"Tony Abbott's attempt to block same-sex marriage by taking the ACT Government to the High Court will fail because Australians want change and are sick of his last century and discriminatory attitude," Australian Greens Leader Christine Milne said.

"Give up Tony Abbott. You are not going to thwart the will of the Australian people to end marriage discrimination.

"At some point Tony Abbott will have to admit that he supports discrimination against LGBTI people in Australia. It is wrong.

The Labor Party must commit to binding its members in support of the Greens’ efforts to protect any state or territory based marriage equality laws and federal marriage equality reform, the Australian Greens have said.

“Paul Howes’ recognition that equality should be above party politics is welcome, but it is disappointing that it arrived after Labor lost government,” the Greens’ LGBTI spokesperson, Senator Sarah Hanson-Young said.

Greens Leader Senator Christine Milne responds to anti-marriage equality ads that are being distributed around electorates:

"This kind of fear mongering is disgusting but it won't have the impact that it might've had twenty years ago. Australians have moved on. We are ready for equality and won't stand for this kind of blatant homophobia," Senator Milne said.

The Greens have a vision of a caring Australia, where every person is able to realise their highest aspirations, free from discrimination in our laws and in our minds.

That's why the Greens have always stood up for full equality for LGBTI Australians, and always will.

It was Christine Milne's Bill that decriminalised homosexuality in Tasmania in 1997, after more than a decade of campaigning and negotiating.

The Greens’ LGBTI spokesperson, Senator Sarah Hanson-Young, has today urged all Labor members to follow the Prime Minister’s example when it comes to marriage equality.

Senator Hanson-Young made the call at the launch of Australian Marriage Equality’s new website, www.vote4love.com.au, which details the way that candidates for every seat in Australia plan to vote on marriage equality.

Tony Abbott’s endless cavalcade of inappropriate comments and embarrassing missteps has continued today with a revealing insight into his opinion of the fight for LGBTI equality, the Australian Greens have said.

“People don’t fight discrimination because it’s fashionable, they do it because it’s right,” the Greens’ LGBTI spokesperson, Senator Sarah Hanson-Young said.

“The pressure of the day-to-day campaign means Tony Abbott is struggling to stay on script.

If Kevin Rudd is genuine about having marriage equality achieved he will need to work across the Parliament. All parties from across the political spectrum will have to work together to achieve marriage equality, the Australian Greens have said.

"The Greens have led the way on marriage equality and have long been ready and willing to work with all parties to achieve it," the Greens' LGBTI spokesperson, Senator Sarah Hanson-Young said.

The Australian Greens today announced their post-election plan for Australia to finally achieve marriage equality.

“I'm calling for a new bill, jointly sponsored by Labor, the Liberals and the Greens,” said the Greens’ marriage equality and human rights spokesperson Senator Sarah Hanson-Young today.

"The bill should be introduced to the new Parliament by November and voted on by Valentine's Day 2014.
