Haha oh dear. You know I used to have the same problem? Still do. I guess if you hear of LGBT events, such as mardi gras, protests, groups, i dunno, go to them. Just go to random places, like suburbs around you. that's what I did. Australia seems to be seriously lacking in places for the LGBT community to hang out.
Using the internet is popular. There are a few like, dating site things out there i think. My friend went on a website called pink couch or something, but i think she had to pay, so she couldnt be bothered
You could even meet people here on kitten board i guess. We are probably the most 'like-minded', all here for the same reason...mostly.
Dont worry, there are plenty of single teens out here in Australia looking for the exact same thing as you are, like me for example. Not that that's a come on or anything, cos it totally isn't

I can just relate to you
Good luck with your endeavours! Hope this helped a bit
