AUUG have just announced that this years AUUG conference will be the last one ever:
We expect this to be the last AUUG conference, so come and have a party.
I’ve been to two of the AUUG conferences, and they are usually pretty good. Seeing this is the last one, it’s a good chance to meet and greet with people who have been involved in Unix and Linux for quite a while. The call for papers is still open till September 10, so get a paper in 
It’ll be in Melbourne, 13-14 October.
