Greg Bethune has just forwarded us a PPDF which lays out on the table what he knows about the two species of Permit in Australian Waters. Greg and guide Al are sending both species to the Queensland Museum for confirmation by the curator of fishes. You can read Greg's  Permit PDF where the differences between Trachinotus anak & Trachinotus blochii is discussed. Below a (T anak) Indo Pacific Permit taken on a Seafaris
Cape York trip.
