🇦🇺 International Schools in Sydney

8 schools, profiled on verifiable public data.

Sydney's school market is dominated by elite independent schools rather than international schools in the Asian sense — long-established, often single-sex and faith-affiliated, most teaching the academically rigorous NSW Higher School Certificate (HSC). A meaningful minority, however, also offer the IB Diploma as a senior alternative — Redlands has run it since 1988 (the longest in NSW), and St Andrew's Cathedral School and Newington College offer it too — so internationally-mobile families wanting a portable curriculum do have genuine options here. Australia has no single graded national inspectorate; quality is signalled instead by state registration (NESA), the transparent ACARA/MySchool dataset, and publicly reported HSC/ATAR results. Two things still matter for expat families: many top schools remain HSC-only (less curriculum-portable than IB), and some elite schools restrict enrolment to citizens/permanent residents. Fees are published in Australian dollars; boarding, where offered, is charged separately.
