According to
Wikipedia, QantasLink operated by Sunstate Airlines serves it; is that bookable with QF miles or with oneworld miles? It also says that Virgin Australia serves it; not sure if any partner in one of the three alliances is available for redemptions.
(The page also says that TN serves it, but I think that that's out-of-date.)
Why does have to be in alliance to be reachable? Virgin Australia in general is bookable with Delta miles (though outside of any alliance), though whether to that specific destination, I don't know for sure.
