South West Sydney is home to one of Australia’s largest Southeast Asian diaspora communities. This Southeast Asian SW Sydney research explores the scale, patterns, and composition of these communities using 2021 Census data — getting an exact count is harder than you’d think, but the patterns the data reveals are worth understanding.
The scale
Across Fairfield, Liverpool, Canterbury-Bankstown and Campbelltown: approximately 128,000 people of Southeast Asian heritage.
That’s roughly 12% of Australia’s entire Southeast Asian population in just four local government areas.
About 100,000 were born overseas. The rest are Australian-born descendants — second and third generation.
Why these are estimates, not exact counts
No single Census measure captures everyone. Ancestry, country of birth, and language spoken at home overlap. Someone born in Vietnam who speaks Vietnamese gets counted three times if you’re not careful.
Our figures are derived from 2021 Census data, cross-checked against spatial patterns and local research. They’re solid estimates — but estimates, not gospel.
Community breakdown
Three key patterns
Vietnamese ancestry dominates: ~82,000 people. In Fairfield alone, 19.5% of the population. In Cabramatta specifically: 37.8% — nearly 1 in 3.
Filipino communities are dispersed: Unlike Vietnamese and Cambodian populations (clustered around Fairfield/Bankstown rail lines), Filipinos are spread wider, with recent growth in Campbelltown and Liverpool driven by skilled migration in healthcare. (Note: Blacktown in Western Sydney also has significant Filipino population, but falls outside this South West Sydney analysis.)
The Hoa layer: Thousands identify as ethnically Chinese while their origin is Vietnam or Cambodia. This adds an estimated 15,000–20,000 to the real footprint — but they’re often invisible in “Southeast Asian” counts.
Why this matters
Understanding the demographic baseline — who’s where, in what numbers — is foundational for policy, community development, and business planning in South West Sydney.
