In the wake of the U.S. Supreme Court decision legalising nationwide marriage equality, representatives from the LGBTI lobby group visited Australia to give advice on efforts Down Under.

After meetings with several advocates, director of HRC Global Ty Cobb said Australia is well-poised to be the next country to adopt the reform.

"If you look out around the world, and where the next opportunity for the world to really move forward on marriage equality is, Australia is that place," he said.

"I think the entire international community is really focused on Australia, and the ability of the current government to listen to where Australians are on this issue."

Several polls have shown a clear majority of Australians in support of the reform, with some indicating a figure of around 70% approval. Despite this, numbers in the parliament are very close and government frontbenchers are bound to vote against the reform, meaning any bill that came forward would fail.
