Last month I attended a gathering of Sydney based data miners.

There are lots of parallels to IAPA (Institute of Analytics Professionals of Australia http://www.iapa.org.au/), but the audience seemed to be more hands-on analysts. Being based at Google it had quite a few web based analysts too.
The next meet-up is 11th February 2010. I'll be there having a chat and a few beers.
