Australia's first gay and lesbian weddings could be annulled within a week if a high court challenge is successful.
The hastily-arranged ceremonies held under blue summer skies in Canberra were bitter-sweet occasions for some couples who realise the court could declare their marriage void on Thursday.
The government has challenged the validity of the Australian Capital Territory's fledgling law that had made gay marriage legal in Canberra and its surroundings from yesterday.
Bills to change federal law to allow gay marriage were twice rejected by parliament last year, and prime minister Tony Abbott was elected in September on a platform of opposing marriage equality.
Some same-sex marriage supporters feared that the high court would block weddings from Tuesday, when it heard the challenge. But no orders were made to halt weekend ceremonies.
If the law survives the court challenge this week, the parliament could then overturn it with legislation that would ignite a divisive and bitter debate about human and state rights.
Rodney Croome, national director of the advocacy group Australian Marriage Equality, said 25 same-sex couples had reported planning to marry in Canberra this weekend, including his deputy director Ivan Hinton. But the actual figure could be higher.
"This is the first time that we have been able to demonstrate that the sky will not cave in" due to gay couples marrying in Australia, a tearful Mr Hinton said at his wedding to Malaysian-born Chris Teoh.
Gays and lesbians who married on grassy spaces against the backdrops of Canberra's many symbols of democracy said they would be deeply disappointed if the laws failed at the first hurdle.
But several said their potentially short-lived unions would remain achievements towards marriage equality.
"Regardless of what happens on Thursday, we still get five days of legally being together," said Stacey Cowan, outside Australia's original Parliament House with her new wife, Corrina Peck.
The couple traveled more than 250 miles from their coastal home town of Blue Haven for the occasion.
Canberra resident Hayley Wilson said she was glad she did not have to go back to her homeland, New Zealand, to legally marry her Australian partner Samantha Hermes.
"The ball's definitely rolling now and hopefully it builds momentum whatever happens next week," she said.
The Australian Christian Lobby, a vocal opponent of same-sex marriage, warned that the public debate should focus on the plight of children in same-sex relationships.
Spokesman Lyle Shelton said same-sex marriage equated to children being removed from a biological parent. "We hear about equal love all the time but we don't hear about what it means for children," he said.
Gay marriage has legal recognition in 18 countries as well as 16 US states plus the District of Columbia.
