Malcolm Turnbull (Wentworth, Liberal Party, Prime Minister) Share this | Hansard source

The commitment we took to the election was simply this: we would give all Australians their say. If they supported same-sex marriage being legalised, we would facilitate a bill, a private member's bill, coming forward into the parliament. If they did not support it, we would not. That was the commitment we took to the election, and that's what we are endeavouring to deliver. The opposition has the opportunity to vote for the plebiscite bill this week in the House. If they don't, there will be a postal vote, and every Australian will have their say.
