Sydney is one of the most multicultural cities in the world, with more than a third of residents born overseas and significant French, German, Japanese, Korean, Chinese and Spanish-speaking communities. For families who want their children to grow up genuinely bilingual rather than just bilingual on paper, Sydney offers a small but high-quality cluster of international schools running structured immersion or dual-language programmes. This 2026 family guide profiles the strongest bilingual international schools in Sydney, lays out fee bands and explains how to think about choosing the right language pathway for your child.
Bilingual education in Sydney: how it works
Sydney's bilingual landscape is dominated by national-system schools (French, German, Japanese) operating under their home country's curriculum, plus a handful of Australian schools running serious bilingual primary streams. Most lead to either the home-country secondary qualification (French Bac, German Abitur), the IB Diploma or the New South Wales HSC. The right choice depends on whether your stay in Australia is short-term or long-term, and which universities your child is most likely to apply to.
Top bilingual international schools in Sydney
The International French School of Sydney
Lycée Condorcet is an AEFE-accredited French school running the full French national curriculum from maternelle to terminale, leading to the French Bac. About half of the timetable is delivered in French and half in English from primary onwards, which makes it a strong fit for both French-speaking families and Anglophone families who want a serious immersion route into French.
German International School Sydney
GISS delivers a bilingual German-English programme from preschool through to Year 12 and offers both the New South Wales HSC and the German International Abitur. The school is recognised by the German Federal Foreign Office and is the natural choice for German-speaking families and for English-speaking families committed to a long German pathway.
Sydney Japanese International School
SJIS offers two streams: a Japanese national curriculum stream for children whose families intend to return to Japan, and an international stream delivering a bilingual English-Japanese programme leading to the IB. It is one of very few schools in Australia offering serious Japanese-medium primary education.
International Grammar School
IGS is an Australian co-educational school based in Ultimo with a unique multilingual primary programme: every primary student studies one of French, German, Italian, Japanese or Mandarin throughout their first six years. Secondary students continue language study and graduate with the NSW HSC.
Fees and what to budget
For 2026, plan for:
- French International School of Sydney: AUD 14,500 to AUD 26,000 a year depending on year group, with subsidies available for French nationals.
- German International School Sydney: AUD 19,000 to AUD 32,000 a year.
- Sydney Japanese International School (international stream): AUD 14,000 to AUD 25,000 a year.
- International Grammar School: AUD 30,000 to AUD 45,000 a year for primary and secondary.
Add a one-off enrolment fee of AUD 2,000 to AUD 5,000, uniforms, lunch and a bus pass, plus external exam fees in IB DP and Bac years.
Choosing the right bilingual pathway
- If you may return to Europe within the next 4 to 6 years, a French Bac or German Abitur pathway preserves direct access to home-country universities.
- If you plan to stay in Australia long term, a school combining the HSC or IB with a strong language stream (IGS, GISS) is the safer bet.
- If your child is older than 8 and not yet bilingual, plan a 2-year ramp-up. Most schools offer language support but immersion takes time.
- If university is in the US, both the HSC and the IB are well accepted; the German Abitur and French Bac are also recognised but require explanation in transcripts.

Frequently asked questions
Are bilingual schools in Sydney accepted by Australian universities?
Yes. Schools offering the HSC, IB Diploma, French Bac, German Abitur or Japanese Senior High pathways are all recognised entry routes for Australian universities through ATAR equivalence.
Will my Anglophone child cope in a French or German bilingual school?
Younger children typically settle within a year. From Year 3 upwards schools usually require some prior language exposure, so an immersion summer programme or private tutoring before starting is a useful investment.
Are bilingual schools in Sydney cheaper than full Australian private schools?
French and Japanese international schools are typically more affordable than top tier Sydney private schools. The German International School and IGS sit at a similar price point to mid-tier private schools in the city.
