im a shooter from nz and ive been talking to a fullbore shooter from my club who is going to the queens in august in brisbane at belmont, and he got me interested, can anybody help me with things that i would need to know to make it to the 2009 event.

the main thing i would like to know is what rule variations are there between the two countries, i have a new rifle on the way so i will be in f open. is switch barrel allowed?
