In a series of letters, a P. Cunningham, stated that a St Patrick's Day "jubilee" Ball was being held in Sydney in 1826. The situation changed, however, in the 1830s with the growth of wealthy Irish Catholic emancipists and the introduction of Irish Catholic priests. These factors gave rise to conflicts and tensions that were to remain constant thereafter as the rise and decline of domestic Irish political movements influenced the Irish population in Australia. With the outbreak of World War I, imperatives imposed by the demands of war overshadowed Australian Irish sentiment. The idea of fraternity and how to organise it was one of 19th-century Europe's invisible exports to the New World. Fitzpatrick (2005) explores the international diffusion of the Loyal Orange Institution, with comparative reference to Freemasonry, its main model. Three alternative explanations are discussed for its appeal outside Ireland: that it facilitated the assimilation of emigrants, transmitted 'tribal' Irish animosities to fresh contexts, or adapted itself to preexisting sectarian rivalries abroad. These hypotheses are tested using evidence from South Australia, where Orangeism flourished in the absence of heavy Ulster Protestant immigration. A collective profile of Orange South Australia is derived from lodge records showing age, religious denomination, and occupation, and the appeal of Orangeism is related to local political and religious contexts. In this case, Orangeism was primarily an export of organisational techniques rather than Irish personnel or bigotry. The Catholic Church in Australia maintained a strong Irish identity, especially in the decades from the 1880s to the 1960s when state aid for church schools was withdrawn and the Church maintained a separate and separately funded school system. The leadership of the Australian Church was almost entirely Irish from 1883 to 1940, prominent Irish-born bishops including Cardinal Moran and Archbishop Kelly in Sydney, Archbishops Carr and Mannix in Melbourne and Archbishop Duhig in Brisbane. Many of the Catholic schools were run and staffed by Irish orders of nuns such as the Sisters of Mercy and Brigidines and Irish orders of brothers such as the Christian Brothers and Patrician Brothers. The Sisters of Charity worked in hospitals. McGrath (1995) demonstrates the success of the Catholic nuns who arrived in Parramatta, New South Wales, from Ireland in 1888, noting their group's growth from nine newcomers into a flourishing congregation of over two hundred women within sixty years. By the 1950s this group of women religious was responsible for 24 primary schools, five secondary schools, and two orphanages. In Australia they carried on the Irish tradition of the Sisters of Mercy and lived a monastic lifestyle.
