I heard a rumor that it will be on the N register and flown by an American crew for the time being, with the intention of putting it through the process to get it on the VH register and flown by Australian crews.
What I'm unsure about is whether an Australian crew, without FAA licenses, can do training in an N-registered aircraft in Australian airspace. Perhaps they will need FAA student pilot licenses? I'm also not sure whether those coming here to fly it with FAA licenses, need those licenses validated by CASA before carrying passengers for hire, or even just for ferrying it.
Being completely out of touch as I am with the rules in this regard, perhaps someone far more enlightened can elaborate.
