I'm a few days late but wanted to help spread the word: the PyCon Australia 2011 conference has been officially announced, and will be held on 20th and 21st of August at the Sydney Masonic Centre. The official call for papers should open soon.
Last year's conference was the first PyCon AU, and it was a huge success; this year's going to be even bigger and better! If you're thinking about whether to attend, you might like to check out the list of presentations from PyCon AU 2010 and maybe even the videos (especially this one...).
For more info see the full announcement over at Richard's blog.
