I'm probably not one to talk as I've not been to one myself, but I know a lot of people who have and they are very very happy about it.
You have a chance to meet everyone who's anyone face to face, gain contacts/friends new ideas there are seminars and fun all around...
It's a long way from OZ but if you've got the money I would say go, for sure as it is a serious opportunity + loads of fun.
