Bigge Island have been a sacred island for the aborigines for more than 20,000 years.Well-preserved Aboriginal paintings grace the walls of caves, depicting mythical figures and evidence of the European entrance into the Aboriginal way of life. Warabis, or rock wallaby (the smallest of the wallabies), are numerous on this island and often can be seen sprinting from one rock ledge to another. Near this island lies the Low Rocks atoll which is the home for four species of terns, pied comorants, white-bellied sea eagles, and osprey. The island is also a nesting site for green and flatback turtles, and has its own resident crocodile, which is often seen patrolling the waters around the island.
