EPBC-listed Species Marine reptiles A search of the EPBC Protected matters search tool was undertaken for a buffer zone of 50 km. The results are summarised in . The EPBC Protected matters search tool lists 21 species of marine reptile as potentially occurring within the search area, this includes six species of marine turtle, 14 species of sea snake and one species of crocodile. Two of the six listed species of marine turtle have a known presence within the survey area with the flatback (Natator depressus) and green (Chelonia mydas) turtles recording nesting rookeries within the search areas (). Wildlife Online (2012) has confirmed sighting of the loggerhead (Caretta caretta), hawksbill (Eretmochelys imbricata) and olive ridley turtle (Lepidochelys olivacea). Turtle nesting is known to occur on Russell Island. The saltwater crocodile occurs within the search area, with recorded sightings in Cairns Harbour. A variety of sea snakes are likely to occur in the search area. Wildlife Online (2012) has confirmed sighting of the Dubois’ sea snake, olive sea snake, and the spectacled sea snake. Table 31.
