One of Australia's leading psychiatrists, Professor Kuravilla George, who is the State Government's equal opportunities champion and deputy chief psychiatrist in Victora, has joined forces with 150 doctors lobbying the Federal Government to ban same-sex marriage.
The group of doctors, who wrote in a letter to the Senate's inquiry into marriage equality, say that it was "important for the future health of our nation" to retain the definition of marriage as being between a man and woman.
"We submit the evidence is clear that children who grow up in a family with a mother and father do better in all parameters than children without," they wrote.
The news of this most recent support of discrimination comes the day after almost 7,000 people across the country simultaneously met in cities including Melbourne and Sydney, to rally for same-sex marriage and urge Prime Minister Julia Gillard to change her view on marriage equality.
Earlier this week, President Barack Obama of the United States came out in support of gay marriage, yet Prime Minister Gillard still maintains her opposition saying "I know President Obama has made that statement.
"I haven't had the opportunity to view it myself. I've seen the reports of it, but no, my view hasn't changed and when a bill comes to the parliament later this year ... I won't vote for it."
According to the Sunday Herald Sun, this news also follows Attorney-General Nicola Roxon's announcement yesterday that she would vote for gay marriage when the chance came later this year.
Initial reports indicate that the three marriage reform bills in parliament will be voted on by in July or August.
