I have recently just starting the Adelaide Poker Meetup (APM): http://poker.meetup.com/1200/ it is a great medium for bringing poker enthusiastis from around Adelaide together to do everything to do with poker.
There is going to be a $10/yr membership fee to cover the costs of running the website as well as promotion etc to attract new players. Our first meetup will be in early March, so get on over to the website and sign up to be a member. The website features include message boards, file and photo sharing, calender and email updates.
Hope to see you there!
Update August 2009: I discontinued this meetup some time ago. If you want to set one up for yourself, check out the Adelaide Poker Meetup Waiting List for a list of interested people.
