Carnac Island is a 19-hectare A-Class island nature reserve in Western Australia, located about 10 kilometers southwest of Fremantle and 3.5 kilometers north of Garden Island. Carnac Island is a Pleistocene dunes aeolianite limestone relic. In the Whadjuk Noongar language, it is known as Ngooloormayup (“place of the small brother”). The island is home to Australian sea lions, bottlenose dolphins, and a diverse array of marine bird species. Fur seals from New Zealand are regular visitors. It is famous for the amount and size of snakes, especially tiger snakes, that inhabit there. There are up to three tiger snakes for every 25 square meters on the island. As a result, very few people venture away from the shore.
