Londoners joke pubs would close without Australian bar staff – and the maps show how many of the country's citizens are in the capital.
106,000 Australia-born people were in Britain in 2001 – four of every 10 of them in London.
Many of today's Australian-born in Britain are under-30s who come on work visas after studies as a means of financing a year-long tour of the world. Scotland ranks unusually highly as a destination for Australian-born people, possibly indicating historic family routes.
Some people born in Australia will be children of British families who lived abroad, possibly having emigrated in the 1970s, before returning at a later date.
