Looks most like a Saw-shelled Turtle (Elseya latisternum) aka Myuchelys latisternum in some references, due to the short neck, relatively large head, prominent, pointed tubercles on the top and sides of its head and neck and what appears to be a large distinctive head shield, that is entire and extends in part down the parietal arch toward the tympanum. This latter feature is absent in Emydura macquarii, which is the other short-necked turtle contender in this area.
