The British-born Babe star revealed her sexuality as part of a campaign to legalise gay marriage in her adopted Australia and she hopes her news will help raise awareness of the issue Down Under.
She tells Australian Network Ten's The Project, "I absolutely identify as gay... and it must be hard for people who don't experience it to know what the pressures of being gay are. When you are forced into this position you almost feel that you have to choose, you just want to give of yourself."
She adds in a statement, "I am 1,000 per cent in favour of gay marriage. We pay taxes, fight wars for this country, nurse you when you are sick, make you laugh, sing and dance for you, play netball for you, star in your movies, cook your meals, decorate your store windows.
"And, chances are, gay people designed whatever it is you're wearing. All Australians, including gay Australians, should have exactly the same rights, including the right to love, marry and take care of our partners."
