CeBIT are also hosting at least a dozen satellite conferences (including us, Drupal, Web 2, open source conf) within the exhibition and expect 35,000 visitors and 750 exhibitors. See cebit.org.au
We are looking for speakers at JoomlaDay. We cant pay local speakers on our budget, sorry, but expenses are negotiable for those coming from afar - try us! We are particularly interested in top notch technical presentations.
As an added bonus we can arrange speaking slots within CeBIT exhibition, in a theatrette on the exhibition floor. We are also running a booth. And a competition - see separate post.
Please see sydney.joomladay.org.au and fill in the form there to register your interest in presenting.
Thanks

it's gonna be a whopper!
