duties before being arrested and deported to London. Reaction to the affair in Britain led to two further priests being allowed to travel to the colony in 1820. The Church of England was disestablished in the Colony of New South Wales by the Church Act of 1836. Drafted by the Catholic attorney-general John Plunkett, the act established legal equality for Anglicans, Catholics and Presbyterians and was later extended to Methodists. By the late 19th century approximately a quarter of the population of Australia were Irish Australians. Many were descended from the 40,000 Irish Catholics who were transported as convicts to Australia before 1867. The majority consisted of British and Irish Protestants. The Catholics dominated the labour unions and the Labor Party. The growth of school systems in the late 19th century typically involved religious issues, pitting Protestants against Catholics. The issue of independence for Ireland was long a sore point, until the matter was resolved by the Irish War of Independence. Limited freedom of belief is protected by Section 116 of the Constitution of Australia, but sectarianism in Australia was prominent (though generally nonviolent) in the 20th century, flaring during the First World War, again reflecting Ireland's place within the Empire, and the Catholic minority remained subject to discrimination and suspicion. During the First World War, the Irish gave support for the war effort and comprised 20% of the army in France. However, the labour unions and the Irish in particular, strongly opposed conscription, and in alliance with like-minded farmers, defeated it in national plebiscites in 1916 and 1917. The Anglicans in particular talked of Catholic "disloyalty". By the 1920s, Australia had its first Catholic prime minister. During the 1950s, the split in the Australian Labor Party between allies and opponents of the Catholic anti-Communist B.A. Santamaria meant that the party (in Victoria and Queensland more than elsewhere) was effectively divided between pro-Catholic and anti-Catholic elements. As a result of such disunity the ALP was defeated at every single national election between 1955 and 1972. In the late 20th century, the Catholic Church replaced the Anglican Church as the largest single Christian body in Australia; and it continues to be so in the 21st century, although it still has fewer members than do the various Protestant churches combined. While older sectarian divides declined, commentators have observed a re-emergence of anti-Catholicism in Australia in recent decades amid rising secularism and broader
