Thanks for the new thread,

As for the promotion update... it seems that the Melbourne premiere has been moved to Monday, 16 March 2009 and takes place at the Village Cinemas Jam Factory.
You can enter a competition to win premiere tickets at the premiere theater's website. Considering that this is where the premiere takes place, I would say this is fairly reliable.
If you live in Oz, you can enter the competition
