One of the core principles of Australia’s democracy is that it does not allow religious institutions to directly influence the decisions of government. While Christianity is the most widespread religion in Australian society, the church has never been directly involved in running the country. This separation of church and state is known as secularism and is a key feature of Australia’s identity as a nation. As a secular nation, Australia is able to encourage a diverse society that gives its people the freedom to choose their religious beliefs. Australia’s public health, education and political institutions are all free from religious connections. This ensures that religious beliefs of one group of people are not forced onto Australians of other faiths. It also means that decisions about what is best for today’s society can be made through open discussion. Despite being a secular nation, religions still influence the beliefs and decisions of many Australians who, as both voters and politicians, determine how the nation is governed. While most nations around the world today adopt a secular system of government, some nations, such as Iran and Saudi Arabia, base their legal system on religious teachings.
