Kathy Ried has posted about some of her experience (including being a speaker) at this year's BarCampMelbourne 2008:

BarCampMelbourne2008 was, simply put, AWESOME! BarCampMelbourne2008 was held at Thoughtworks [wikipedia] at 155 Queen Street, Melbourne on 23 Feb 08, and had approximately 60 in attendance.

She talks not only about the conference itself (the male vs female attendance, the presence of Apple laptops and the age of attendees) as well as her talk on the advancement of practices at her workplace and other talks like an intro to APhpLix and how to use PHP Under Control.
