[1][C] The precise number of Anglo-Celtic Australians is unknown due to the way in which ancestry data is collected in Australia.[citation needed] Native-born Australians of British and Irish descent were approximately a quarter of the population of the colony of New South Wales in both 1817 and 1828.[10] From the beginning of the colonial era until the mid-20th century, the vast majority of settlers to Australia were from Britain and Ireland, with the English being the dominant group, followed by the Irish and Scottish.These reporting shifts at least partly resulted from changes in the design of the census question, in particular the introduction of a tick box format in 2001.At the 2021 census, the most commonly nominated Anglo-Celtic ancestries were:[1] The United Kingdom remains a significant source of immigrants to Australia.On the evidence of statistics of ethnic derivation Tasmania could also be considered more British than New Zealand (where the Anglo-Celtic majority has fallen below 75 percent).[44]The Irish-Australian journalist Siobhán McHugh has argued that the term "Anglo-Celtic" is "an insidious distortion of our past and a galling denial of the struggle by an earlier minority group", Irish Australians, "against oppression and demonisation...In what we now cosily term "Anglo-Celtic" Australia, a virtual social apartheid existed at times between [Irish] Catholics and [British] Protestants", which did not end until the 1960s.The term was also criticised by the historian Patrick O'Farrell as "a grossly misleading, false, and patronising convenience, one crassly present-oriented.Its use removes from consciousness and recognition a major conflict fundamental to any comprehension not only of Australian history but of our present core culture.There is a long history of cultural exchange between the countries and many Australians have used Britain as a stepping-stone to international success, e.g., Nellie Melba, Peter Dawson, Clive James, Robert Hughes.[46] Queensland – The state was named in honour of Queen Victoria,[48][49] who on 6 June 1859 signed Letters Patent separating the colony from New South Wales.
