Queen snapper range extension?

Queen snapper (Nemadactylus valenciennesi) have been documented in southern Australia, from southern Western Australia to Victoria and Tasmania. However, this individual (which we believe is N. valenciennesi) had a bad start to 2013 when he/she was caught by a SETFIA member in Eden NSW, well outside its normal range (see distribution map). The fishermen who caught it had never seen one before. The fish was caught in 200m which is within the documented depth range of 40-240m. The fish is known by many names including blue morwong, sea carp and queen morwong.
