Ma'a Nonu wouldn't come and play in Australia. He needs to play for a New Zealand team to be eligible for the All Blacks.
If the New Zealand option doesn't work out and the NZRU can't find him some sort of other arrangement that keeps him eligible for the All Blacks, I'd guess he'll go to Europe or Japan (I believe he was already scheduled to go to Japan at the end of next year for an off season sabbatical).
