Despite inclusion in the "States" chapter, Section 116 does not apply to states because of changes during drafting, and they are free to establish their own religions. Although no state has ever introduced a state church (New South Wales restricted religious groups during the early colonial period), the legal body corresponding to many religious organisations is established by state legislation. There have been two referenda to extend Section 116 to states, but both failed. In each case the changes were grouped with other changes and voters did not have the opportunity to expressly accept only one change. Most states permit broad exemptions to religious groups from anti-discrimination legislation; for example, the New South Wales act allowing same-sex couples to adopt children permits religious adoption agencies to refuse them.
