Melbourne. This location nuance matters for families assuming a city school.

The school operates four campuses: Bostock House (Corio area, ELC–Year 4, day); Toorak (Melbourne, formerly Glamorgan, ELC–Year 6, expanding to Year 7 in 2027); Corio Middle & Senior School (Years 5–8 and 10–12, day and boarding); and Timbertop, a full-time boarding campus for Year 9 in the Victorian High Country, established 1953. It caters for approximately 1,500 students Pre-school to Year 12, including around 800 boarders.

Academically, GGS has been an IB World School since 1997. The IB Primary Years Programme frames the early/junior curriculum (ages ~3–12), and in Years 11–12 students choose between the IB Diploma Programme and the VCE (plus a VCE Vocational Major pathway). For the Class of 2025 the school publicly reported a combined IB/VCE median ATAR of 83.30, a dux scoring a perfect IB 45 (ATAR 99.95), over 20% of IB students earning a perfect subject score of 7, and 98%+ receiving a first-round tertiary offer.

GGS is internationally known as a pioneer of Positive Education and runs its own Institute of Positive Education. Notable alumni include King Charles III (who attended Timbertop), Rupert Murdoch and Portia de Rossi. It is a member of AHISA and a founding member of the Associated Public Schools of Victoria. Australia has no graded national inspectorate, so the tier reflects accreditation + curriculum depth — capped at A.
