Australians in the United Kingdom include Australians who have become residents or citizens of the United Kingdom. The largest segment of Australia's diaspora of 1 million resides in the United Kingdom.
The 2001 UK Census recorded 107,871 Australian-born people. In that census, the highest concentration of Australians in the UK was recorded in south-west London, with sizeable communities in Earl's Court, Kensington, Hammersmith, Fulham, Shepherds Bush and Putney. In 2007, Bloomberg reported that there were approximately 200,000 Australians in London. In 2008, The Times reported that there were 400,000 Australians in the United Kingdom. The 2011 UK Census recorded 113,592 residents born in Australia in England, 2,695 in Wales, 8,279 in Scotland, and 1,750 in Northern Ireland. The Office for National Statistics estimates that 113,000 people born in Australia were resident in the UK in 2013.
The late-2000s recession resulted in increased number of Australians moving from the UK. 2,700 Australians left each month in late 2008, compared to 1,750 a month in 2005.
