This girl, Brittany Trubody, joined a local council a few years ago and talked them into an Astrofest. It is now Australias biggest.
She has even had a 3/4 scale copy of Discovery made (cos the full size one wouldn't go into the sports centre!).
The festival has talks by astro professionals, classes, s/h gear sales etc.
