Gay life in Australia...

Hi, I recently accepted that I am completely gay and after realising that i began to think about my life as a gay man (I'm currently only 15), I wanted to know (If any other gay Aussies are on here) where the most accepting cities are in Australia as i currently live in Brisbane and it isn't a very accepting city. Secondly I wanted to know when you guys think Australia will accept marriage equality because I would ideally like to get married to a man in the future. Thanks in advance for any responses.
