Mr Turnbull was responding to Liberal senator James Paterson's bill, which would extend religious protections to allow private businesses to refuse goods and services for gay weddings if they have "conscientious objections".
The suggested laws have been received by supporters of the "yes" vote as a "kick in the teeth" to the gay community and which would roll back the clock on anti-discrimination legislation. "If the answer is yes, then anyone who wants to turn around and say "we should pass a law that discriminates against LGBTI people" is doing the opposite of what the people have just said", he said.
And versions of this marriage equaity bill include so-called religious freedom exemptions that attack LGBT rights, reports Al Jazeera.
"That would be profoundly disrespectful and a rebuke to the people of Australia".
"We will wait to see what the final bill looks like before we give a firm commitment as to how we will vote".
"The objective of the Bill is clear: it creates equal access to marriage while protecting religious freedom in relation to marriage", he said. "I don't think their votes should mean we shouldn't have same-sex marriage, but I do think that their freedoms should be protected and I think my bill is a bill that best does that", he said.
Paterson's bill has been slammed by human rights and law bodies.
According to a Newspoll for The Australian, 63 per cent had voted Yes in the survey.
An even more draconian bill written Monday by Sen. "As a non-religious person, I should have no fewer rights to live my life consistent with my beliefs than anyone else".
The Smith bill, or the rival legislation proposed by Senator Paterson, would be subject to a series of conscience votes on both sides, requiring a majority from the collective pool of Coalition, Labor and Greens MPs. "Are we really saying, in Australia today, that you can refuse to serve someone because they're gay?"
No matter what the result is, this day is a wonderful time for all Australians who have worked hard to achieve marriage equality to come together in support.
LGBT activists also said this bill runs counter to the will of the Australian people casting a vote for equality, not a "license to discriminate".
