Australian Prime Minister Tony Abbott has been slammed by the opposition for dismissing the idea of a referendum on same-sex marriage in Australia.
The prime minister's statement comes after Ireland voted in favour of amending the constitution and introducing same-sex marriage.
Mr Abbott said 'questions of marriage are the preserve of the Commonwealth Parliament', ABC News report.
"Referendums are held in this country where there's a proposal to change the constitution," he said.
"I don't think anyone is suggesting the constitution needs to be changed in this respect."
The opposition has said Mr Abbott needs to explain why the Australian government is unwilling to hold the referendum.
"If the Irish people can vote in favour of marriage equality, the question has to be asked, what is Tony Abbott's problem with it?" opposition leader Bill Shorten said.
"Most places in the world are dealing with marriage equality, why is Tony Abbott stopping Australia becoming a more modern nation?"
Yesterday, Ireland became the first country in the world to introduce same-sex marriage by popular vote.
From coast to coast, east to west, north and south, Ireland voted with its heart for marriage equality, with six out of 10 voters - 1.2 million people - voting Yes in the referendum. The majority in favour of same-sex marriage was nearly half a million souls at 467,307.
A New Ireland has been born. That's the consensus following the victory of Yes in the referendum. Ireland has finally broken free of its dark, intolerant, baby-burying past, and has emerged blinking into the light of the gay-friendly, rainbow-hued 21st century.
It was a day when Ireland made history, becoming the first country in the world to vote in favour of same-sex marriage. And as yesterday's extraordinary events unfolded at home, the story dominated headlines across the globe as early tallies confirmed a resounding Yes vote was on the cards.
