On 9 December 2017 legislation to allow same-sex couples to marry in Australia was passed into law. The Marriage Amendment (Definitions and Religious Freedoms) Act 2017 redefines the definition of marriage in Australia as:
‘the union of 2 people to the exclusion of all others, voluntarily entered into for life’
Other requirements for getting married in Australia have not changed. Couples are still required to lodge a Notice of Intended Marriage with their preferred Authorised Marriage Celebrant at least one calendar month before their desired marriage date.
