In case you're not familiar with the concept (quoting from the official site),
A BarCamp is an ad-hoc gathering born from the desire for people to share and learn in an open environment. It is an intense event with discussions, demos, and interaction from participants. Here is a quote from the wikipedia description:BarCamps are a global phenomenon, regularly held in at least a dozen countries, from the US to India to New Zealand.
'BarCamp is an international network of unconferences — open, participatory workshop-events, whose content is provided by participants — focusing on early-stage web applications, and related open source technologies and social protocols.'
The UK has previously held a very successful Government-only BarCamp and, due to the nature of Canberra, many attendees of the previous Canberra BarCamp last year worked within or in areas related to government.
BarCamps are not-for-profit and cost nothing to attend.
More information is available at the official BarCamp Canberra site or at the Facebook group.
Podcasts of previous presentations are available online at http://barcampcanberra.org/blog/podcasts/
Note that I am personally on the committee coordinating the event and will be presenting on the day.
