Trade-offs
- !Girls-only — excludes families seeking co-education
- !Anglican faith heritage may not suit secular or other-faith families (a fit consideration, not a quality flag)
- !High fees typical of elite Sydney independents (exact figures not public in the sources reviewed)
- !No verified IB Diploma pathway — families wanting IB must look elsewhere
- !Public enrolment data is inconsistent across sources; precise current size unverified
- !No boarding — non-Sydney or overseas families must arrange their own accommodation
- !Total enrolment and class-size data are not publicly published, reducing independent transparency
- !Vertical CBD campus means limited on-site green/playing-field space versus suburban peers
- !IB Diploma carries an extra fee surcharge on top of already-high city tuition; overseas fees plus a AUD 10,000 bond are steep
- !No early-years/preschool and no PYP — entry starts at Kindergarten, so no IB continuum for younger children
