Religion in Australia is diverse. Section 116 of the Constitution of Australia of 1901 prohibits the Commonwealth government from establishing a church or interfering with the freedom of religion.[note 1] In an optional question on the 2016 Census, 52.2% of the Australian population declared some variety of Christianity. Historically the percentage was far higher; now, the religious landscape of Australia is changing and diversifying.[1] In 2016, 30.1% of Australians stated "no religion" and a further 9.6% chose not to answer the question.[1] Other faiths include Muslims (2.6%), Buddhists (2.4%), Hindus (1.9%), Sikhs (0.5%), and Jews (0.4%).[1]As per the 2016 Census, Sikhism is the fastest growing religion in Australia which showed a 74% increase from the 2011 census followed by Hinduism(60% increase) and Irreligion(48% increase).[3]
