Newly-out comedian and actress Magda Szubanski will add her voice to the nationwide fight for marriage equality this weekend – she’ll appear at Melbourne’s rally this Saturday May 12.

The protest’s organisers Equal Love had campaigned on Facebook for Szubanski (pictured) to join their rally, and are pleased to confirm she’s on board.

Rallies for marriage equality to be held across Australia tomorrow will celebrate US President Barack Obama’s historic support for marriage equality and increase the pressure on Australia’s political leaders to join him.

“Tomorrow’s rallies are an excellent opportunity to celebrate this important moment in the movement for marriage equality and to call on Julia Gillard and Tony Abbott to open their hearts as President Obama has done,” says Australian Marriage Equality spokesperson Rodney Croome.

Melbourne’s protest event will kick off at 1pm at the State Library, joining six other Aussie cities in a National Day of Action, also marking International Day Against Homophobia.

In Sydney on Saturday May 12, popular comedians Tom Ballard and Claire Hooper will address the marriage equality crowd outside the Town Hall.

Brisbane’s marriage equality crew will also march on Saturday, meeting at Queens Park at 1pm.

In Adelaide the Equal Love crew invite you to join them at the South Australian Parliament House, on North Terrace.

Perth will also rally for equality, meeting at Stirling Gardens – on the corner of Barrack Street and St. Georges Terrace. Comedian Hannah Gadsby is confirmed as a speaker.

Canberrans will meet at Petrie Plaza and in Hobart the hotspot will be the University of Tasmania.

“Let’s keep up the pressure!” say the Equal Love crew. Please invite every supporter of equality that you know – let’s make it big and loud so we won’t be ignored!”
