Berlin and Sydney both serve expat families well, but in opposite ways. Berlin offers a compact, affordable European IB market. Sydney offers a deep independent school sector built around the NSW Higher School Certificate, with IB available at a smaller cluster of independents. Most expat families weigh school depth and outdoor lifestyle against cost and EU connectivity.
Schools landscape side by side
Berlin's shortlist is short but strong: Berlin Brandenburg International School (BBIS) in Kleinmachnow for the only full IB continuum in the region, Berlin International School in Charlottenburg, Berlin British School across Charlottenburg and Grunewald, and the John F Kennedy School for German and US bilingual families. Capacity is reasonable outside Year 7 and Year 12. State-recognised bilingual schools fill the budget tier at EUR 3,000 to 8,000 per year.
Sydney is dominated by the independent and Catholic school sector rather than dedicated international schools. Expat families typically shortlist Sydney Grammar, SCEGGS Darlinghurst, Cranbrook, Knox Grammar, Pymble Ladies' College, MLC School and Newington College for traditional Australian independents, or the International Grammar School (IGS) and Australian International School for the IB Diploma route. Demand is heavy at the elite independents, often booked by birth, and expat-friendly schools like IGS and Inaburra are easier to secure within a single term.

Fees and value for money
Berlin is one of the most affordable Western European postings for international school families. Premium IB and British schools charge EUR 14,000 to 22,000 for primary and EUR 18,000 to 28,000 for secondary. Bilingual schools with public subsidies sit at EUR 3,000 to 8,000. Capital fees of EUR 500 to 3,000 apply at most private schools. See our Berlin fees guide for the full picture.
Sydney is materially more expensive at the premium tier. Elite independents publish primary fees of AUD 25,000 to 42,000 and senior secondary fees of AUD 38,000 to 56,000 (roughly USD 25,000 to USD 37,000). Add capital levies of AUD 1,500 to 4,000 per year and enrolment bonds. Mid-tier independents and Catholic systemic schools are dramatically cheaper at AUD 8,000 to 18,000 per year. Use the cost calculator to model the right tier for your role.
Curriculum availability
Berlin tilts IB and British, with a German bilingual stream that suits long-term Berlin families and feeds German universities through the Abitur. The IB Diploma at BBIS and Berlin International School is the most portable choice for families on shorter postings. Cambridge IGCSE and A Level run at Berlin British School.
Sydney is HSC-dominant at most independents, with the NSW Higher School Certificate the default. The IB Diploma is available at IGS, the Australian International School, Trinity Grammar, Newington and a handful of others. AP is rare. Visit the IB hub for context on how the Diploma compares with the HSC for university entry.
Neighbourhoods families pick
Berlin families cluster in Mitte for transport access, Charlottenburg and Wilmersdorf for proximity to Berlin International School, Grunewald and Zehlendorf for leafy streets near the John F Kennedy School and Berlin British School, and Kleinmachnow in Brandenburg for the BBIS catchment. A three bedroom family flat in central Berlin runs EUR 2,200 to 3,800 per month; a detached house in Zehlendorf or Kleinmachnow EUR 3,000 to 5,500.
Sydney families cluster in the Eastern Suburbs (Bondi, Bellevue Hill, Vaucluse) for Cranbrook and SCEGGS catchment, the Lower North Shore (Mosman, Cremorne) for Knox and Loreto, and the Northern Beaches for family-friendly access to schools like Pittwater House. An eastern suburbs three bedroom apartment runs AUD 4,500 to 7,500 per month; a North Shore family house AUD 5,500 to 9,500.
Lifestyle and climate
Berlin has cool grey winters and short mild summers around 22 to 26 degrees Celsius, with extensive green space, cheap public transport and a strong cultural offering. Sydney has a temperate maritime climate with mild winters around 14 degrees Celsius and warm dry summers around 26 to 32 degrees Celsius. Outdoor life defines a Sydney childhood: beaches, sailing, surf clubs and rugby league fill weekends. Berlin offers easy EU travel to Vienna, Prague and Amsterdam; Sydney offers easier access to Pacific destinations, New Zealand and Southeast Asia. Both cities are very safe by global standards.
Verdict: who picks which city
Choose Berlin if affordable IB schools, a safe European city and easy weekend travel across the EU matter most. It suits families who want a balanced cost base, strong culture and a posting that integrates them into the EU professional market.
Choose Sydney if outdoor childhood, English-language schooling and the Pacific lifestyle matter most. It suits families with a long-term skilled visa or PR pathway, where the children integrate into Australian university and career systems. The premium independent tier suits roles that can carry AUD 38,000 to 56,000 per child in tuition.
Run both cities through the cost calculator. The five year all-in delta on housing plus tuition is usually USD 100,000 to 200,000 in Berlin's favour at the premium tier, but Sydney wins on outdoor lifestyle and English-only schooling.
Frequently asked questions
Is Berlin or Sydney cheaper for international school families in 2026?
Berlin is meaningfully cheaper. Sydney costs roughly 25 to 35 percent more overall, with premium school fees often double Berlin's IB or British school rates, and central housing significantly more expensive.
Which city has better international schools?
Sydney has the deeper independent sector with elite schools like Sydney Grammar, SCEGGS, Cranbrook and Knox. Berlin's BBIS and Berlin International School are credible Tier 1 IB choices but the bench is shallower. The IB Diploma is more widely available in Berlin; the HSC dominates in Sydney.
Is the family visa easier in Berlin or Sydney?
Berlin is easier for EU nationals via free movement and reasonably accessible for skilled non-EU professionals via the Blue Card. Sydney requires a skilled visa (482 TSS or 186 ENS) that includes dependants, which is well-trodden but slower and more rigid than the Schengen route.
Does the IB Diploma get into Australian universities?
Yes. The IB Diploma is recognised by all Australian universities and is converted to ATAR-equivalent scores by UAC. Outcomes from Sydney IB schools are strong for both Australian and international university pathways.
Where do most international school families live in each city?
Berlin families cluster in Mitte, Charlottenburg, Wilmersdorf, Grunewald, Zehlendorf and Kleinmachnow. Sydney families cluster in Bondi, Bellevue Hill, Vaucluse, Mosman, Cremorne and the Lower North Shore.
