At the 2006 census, 150,873 persons resident in Australia identified themselves as being of Korean ancestry, either alone or with another ancestry. 52,760 persons resident in Australia had been born in South Korea and 59 born in North Korea.
Only 38% declared holding Australian citizenship, 68% had arrived in Australia in 1990 or later, and 63% reside in New South Wales. Few ethnic groups are as concentrated in one state as Koreans are in New South Wales, where 33% of Australia's population live.
At the 2006 Census, 37,426 (71%) Korean-born Australian residents declared they were Christian, 3,500 (6.6%) Buddhist and 9,562 (18%) had no religious affiliation. Disgruntled former members of Korean Christian churches sometimes join the handful of Korean Buddhist temples in the Sydney area.
