Since the arrival of the First Fleet of British ships in 1788, Christianity has become the major religion practised in Australia. Christian churches have played an integral role in the development of education, health and welfare services in Australia. For much of Australian history, the Church of England (now known as the Anglican Church of Australia) was the largest religious denomination, with a large Roman Catholic minority. However, multicultural immigration has contributed to a steep decline in its relative position since the Second World War. Similarly, Islam, Buddhism, Hinduism, Sikhism and Judaism have all grown in Australia over the past half-century.
