In 1947 there were 1,024 Greek South Australians.

There was a considerable influx of Greek migrants during the post-war period. In the aftermath of its occupation by the Axis powers from 1941 until 1945, the administration, economy and politics of Greece were in a chaotic condition. Many single men migrated to South Australia from the Peloponnese, Crete, Lesbos, Cyprus, Dodecanese, Epirus, Macedonia, and even from well-established Greek settlements in Egypt and the Middle East. They also came from European nations around Greece and from the Americas, South Africa, the Philippines, the Soviet Union and Asia Minor. Often they were sponsored by relatives already settled in South Australia. Once established, they were later joined by family groups and relatives.

In 1952 the Australian government completed an agreement with the Inter-Governmental Committee for European Migration and the Greek government. From this arrangement, selected workers and families were able to come to Australia as assisted immigrants. The Australian Council of Churches also began a migrant-aid scheme of its own. In 1953 the council made travel loans available to many Greeks who wanted to settle in Australia.

During the early 1950s the ratio of Greek males to females in Australia was 5 to 1. As a result, in the following years, young single Greek women were given special assistance to come to Australia. Some were sponsored by Greeks already settled here. Many of these young women married Greek men and established families.

At this time the Greek Orthodox Community of South Australia had a membership of approximately 3,500. The community needed a centre which could accommodate the needs of its members. After a period of fundraising the Greek Community Centre was opened in 1957. The centre is a large, multipurpose building, consisting of Olympic Hall and numerous rooms used for educational, cultural and social activities. Greek South Australians used these facilities to assist post-war refugees who were arriving in Adelaide. They helped new arrivals with language, health, legal, educational and employment problems.

During the 1950s and 1960s, many Greek arrivals in South Australia were employed on two-year contracts with the Australian government. They worked as farmers on Eyre Peninsula or in Mount Gambier, or in factories and other places where unskilled labour was sought. Greeks worked in ship building in Whyalla, fishing in Port Lincoln and as fruit pickers and growers in the citrus, stone and dried fruit industries of Renmark and Berri. Others migrated to Port Pirie and joined the substantial Greek community already there. Significant numbers established communities in Adelaide’s western area, particularly Mile End and Thebarton. During this time Greek schools and churches were established throughout South Australia and Adelaide.

In 1961 there were 9,528 Greek South Australians. By 1966 there were 14,660.
