From the Australian Daily Telegraph:

PRIME Minister Julia Gillard revealed yesterday that her personal stance against gay marriage was due to her conservative upbringing.

Ms Gillard said she was "on the conservative side" of the gay marriage issue "because of the way our society is and how we got here".

"I think that there are some important things from our past that need to continue to be part of our present and part of our future," she said. "If I was in a different walk of life, if I'd continued in the law and was partner of a law firm now, I would express the same view, that I think for our culture, for our heritage, the Marriage Act and marriage being between a man and a woman has a special status.
