Loggerhead Turtle Diving in Australia
Caretta caretta
Heavier-headed and less common than the green turtle, with a nationally significant nesting population near Bundaberg.


Loggerheads are chunkier than green turtles, with a noticeably larger head and powerful jaws built for crushing molluscs, crustaceans and urchins.
The beaches around Bundaberg and the southern Great Barrier Reef support one of the most significant loggerhead nesting populations in the South Pacific, and the species is a regular sighting at Julian Rocks and Lady Elliot.
They are generally less tolerant of close approach than green turtles, so encounters tend to be shorter.
