- ✓Five second-language options plus a compulsory third language from Year 7; languages continuable to HSC level
- ✓Strong, publicly published HSC outcomes (top ATAR 98.75; ~30% of cohort ATAR ≥90 in 2024) including First-in-State language results
- ✓Secular and co-educational — a deliberate non-denominational alternative
- ✓Inner-city Ultimo location moments from Sydney CBD; Preschool–Year 12 continuity
- ✓Genuine dual senior pathway — students can choose the full IB Diploma or the HSC, a real choice rather than a token offering
- ✓Longest continuous IB provider in NSW (since 1988), signalling depth of institutional IB expertise
- ✓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
