How did immigration after World War II change South Australia’s population?

Following World War II, South Australia experienced a significant demographic shift that transformed its population from a largely homogeneous, British-descended society into a diverse, multicultural one.12

Between 1947 and 1966, the state underwent a period of rapid population growth driven by a government-fostered immigration program designed to support the state's expanding manufacturing sector. This era brought large numbers of people from continental Europe—notably Italy, Greece, Germany, the Netherlands, Poland, and Yugoslavia—alongside a substantial inflow of British migrants.12

These post-war waves of migration were instrumental in altering the state's character, moving it away from its earlier, more uniform demographic profile. While immigration patterns shifted in the late 20th century to include more arrivals from Southeast Asia and New Zealand, the post-war period remains the defining era for the state's transition toward its current multicultural identity.21
