Cranbrook School is an independent Anglican day and boarding school in Sydney’s eastern suburbs. It was founded in 1918 after a group of businessmen and church leaders purchased the Cranbrook estate with the aim of creating a major Anglican boys’ school. The school now operates across five campuses, including preschools, a junior school in Rose Bay, the senior school in Bellevue Hill and an outdoor education site in the Wolgan Valley. Enrolment is about 1,680 students from early learning to Year 12, including roughly eighty boarders.
Cranbrook plans to become fully co-educational by 2029, starting with girls entering Years 7 and 11 from 2026.
The school uses the International Baccalaureate framework in the junior and middle years and offers both the IB Diploma and the NSW HSC in Years 11 and 12. Cranbrook competes in the Combined Associated Schools competition and has won premierships in rugby, cricket, athletics, swimming, cross country, debating and several other sports.
The house system dates from 1931 and is central to student life, with twelve day houses and two boarding houses. Houses compete in sport and academic activities, and provide pastoral support across year groups.
Cranbrook has produced prominent alumni across business, arts, politics and sport. It is also one of the more controversial schools in Australia, facing public scrutiny over funding levels, governance disputes, cultural issues and several high profile media investigations.
