Now, most of the Americans on the forum won't have heard of Supernova, but any Brisbane/Sydney Based ones should.
Supernova is basically a "Geek Culture" convention that has been getting bigger for the last few years. The hold one in Brisbane, and one in Sydney - though they are both practically identical. Though, admittedly, they do have a rather small artist's alley, and it is mostly reserved for Indie comics, Print comics, and Aussie Webcomic artists.
This year's guests are Aaron Douglas(Chief Tyrol from the original Battlestar Galactica), Billy Dee Williams(Lando, Hero of
The Rebellion), and Clayton and Dan Watson.
They are Pretty good cons, and somewhat Interesting things do tend to happen - Last year, at the Cocktail party, I found myself both Drunk and Sitting across a table having a conversation with Summer Glau, Whose sobriety I shan't comment on, other than it was slightly greater than mine.
So, Aussies - Are you coming?
