Hey there! Not many Perth people here on SS I think, but we're still a friendly bunch. There's not a huge gay scene here. There's a few events that you can find on here or more localised, on OutInPerth.com (I think that's the website).
There's also a ballroom dance class on Tuesday nights for same sex couples (although you don't have to have a partner for it). I actually am one of the teachers. If you'd like to join us, come at 7:30pm next Tuesday. Class is $15 from what I can remember (I don't handle the money at all lol). There's several beginners at the moment so don't worry about it if you haven't danced before. The advanced dancers start at 6:30pm and then come help out with the beginners to give you a variety of people to dance with in the progressives and to help out dancing with the singles.
It's loads of fun and a great way to have fun doing exercise! I think we mainly have couples at the moment from memory, and everyone is really friendly! It's at Mt Hawthorn Community Centre on the corner of Scarborough Beach Rd and (waits for google maps to load so that I can remember the street name) ahh! The Boulevard. There's a primary school neary too. If you're interested in coming, and not sure of how to get there, just let me know.
I think theres a Badminton class somewhere as well, on the same night. Not sure where though. I've never been since my time is taken up teaching the dance class.
And of course there's always me! I'm always up for a chat although the person I'm seeing is across the other side of the country

Amazing girl though!
All the best xx
