Margot Robbie sent a powerful message out to millions of Saturday Night Live (SNL) viewers showing her support to legalize same-sex marriage in Australia.

The 26-year-old star of Suicide Squad hosted the season premiere of SNL on 1 October.

Near the end of the show Robbie announced musical guest star The Weeknd by wearing a black t-shirt with the words ‘Say “I Do” Down Under’ and a rainbow map of Australia on it.

Although she didn’t mention the campaign or say anything about same-sex marriage, the message was clear, and seen by millions.

On twitter Robbie has been praised for wearing the shirt.

The Say I Do Down Under campaign was started by Joshua Sasse and urges Australia to legalize same-sex marriage.

On the site Sasse says: ‘Have you ever been in love? Are you in love? Could you imagine yourself there one day?’

‘Imagine too then, having your government deny you that right — what if you couldn’t marry that person. Your person.’

He also said that he was shocked to find out earlier this year that same-sex marriage in Australia was still illegal.

‘There are many hurdles to jump in order to make constitutional change, but we are now the closest we’ve ever been to that change.’

‘Let’s raise our voice and public support for change. Get a shirt. Wear your heart on your sleeve. Support Australians 4 Equality, a coalition of organisations working to deliver a winning campaign so we can legalize all love in this country and SAY “I DO” DOWN UNDER.’

Other celebrities that have joined the campaign include Sasse’s fiancé Kylie Minogue, Dolly Parton, Kelly Rippa and Scissor Sister frontman Jake Shears.
