Australian fashion magazine Marie Claire has gone all-out to support the local push for marriage equality.

Featuring numerous celebs wearing the rainbow-coloured “I Do” pro-same-sex marriage theme, the magazine’s July issue shows covergirl Rachael Taylor, who says: “I think Australians are big-hearted and open-minding people, and embracing same-sec marriage is just a logical extension of who we are.

“I can’t wait to celebrate the weddings of ALL my friends in the coming years. It’s time.”

Among the dozens of other well-known stars of stage, screen, music, sporting and public life involved are: Alex Perry, Bob Brown, Charlotte Dawson, Brian McFadden, David Pocock, Delta Goodrem, Jennifer Hawkins, Magda Szubanski, Matt Mitcham, Megan Gale, Mel B, Missy Higgins, Rachel Griffiths, Ruby Rose and Sophie Lowe. See all of them here.

The campaign has been produced in partnership with the GetUp! lobby group – sign its petition here.

Marie Claire editor Jackie Frank says it’s time for the nation to get behind this issue and she’s glad the magazine can help.

“When I got married more than 15 years ago, I was able to declare my love for my husband in front of my friends and family, and have it recognised under Australian law,” she points out. “It angers me that this basic human right is not open to all Australians.

“We live in the last developed, English-speaking country in the world whose leader hasn’t expressed support for marriage equality. The last one.

“The time for change is now. We’re imploring all MPs to vote in favour of marriage equality when bills to amend the Marriage Act go before parliament soon, and we’ve enlisted some prominent Australians to help us.”

Special “I Do” campaign launch events to be broadcast on 7’s Sunrise breakfast show will happen in Sydney’s Martin Place and Melbourne’s Bourke Street Mall from 6-9am this Thursday June 7.

This is not Marie Claire magazine’s first campaign for social reform. For eight years until it was enshrined in law in 2009, the mag pushed hard on the issue of paid maternity leave.
