Melbourne, Sept 7 (Reuters) - Australia's High Court rejected two legal challenges on Thursday to the centre-right coalition government's proposed postal vote on whether to legalise same-sex marriage.
Australians will now begin voting in the non-compulsory ballot as early next week, with a result expected in November.
Opponents of the vote had argued the government needed the support of parliament to hold the ballot.
Recent opinion polls indicate two-thirds of Australians support same-sex marriage.
Should the public back same-sex marriage, Prime Minister Malcolm Turnbull said Australia's Marriage Act would be changed by the end of the year.
