The marriage equality issue has become one of such political significance in Australia that there is no escaping the gravitational pull of the Rainbow Flag in Parliament House. The Prime Minister Julia Gillard is now the only Labor leader who hasn’t publicly declared support for gay marriage, with Queensland’s Anna Bligh, NSW’s John Robertson, Tasmania’s Lara Giddings, Victoria’s Daniel Andrews and the ACT’s Katy Gallagher who have all announced their support for legislative change.

The issue will now be taken to a conscience vote at the ALP conference coming up in December, which means that the Labor party’s official stance on gay marriage will come down to how each of party MPs feels about the topic.
