In colonial New South Wales marriage was often an arrangement of convenience. For female convicts, marriage was a way of escaping incarceration. Land leases were denied to those who were unmarried. On the other hand, there was a significant gender imbalance in the colony. Until 1961, each Australian state and territory administered its own
marriage laws. The
Marriage Act 1961 (Cth) was the first federal law on the matter and set uniform Australia-wide rules for the recognition and solemnisation of marriages. In its current form, the Act recognises only
monogamous (heterosexual or same-sex) marriages and does not recognise any other forms of union, such as traditional
Aboriginal marriages In 2004, the Liberal
Howard government enacted the
Marriage Amendment Act 2004 to expressly ban same-sex marriage in Australia. It defined
marriage as "the union of a man and a woman to the exclusion of all others, voluntarily entered into for life". Until the enactment of the 2004 amendment, there was no definition in the 1961 Act of "marriage", and the
common law definition used in the English case
Hyde v Hyde (1866) was taken as applicable. The definition pronounced by Lord Penzance in the case was: "I conceive that marriage, as understood in Christendom, may for this purpose be defined as the voluntary union for life of one man and one woman, to the exclusion of all others". The 2004 amendment also banned the recognition of same-sex marriages performed in a foreign country. The definition of marriage was added to the wedding ceremony speeches as a monitum; without it, ceremonies would be considered invalid. In 2009, the Labor
Rudd government enacted the
Family Law Act 2009, which recognised the property rights of each partner of a
de facto relationship, including a same-sex relationship, for the purposes of the
Family Law Act 1975. The 2014
Marriage Amendment (Celebrant Administration and Fees) Act amended the
Marriage Act 1961 in relation to celebrants and other issues. The 2017
Marriage Amendment (Definition and Religious Freedoms) Act again changed the definition of "marriage" under the
Marriage Act 1961, replacing the words "a man and a woman" with "2 people" and therefore allowing monogamous same-sex marriages. The Act also reversed the 2004 Amendment and retrospectively recognised same-sex marriages performed in a foreign country, provided that such marriages were permitted under the laws of that foreign country. ==Social change==
