There has been a mixed reaction to Prime Minister Kevin Rudd's pledge, made during Sunday night's federal election debate, to introduce a bill to Parliament to legalise same-sex marriage within 100 days of taking office.
Gay marriage supporters say it would be an important step in Australia's history -- a change which would though, come a bit late.
"Whether it's an opportunistic thing or not it's something that we should be celebrating. It's an important step in Australia's history, but I think people would be quite disappointed to think that it's taken this long," said Equal Love convenor Ali Hogg.
ABBOTT PUTS SEATS AT RISK: GAY GROUP
Gay rights group Australian Marriage Equality (AME) says Tony Abbott should confirm a Coalition conscience vote on same-sex marriage or risk inner-city seats.
AME spokesman Rodney Croome has welcomed Rudd's commitment and Mr Abbott's acknowledgment of the issue, but says the opposition leader needs to go further.
Mr Abbott described the issue as "very important" during the debate, before reaffirming his personal opposition to same-sex marriage on Monday.
"The majority of Australians who support this reform don't expect Tony Abbott to change his mind but they do expect him to allow a conscience vote," Mr Croome told AAP.
"Kevin Rudd can't achieve this reform by himself, he needs the Coalition to also have a conscience vote if this reform is to have a fighting chance."
But the AME is taking some heart from Mr Abbott's performance. "He pointedly didn't defend the status quo," Mr Croome said.
"That gives me hope that a Coalition conscience vote is more likely than not after the election."
CHALLENGE TO ABBOTT TO MATCH ALP'S CONSCIENCE VOTE
Mr Rudd also challenged Mr Abbott to match the ALP's conscience vote. But the National Marriage Coalition, which opposes the reform, condemned the PM's promise and urged the Coalition to resist a conscience vote.
"We call upon all parties to focus on what matters most to Australians, guiding the nation always to a better future," spokesman Gerard Calilhanna said in a statement. "Our children deserve better."
Mr Croome said the Coalition would find victory in marginal inner-city seats more difficult while Mr Abbott refused to guarantee a conscience vote.
AME will leaflet seats including Brisbane, Perth, Wills and Batman, identifying which candidates support the reform.
"Going to the election with the commitment to a conscience vote would be a very smart move because it would allow inner city Liberals who support this reform ... to campaign hard on it," Mr Croome said. "At the moment they're hamstrung."
AME says polls consistently put support for the reform at 65 per cent across the country.
Mr Croome said Mr Abbott should not fear a possible conservative Senate crossbench over the issue because some in Katter's Australia Party and the Palmer United Party supported same-sex marriage.
Meanwhile, Mr Croome said there were no plans to approach Mr Abbott's openly-gay sister, Christine Forster, who has publicly disagreed with her brother's stance.
"I think she's most effective as an advocate when she does it her own way," Mr Croome said.
CHRISTIAN LOBBY SLAMS RUDD'S PLEDGE
The Australian Christian Lobby was disappointed with Rudd's announcement.
"It's very hard to understand how someone who spent years defending marriage between a man and woman now sees it as a priority to be fast tracked," said Lyle Shelton, Managing Director Australian Christian Lobby.
"It's extremely strange... he even voted against changing the definition of marriage".
"I think there should be a referendum for the Australian people to decide. This is about the fifth time this has come up, in the last two or three years. It's been rejected in the parliament, but it keeps coming back."
