The history of the Australian American population almost follows the story of both British Americans and Irish Americans, as Australia was a British political territory at the time when they first immigrated and most of the settlers were English or Irish. The first wave of immigration from Australia to the United States came in the 1850s California Gold Rush when mostly Irish migrants who had escaped the Great Irish Famine had previously worked on the Australian goldfields. In San Francisco, the " Sydney Ducks" as they were known came into violent conflict with nativist locals. Transpacific immigration then dried up while the American Civil War took place. It picked up during the period of Reconstruction, but faltered again when Australia was hit by an economic depression in the late 1890s. Immigration to the United States peaked in the years following World War II, due to America's increased economic activity, and the exodus of 15,000 Australian war brides who married U.S. servicemen. From 1971 to 1990, more than 86,400 Australians and New Zealanders immigrated to the United States.  At the 2000 U.S. Census, 60,965 Australian born people were enumerated in the United States, of which 15,315 were citizens. Around 40% of Australian Americans had entered the United States before 1980.  Since 2010, a Little Australia has emerged and is growing in Nolita, Manhattan, New York City.

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!
