This is actually a pretty interesting development.
Hunt has effectively wrote himself out of any chance of a test jumper (i would have thought). Cook Islands, though, is a different story. Unfortunately he will need to wait the three years (i think he does anyway), but there may actually be special circumstances in this case, and if he were to commit to Cook Islands for life, i would really like to see it.
First of all, he has a bona fide connection there, stronger than most relying on the GP rule. Secondly, him playing for the cook islands would be a massive publicity coo for both the cook islands and the pacific cup. Just imagine the publicity if Hunt was playing AFL and repping for the Cook Islands! Now it sounds crazy, but Hunt could qualify by playing some Local Cook islands games and trials (would be great for the game locally). At first you would say that no AFL club would let him do this, but think about it. He was only really signed mainly as a publicity stunt. Nothing would keep him in the news and raise the profile of AFl more than Hunt playing rugby league. It is a win win situation for both parties.
The only losers would be those who are going to reply to this post screaming the Credibility the credibility. But realistically, there are going to be plenty of nation hopping in the next 5 years anyway, so why not take the hit at the moment and allow Hunt to rep for cook islands, provided that he signs a commitment for life.
