THE politicians are about to debate same-sex marriage, but rugby union star David Pocock has already made up his mind.

Pocock captained the Wallabies for the first time yesterday, in a Test match against the British Barbarians at Twickenham in London. So strongly does he support the right of all people to marry, he and partner Emma Palandri have refused to seal their relationship legally until their gay friends can do the same.

Taking a stand ... David Pocock and his partner Emma Palandri.

''More than 60 per cent of Australians are in favour of same-sex marriage, so it just doesn't make sense to stop it from happening,'' Pocock says in an interview in today's Extra. ''For a lot of Christians, it's a big issue and I know there's a lot of people who don't share the same opinion as me. It comes down to equal love. I don't think it's the government's role to tell people that their love is right or wrong.''

The couple had a wedding ceremony late last year and describe themselves as married. But in solidarity with those excluded from marriage, they opted not to sign the documents confirming their union. Their stance echoes that of high-profile US actors Angelina Jolie and Brad Pitt, who said they would not marry until all US citizens were granted the same right.
