Little Australia is a name for any of the various communities where Australians congregate upon emigrating to other countries, examples can be found in the United States, Canada and the United Kingdom. The concept of "Little Australia" holds many different aspects of the Australian culture. Common features include shops selling Australian goods and Australian restaurants lining the streets. A "Little Australia" strives essentially to have a version of the country of Australia placed in the middle of a big non-Australian city.
Mulberry Street, Manhattan
Since 2010, a Little Australia has emerged and is growing in Nolita, Manhattan, New York City. Mulberry Street in Lower Manhattan is commonly referred to by Australian expats as "Little Australia" due to the influence of Australian and New Zealand cafe culture in the area, which includes establishments such as Ruby's, Two Hands, and Happy Bones. Little Australia is adjacent to Little Italy and Chinatown, Manhattan in Manhattan. Avocado on toast or colloquially referred to in Australia as "Avo on toast" and "Smashed Avo"  is a uniquely Australian breakfast staple that many New Yorkers mistake for being an invention of their own.
Earl's Court, London
When Barry Humphries went (by sea) to London in 1959, he and Ros lived in Ladbroke Grove in Kensington. He made an impromptu visit to an Earl's Court pub, smack in the middle of Kangaroo Valley, as it was sometimes called. He fell physically ill and frightened by what he saw. The packs of loutish Australian youths swilling beer and swearing revived painful memories of the bullies at Melbourne Grammar. 
In 1962 Clive James went (also by sea; only one friend could afford to fly) to London with a weeks accommodation booked in Earl's Court, which in those days was still nicknamed "Kangaroo Valley". He said that there was no mistaking the Earl's Court Australians ... with jug ears, short haircuts .... and open, freckled, eyeless faces despite their navy-blue English duffle-coats; though they had not yet taken to carrying twelve-packs of Foster's Lager, and the broad-brimmed Akubra hat with corks dangling from the brim was never to be more than a myth. After he moved, he vowed never to enter Earl's Court again.

In Little Australia, Australian-owned cafes are popping up all over the place (such as Two Hands), joining other Australian-owned businesses (such as nightclubs and art galleries) as part of a growing green and gold contingent in NYC. Indeed, walking in this neighbourhood, the odds of your hearing a fellow Aussie ordering a coffee or just kicking back and chatting are high – very high – so much so that if you’re keen to meet other Aussies whilst taking your own bite out of the Big Apple, then this is the place to throw that Australian accent around like it’s going out of fashion!
