From the Australian WordCamp Association web site:
We’re in preliminary planning for WordCamp Australia 2010. If you’re interested in helping out, please get in touch with me (Anthony Cole – me [at] anthony [dot] geek.nz ) or Dan Milward (dan [at] instinct [dot] co.nz ). We’d love to hear from you.
It looks like the event will happen in Melbourne in the first weeks of December. Nothing is official yet, and we’re looking for space for the event in addition to sponsorship and what have you, so if you’re keen, we are too.
And for those who don’t know (from WordCamp.info):
WordCamp is a 1 or 2 day conference for WordPress users and developers. The focus is on how to be a better blogger, on the development and future of WordPress, and other topics of interest.
