The 'yes' campaign victory won't necessarily lift Malcolm Turnbull's stocks.
The coalition is trailing Labor in the polls by 10 points and the prime minister's personal rating has taken a big hit from the citizenship crisis.
He desperately needs a game-changer in order to claw back lost ground to Labor, shore up his leadership, and restore credibility in the coalition government and parliament as a whole.
However, while he linked himself to the campaign for same-sex marriage, the prime minister will need to spend some time salving the wounds of those hurt by the postal survey.
Labor and the Greens stated at the outset that it would give free rein to bigots and homophobes, and there was plenty of evidence to that effect over the past two months.
Children of same-sex couples felt the campaign hardest, as questions were raised about the legitimacy of their parents.
The survey itself was undermined by the fact that Turnbull opposed it initially, knowing it originated from a Tony Abbott-led meeting designed to at least frustrate, if not shelve, the issue.
While Labor leader Bill Shorten will likely let the question of the survey's origins slip into history, the opposition will keep up its refrain that Turnbull is the puppet of conservatives in the coalition and not in charge of his government's agenda.
That will come to the fore in the next three weeks as parliament debates a private senator's bill to change the marriage law.
The bill is being driven not principally by the prime minister, but a cross-party group led by West Australian Liberal senator Dean Smith.
An alternative bill being championed by conservative Liberal senator James Paterson has been rejected by Turnbull, who favours the Smith bill as the best starting point.
The prime minister has positioned himself not at the centre of the debate, but as just one vote out of 226 in the two chambers of parliament.
"Members of the coalition can vote on the bill whichever way their conscience tells them to vote and on amendments," he told reporters on Wednesday as the 61.6 per cent 'yes' vote was announced.
This will leave a leadership vacuum in what is expected to be a very messy, numbers-driven and passionate parliamentary debate.
For Turnbull, he will need strategists such as Mathias Cormann and Christopher Pyne to play their best game all season or there will be no political upside.
Labor is better positioned to benefit, with senior figures having associated themselves with the 'yes' campaign at an early stage and arguing for a direct parliamentary vote from the outset.
