How many IB schools in Greater Sydney
Greater Sydney has 22 schools currently authorised as IB World Schools across the metropolitan region. The cluster spans Sydney CBD, the Eastern Suburbs, the Lower North Shore, the Inner West and Macarthur, with a smaller presence in the Hills and Sutherland. About 12 of those 22 deliver the full IB Diploma Programme. The remainder offer the Primary Years Programme or Middle Years Programme only, with senior students transitioning to the New South Wales Higher School Certificate (HSC) for Year 11 and 12. Two further candidate schools are working through authorisation, both in the Inner West.
This dual pathway is uniquely Australian. Sydney IB families have a real choice between the IB Diploma and the HSC at the same school, and many of the leading independents now run both senior pathways in parallel. That makes school choice less binary than in Dubai or Singapore, where IB families effectively commit to the IB system. Compare options on our compare tool before shortlisting.
Fees and the three tiers
IB tuition in Sydney groups into three rough tiers in AUD. The value tier (AUD 25,000 to 30,000) covers schools such as International Grammar School (Ultimo) and St Andrew's Cathedral School (CBD) in primary years. The mid tier (AUD 30,000 to 38,000) captures most established names including Newington College, Wenona, Pymble Ladies' College PYP and Trinity Grammar. The premium tier (AUD 38,000 to 45,000) is the Diploma at Kambala, Ascham, the Diploma stream at SCEGGS Darlinghurst and the Diploma at SHORE. Capital levies, building fund contributions and IB exam fees add 10 to 20 percent. International student fees apply on top for non-resident families.
Published tuition is not the all-in number. Sydney independents layer on building funds (often AUD 1,500 to 4,000 a year), enrolment levies, technology charges and excursion fees. The IB Diploma exam series runs about AUD 1,800 per candidate in 2026. Our Sydney fees guide breaks the loading out by year group, including international student fee comparison.
Diploma versus HSC: which to choose
The Diploma versus HSC decision is the most consequential choice in Sydney IB schooling. The IB Diploma suits students likely to study at international universities, students with strong second-language options and students who want a broader subject load (six subjects from six groups plus the core). The HSC suits students with strong NSW-specific subject interests (English Advanced, Extension Mathematics, the various Society and Culture electives) and students aiming for the most competitive NSW university paths. Both convert into ATAR scores for Australian university entry; an IB Diploma of 38 broadly maps to an ATAR around 98 to 99.
For internationally mobile families, the Diploma is the default because it travels better. Families settling permanently in NSW often pick HSC because the cohort is larger, the teacher pool deeper and the university entry process simpler. Several Sydney independents allow students to switch from one pathway to the other at the end of Year 10, which is a useful safety net. See the IB curriculum hub for global context.

Illustrative example schools
The four schools below are illustrative, not a ranking. Each has been delivering the IB for at least eight years and reports Diploma results above the global average.
Kambala in Rose Bay runs IB PYP through Junior School and Diploma in Year 11 and 12 alongside the HSC. Eastern Suburbs heritage school with strong international university placement; small Diploma cohorts.
St Andrew's Cathedral School in the Sydney CBD runs IB PYP and offers IB Diploma alongside HSC at senior. Co-educational and centrally located, often the first choice for international families based in the CBD or Inner West.
Newington College in Stanmore is a long-established boys' school running Diploma alongside HSC. Strong cohort sizes for both senior pathways and a settled IB programme since the early 2000s.
International Grammar School in Ultimo runs IB PYP and MYP, with HSC at senior. Co-educational, deliberately multicultural and bilingual at junior level, a popular choice for relocating diplomatic and academic families.
Where IB families live in Sydney
Sydney's IB cluster splits into four geographic groups. The Eastern Suburbs (Rose Bay, Vaucluse, Bondi Junction, Edgecliff) covers Kambala, Ascham, Cranbrook and SCEGGS, and attracts the densest cluster of relocating international families. The Inner West (Ultimo, Glebe, Stanmore, Newtown) covers International Grammar, Newington College, Trinity Grammar and St Andrew's. The Lower North Shore (Mosman, Cremorne, Lane Cove, Crows Nest) covers SHORE, Wenona, Loreto and the leading PYP primaries. The Hills and Macarthur belt covers the leading IB primaries in newer estates.
Most international families settling in Sydney choose the Eastern Suburbs or Lower North Shore because of harbour proximity, established expat communities and the density of IB options. Inner West families tend to be longer-term residents or academic families based around UTS, USYD and UNSW. Commute matters: Sydney traffic makes cross-harbour school commutes painful and the school choice usually dictates the suburb, not the other way round.
Admissions calendar
The NSW academic year runs late January to mid-December. Most Sydney IB schools open admissions for the following January intake in March or April, with main offer rounds in August and September. Tier 1 schools close their main waiting list for Year 7 and Year 11 by August. Late applicants are placed on a waiting list and offered places as withdrawals come through, typically October to December.
For families targeting a Tier 1 school, apply 12 to 18 months before the desired start because many leading Sydney independents take registrations from birth and weight applications heavily towards sibling and alumni connections. For Diploma transfers, schools require the previous school's most recent report card, predicted IGCSE or MYP grades and an academic reference. Most schools assess in English and mathematics before offering a place. International student fees apply on top for non-resident families.
Frequently asked questions
How many IB schools are there in Sydney?
Sydney has 22 authorised IB World Schools across the Greater Sydney metropolitan region as of 2026. About 12 offer the IB Diploma Programme as the senior pathway, with the remainder running PYP or MYP only and transitioning students to the New South Wales HSC for Year 11 and 12.
How much do IB schools in Sydney cost?
IB Diploma tuition in Sydney runs from AUD 25,000 at lower-tier independent schools to AUD 45,000 at the established Eastern Suburbs and North Shore Diploma schools. Capital levies, building fund contributions, IB exam fees and transport add 10 to 20 percent. Add international student fee loading for non-resident families.
Is the IB Diploma or HSC better for Australian universities?
Both are recognised by Australian universities through ATAR conversion. The IB Diploma is typically converted to an ATAR-equivalent score; a Diploma of 38 maps to roughly an ATAR of 98 to 99. The HSC tends to favour students who do well in NSW-specific subjects, while the Diploma favours students with strong second-language and global subject options.
Which Sydney suburbs have the most IB schools?
The Eastern Suburbs (Rose Bay, Vaucluse, Bondi Junction), Inner West (Ultimo, Glebe, Stanmore) and Lower North Shore (Mosman, Cremorne, Lane Cove) hold the densest IB clusters. Macarthur and the Hills also have strong IB primary provision. Most international families settle in the Eastern Suburbs or Lower North Shore.
When do Sydney IB schools open admissions?
Sydney IB schools open admissions for the following January intake from March to June, with most Year 7 and Year 11 places filling by August. International families relocating mid-year can usually find primary places at PYP schools and Year 8 to 10 places at MYP schools; Year 11 and 12 Diploma transfers are difficult after January of the first year.
