Same-sex marriage is set to be legalised in Australia by the end of 2017 after 61.6 per cent of respondents in the country's Marriage Law Postal Survey voted Yes. 

But for 25 countries around the world it’s already a right - and has been in several countries for more than a decade.

In most cases marriage equality has been legislated by parliaments, but in several cases constitutional courts have forced the government's hand.

More than 840 million people now live in countries where same-sex marriage is legal.

2001 – The Netherlands

The Netherlands was the first country to pass legislation to allow same-sex couples to legally marry, divorce and adopt children.

The law passed by a three-to-one margin.

2003 – Belgium

Belgium’s parliament voted to allow same-sex marriage in 2003, with legislation in 2006 granting same-sex couples the right to adopt children.

2005 – Spain and Canada

In 2005 Canada became the first country outside of Europe to legalise same-sex marriage. Parliament passed legislation after a steady march of court rulings had legalised the practice in the majority of the country’s provinces.

The Conservative Party attempted to repeal the legislation one year later but was defeated.

Spain’s parliament narrowly passed some of the world’s most liberal marriage equality laws in 2005, extending full rights to same-sex couples.

The move saw protests from Catholic officials and brought large crowds to the streets in Madrid.

2006 – South Africa

South Africa’s parliament legislated for same-sex marriage in 2006, codifying a 2005 court decision which found that restricting marriage to heterosexuals was discriminatory and unconstitutional.

It remains the only country in Africa where same-sex marriage is lawful. The legislation passed with overwhelming support.

2009 – Norway and Sweden

Norway replaced its civil union laws with full marriage and adoption rights in 2009. Parliament was split over the issue.

In 2017 the Norwegian Lutheran Church, to which most Norwegians belong, voted to authorise its pastors to conduct same-sex marriage.

Sweden’s parliament passed same-sex marriage laws decisively in 2009, also replacing earlier civil union laws. The Church of Sweden allows clergy to officiate ceremonies.

Portugal legalised same-sex marriage in 2010 through a parliamentary vote. In 2016 parliament overturned a presidential veto and granted same-sex couples the right to adopt.

Iceland’s parliament unanimously passed same-sex marriage legislation in 2010. Couples were already able to adopt.

The country’s Prime Minister, Jóhanna Sigurðardóttir, was one of the first to utilise the legislation, marrying her partner, Jónína Leósdóttir.

Argentina’s parliament narrowly passed same sex-marriage laws in 2010, following several regional areas passing civil union laws.

The law sparked outcry from Catholic groups in the country as it became the first in South America to legalise same-sex marriage.

2012 – Denmark

Denmark passed same-sex marriage legislation in 2012. Couples already had the right to register as partners and adopt children.

2013 – France, Brazil, Uruguay and New Zealand

New Zealand became the first country in the Asia Pacific to legalise same-sex marriage when parliament comfortably passed the law in 2013. The law also allowed couples to adopt.

France legalised same-sex marriage and same-sex adoption in 2013, a move which attracted hundreds of thousands of protesters and counter-protesters.

Uruguay decisively passed same-sex marriage legislation in 2013. Couples already had the right to adopt.

Brazil became the first country to legalise same-sex marriage not through legislation, but with a court ruling.

The National Justice Council ruled in 2013 that civil registrars must offer same-sex marriage services, after several regions had already legislated for legalisation.  

2014 – The United Kingdom, excluding Northern Ireland

In 2013 British parliament passed a law which would legalise same-sex marriage in England and Wales the following year. In 2014 the Scottish parliament passed a similar bill.

Northern Ireland has not passed same-sex marriage legislation.

The Church of England remains opposed to same-sex marriage, despite ongoing internal debate over the issue.

The UK has performed hundreds of same-sex weddings in Australia for dual citizens.

2015 – Ireland, United States and Luxemburg

In 2015 the Supreme Court of the United States declared that the constitution protected the rights of citizens to marry, regardless of gender.

The divided Obergefell v. Hodges ruling instantly legalised same-sex marriage across all 50 states, several of which had already legislated the issue themselves.

It was the same year that Ireland became the first country to legalise same-sex marriage by popular vote.

The majority Catholic country voted in support of same-sex marriage with a majority of 62 per cent.
