The term Australian diaspora may refer to the approximately 1,000,000 Australian citizens (approximately 5.2% of the population) who today live outside Australia. This usage of the term includes the several hundred thousand people who spend some time in the United Kingdom and Europe but return to Australia. The Trans-Tasman Travel Arrangement made it easy for Australians to migrate into New Zealand and vice versa. Key factors influencing this phenomenon are seen to include the rise of a global labour market, more accessible and economical international transport, and increasingly sophisticated communication technologies, along with a growing interest in travel and the broader global community.
Origin of the term
The term Australian diaspora was used in reference to Australian citizens living abroad in a 2003 Committee for Economic Development of Australia (CEDA) research report, "Australia's Diaspora: Its Size, Nature and Policy Implications".
