Major Migrant Groups to Australia: British, Irish, Chinese, Italians, Greeks

Australia's migration history unfolds in waves. The five largest ancestral groups (by ancestry response, 2021 Census) shaped the nation:

1. British & Irish (Anglo-Celtic) — 33% Combined Ancestry

• British: 1788–present. Convicts (162,000, 1788–1868), free settlers, assisted passages (19th C), £10 Poms (1947–1982). Cultural/institutional foundation.
• Irish: 1790s–present. Convicts (25% of transportees), famine refugees (1840s), post-WWII. Catholic identity, labor politics, cultural distinctiveness.

2. Chinese — 5.5% Ancestry (1.4M)

• Gold rushes (1850s): 40,000+ arrivals; discrimination (poll tax, riots)
• White Australia Policy (1901–1973): Exclusion, then gradual reopening
• Post-1970s: Vietnam War refugees, Hong Kong handover (1990s), mainland students/skilled migrants (2000s+). Now largest non-European ancestry.

3. Italian — 3.7% Ancestry (950K)

• Pre-WWII: Chain migration (Veneto, Calabria, Sicily) — sugarcane (QLD), mining (WA), fisheries
• Post-WWII (1950s–70s): 300,000+ assisted — construction, manufacturing (Holden, Ford), Snowy Hydro
• Legacy: Coffee culture, wine, Calabria/Victoria dialects, family enterprises

4. Greek — 1.8% Ancestry (460K)

• Pre-WWII: Chain migration (islands, Asia Minor refugees 1922)
• Post-WWII: 1950s–70s assisted — factories, cafes, fish shops
• Cyprus refugees (1974): Additional wave
• Legacy: Orthodox Church, festivals (Antipodes, Glendi), Melbourne = largest Greek pop. outside Greece

5. Post-1970s Diversification

Vietnamese, Indian, Filipino, Lebanese, Sri Lankan, Sudanese, Afghan, Iraqi, Syrian — each 1–2% ancestry. 2021: 29% born overseas; 48% have ≥1 parent born overseas.

These five "foundation waves" built Australia's institutions, but the nation's demographic center of gravity has shifted decisively toward Asia-Pacific.
