Not sure if it has, but I was told on the weekend about it. I find it very odd that a player of his talent isn't wanted by any of the 5 super teams in Australia, but is wanted by an NZ super team.
He also wants to play for Fiji so he'd need to become a marquee player in Australia if and when he is capped.
I'm not sure that he couldn't find a contract in Australia, it's probably more a case that there is an opportunity at the Crusaders following the departure of Carter, Slade and Tom Taylor this year.
