This Saturday Perth's 3rd BarCamp will be held at Central Tafe. BarCamps are "user generated conferences — open, participatory workshop-events, whose content is provided by participants", which have a history of focusing on technology but can also be adapted to other issues.
The only other BarCamp I've attended was Bangalore BarCamp 5, and it was great. I went to sessions on social technology, community mesh networks, blogging, and low-budget films, and met a heap of fascinating people.
I haven't been to a BarCamp in Perth yet, so I've no idea what to expect, or what to contribute. Hopefully some of you will come down and bring some ideas.
UPDATE: my post about BarCamp is up over at witty title pending.
