Why do some Sydney suburbs have Greek or Italian character?

The presence of Greek and Italian character in certain Sydney suburbs is a direct result of the large-scale immigration that occurred in the period following World War II.2

During the postwar years, Australia experienced a massive influx of migrants, shifting the nation from a previously monocultural, British-oriented society toward a multicultural one. By 1961, Italians and Greeks represented some of the largest migrant groups arriving in the country. Many of these newcomers settled in Sydney, particularly within its inner suburbs, where they established communities that retain a distinct cultural character to this day. This demographic shift significantly enriched the city's social fabric, contributing to the diversity of ethnic restaurants and cultural influences found throughout Sydney's suburbs.12
