Sydney is one of the most multicultural cities in the world, and that diversity is reflected in its schooling. Beyond the well-known Australian independent schools, the city is home to a strong network of bilingual and dual-language international schools serving French, German, Japanese, Chinese and other communities. For expat families relocating in 2026, these schools offer a way to maintain a second language while preparing children for either Australian or international university pathways.
This guide walks through the bilingual landscape in Sydney, the schools that consistently rank well, fee benchmarks, admissions and the practical considerations that matter when choosing between an Australian curriculum, an IB programme or a foreign national curriculum.
Bilingual schooling in Sydney: how it works
Three broad models exist:
- Foreign national curriculum schools follow the home country's syllabus (French Lycée, German International, Japanese, Chinese) and lead to baccalaureates or equivalents recognised internationally.
- IB World Schools integrate language acquisition into the IB framework, often with French, Mandarin, Japanese or German as a second language from primary onwards.
- Australian independent schools with strong language programmes offer the NSW HSC pathway with bilingual streams or accelerated language tracks for native and near-native speakers.
The right model depends on whether your family expects to remain in Australia long-term, return to a home country, or relocate again to a third country.
Top bilingual international schools in Sydney
The International French School of Sydney
IFSS follows the French national curriculum from Maternelle through Terminale, preparing students for the French Baccalaureate with a Section Internationale option. English is taught from Maternelle and increases through primary, making graduates genuinely bilingual French-English.
German International School Sydney
GISS offers a fully bilingual German-English programme leading to both the IB Diploma and the German Abitur. The school is recognised by the German Ministry of Education as a Deutsche Auslandsschule, which means certified German qualifications alongside Australian recognition.
Sydney Japanese International School
SJIS follows the Japanese national curriculum and serves both Japanese expat families and Japanese-Australian dual-citizenship families. English is taught from primary onwards, and the school maintains close links with Japanese tertiary institutions.
Sydney Chinese School
Sydney Chinese School offers Mandarin-English bilingual instruction with a focus on Chinese cultural heritage alongside the NSW curriculum. A solid option for families looking to maintain Mandarin literacy at high levels through secondary school.
International Grammar School
IGS in Ultimo offers an Australian curriculum with a distinctive multilingual programme: every student studies an additional language from Kindergarten (French, German, Italian, Japanese, Mandarin or Spanish) through to senior years. It is one of the few NSW HSC schools where bilingualism is structurally embedded.
Fees you should expect
Annual tuition for primary years typically falls between AUD 18,000 and AUD 28,000 at most bilingual schools, rising to AUD 28,000 to AUD 40,000 for senior years and IB or foreign baccalaureate cohorts. The French Lycée network is partly subsidised by the AEFE and runs slightly below this range for primary years.
Add a one-off enrolment or registration fee of AUD 2,500 to AUD 5,000, an annual building or capital levy at some schools, plus AUD 1,500 to AUD 3,500 for school bus, hot meals, uniforms and excursions. Several schools offer sibling discounts of 5 to 15 percent and modest annual prepayment discounts.
Choosing between bilingual models
If your family expects to return to France, Germany, Japan or another home country within five years, prioritise the foreign national curriculum schools (IFSS, GISS, SJIS) because credential continuity matters. If you are likely to relocate again to a third country, the IB pathway at GISS or other Sydney IB schools offers the broadest international recognition.
If your family is settling permanently in Australia but wants to maintain a second language at near-native level, IGS or one of the Australian independent schools with deep language programmes typically delivers the best balance of NSW HSC strength and bilingual depth.
Admissions and language assessment
Foreign national curriculum schools assess incoming students for the home language (French at IFSS, German at GISS, Japanese at SJIS) but most accept beginners with structured catch-up programmes. IB and Australian schools assess English proficiency primarily, with second-language placement tests used for streaming rather than entry decisions.
Most Sydney bilingual schools open applications nine to twelve months ahead of the January start. Mid-year intakes are accepted at most schools where vacancies exist, particularly in lower primary.
Neighbourhoods and commutes
IFSS and GISS sit on the Lower North Shore, drawing families from Mosman, Cremorne, Lane Cove and Northbridge. SJIS is in the Hills district, well suited to families in Castle Hill and Kellyville. IGS is centrally located in Ultimo, with strong commutes from inner-city neighbourhoods including Surry Hills, Glebe and Pyrmont. Sydney Chinese School has multiple campuses across the city.

Frequently asked questions
Are bilingual schools in Sydney recognised by Australian universities?
Yes. Foreign baccalaureates (French Bac, German Abitur, Japanese senior school certification) and the IB Diploma are all recognised by Australian universities for entry, with ATAR equivalents calculated by UAC for IB and most foreign baccalaureates.
Do my children need French, German, Japanese or Chinese to enrol?
It depends on the school. IFSS, GISS and SJIS prefer some prior exposure but accept beginners with structured language acquisition support. IGS and most IB schools start from no prior knowledge and build language skills from Kindergarten upwards.
How do bilingual school fees compare to top Sydney independent schools?
Bilingual international schools typically charge slightly less than the most established Sydney independents (Cranbrook, Kambala, Sydney Grammar) but more than mid-tier Catholic and faith-based independents. The bilingual premium is usually 10 to 20 percent below the very top of the market.
