Many Western nations permit celebrants who are not clergy to carry out basic, legal, marriage ceremonies. However Australia was the first nation whose government appointed non-clergy celebrants (19th of July, 1973) with the specific intention that they would create ceremonies that might be as culturally enriching and, if required, as formal as church weddings, i.e. that these ceremonies would not be inferior in status to religious weddings.

An "authorised celebrant" is a person who is authorised (registered) by the Australian Government to perform legal marriages according to the Marriage Act 1961.

The celebrant may be a representative of a religious organisation (known as a religious marriage celebrant) or someone providing secular or non-religious weddings (known as a civil marriage celebrant). Only authorised (registered) marriage celebrants have the authority to perform marriages in Australia.

In 2016, 76.4 per cent of Australian marriages were performed by civil celebrants.
