International Grammar School vs Redlands
🇦🇺 Sydney · Side-by-side comparison on verifiable public data.
Which should you choose?
Both run National, so the difference is inspection rating, boarding, and fees rather than the curriculum itself. The choice comes down to target curriculum, whether you need boarding, and budget — verify fees against each school's own figures.
Neither International Grammar School nor Redlands sits in a market with a public inspectorate, so both are assessed on verifiable accreditation, curriculum authorisation, and published data rather than an official quality rating.

- ✓Secular and co-educational — a deliberate non-denominational alternative
- ✓Inner-city Ultimo location moments from Sydney CBD; Preschool–Year 12 continuity

- ✓Co-educational K–12 continuity on a single Lower North Shore campus from Preschool to Year 12
- ✓Strong school-reported senior outcomes (top IB ATAR 99.95; 247 top-band results in 2025)

Trade-offs
- !Does NOT offer the IB Diploma despite the 'International' name — senior pathway is HSC only (verified across the official site)
- !No current public enrolment figure verifiable (most recent data is ~1,100–1,200 from 2007 via Wikipedia)
- !Published fees not extractable — only downloadable 2026 PDF schedules; overseas-student fees 'available upon request'
- !EAL/EALD support not stated on public pages (cannot confirm)
- !Inner-city site implies limited green/sporting space versus suburban grammar schools
- !Day school only — no boarding, so families relocating without a resident parent cannot easily place a child here
- !High fees (≈AUD 47,100/yr senior years) plus extras; the IB pathway carries a further AUD 2,950/yr surcharge
- !Total enrolment is not published on the school site, limiting transparency on school size
- !Publishes HSC and IB results combined and discloses no standalone IB Diploma average points score
- !IB is confined to the Diploma (Years 11–12) — no PYP or MYP, so the IB experience doesn't run through the junior/middle years
