Nick Roche in Australia??

Hi all, I was checking out Nick Roche's blog recently and he's said on it that he's going to be in Australia for 2 weeks in March. What I'm wondering is if anyone out there knows what that may be for? I've checked for the Cons around that time and the only one that's showing up is Supanova in Melbourne and Brisbane but he's not listed as a guest (as yet, anyways). Anyone know of any other Cons that are going on?
Cheers!
