There's growing pressure in Australia for the government to legalize gay marriage after New Zealand became the 13th country in the world to legalize same-sex marriage earlier this month. Last year, a vote on the issue in Australia's parliament failed to change the law and both political party leaders — the unmarried, atheist Prime Minister who lives with her long-term boyfriend and the staunchly Catholic opposition leader who once studied to become a priest — remain officially opposed to gay marriage. But many believe public and political pressure may have reached a tipping point on the issue in the wake of New Zealand's vote.
