Religion Australia

Australia has no state religion; Section 116 of the Australian Constitution prohibits the federal government from making any law to establish any religion, impose any religious observance, or prohibit the free exercise of any religion. In the 2016 census, 54.6% of Australians were counted as Christian, including 22.6% as Roman Catholic and 13.3% as Anglican; 30.1% of the population reported having "no religion"; 7.3% identify with non-Christian religions, the largest of these being Islam (2.6%), followed by Buddhism (2.5%), Hinduism (1.9%), Sikhism (0.6%) and Judaism (0.4%). The remaining 9.6% of the population did not provide an adequate answer. Those who reported having no religion increased conspicuously from 19% in 2006 to 30% in 2016. The largest change was between 2011 (22%) and 2016 (30.1%), when a further 2.2 million people reported having no religion.
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. However, multicultural immigration has contributed to a decline in its relative position, and the Roman Catholic Church has benefitted from recent immigration to become the largest group. Similarly, Islam, Buddhism, Hinduism, Sikhism and Judaism have all grown in Australia over the past half-century.
Australia has one of the lowest levels of religious adherence in the world. In 2001, only 8.8% of Australians attended church on a weekly basis.
