Please come and join our WordPress Meetup in Sydney. You can sign up for the group here: http://www.wpsydney.com.au/. We've recently handed over the reigns of the group to a couple of wonderful people in Sydney (as we're from Brisbane and were running a Meetup when we were down there for business). The Meetups should occur more frequently thanks to the new organisers who live in Sydney.
We'd love to have as many new members as we can and more than anything we'd love to have people volunteer to talk about WordPress and how they are using it!
Hope to see you there sometime!
