Hey there,
Check out this website:
http://www.aspect.org.au -- it's the website for Autism Spectrum Australia, but it's based in NSW and seems to be a very NSW-centric organisation.
http://www.aspect.org.au/our%20services/socialclub.aspThere is a social club for adults with AS and similar conditions which meets fortnightly in Sydney.
Hmm, looking at the PDF file linked from the above URL, it seems that there's a meeting today or tonight, in Burwood, with a guest speaker. Might be best to give the club mentor a call!
Heh, I grew up in Sydney, but I moved to Brisbane two years ago. The AS community seems a lot more vibrant up here, even though Brizzy is less than half the size of Sydney.

Good luck!

Thanks-- I've been on that site before and did ask around, but never saw the link you provided me! Anyway missed tonight's meeting, having logged on here to check for replies half an hour before the meeting started!
