Sectarianism in Australia tended to reflect the political inheritance of Britain and Ireland. Until 1945, the vast majority of Catholics in Australia were of Irish descent, causing the Anglo-Protestant majority to question their loyalty to the British Empire. The Church of England remained the largest Christian church until the 1986 census. After World War II, the ethnic and cultural mix of Australia diversified and the Church of England gave way to the Catholic Church as the largest. The number of Anglicans attending regular worship began to decline in 1959 and figures for occasional services (baptisms, confirmations, weddings and funerals) started to decline after 1966.
