In Australia (as it stands at the moment) people are free to practise any spirituality, religion, philosophy, etc they choose to, as long as it does not restrict or violate the state or federal law. The terms spirituality, religion and philosophy covers Religion, Non-Religion, New Age Religions and other spirituality and philosophies such as Scientology. It is impossible to have a fair and reasonable society if there is no freedom of religion or for that matter if religion plays a part in the government of a nation. To this end the constitution of Australia guarantees freedom of religion or no religion.
