Croker Island is approximately one hour via light plane from Darwin and located at the meeting place of the Arafura Sea and the Timor Sea.
The island has an area of 120 square kilometres and is only 2km off the Cobourg Peninsula. The traditional owners are the Yammirr people and a permit from the Northern Land Council is required for all visitors to the island. Many Aboriginal people acknowledge Croker Island as the birthplace of the Rainbow Serpent – one of the most important spiritual beings in tales of the Dreamtime.
The island landscape is flat and covered with tropical rainforest, fringed by sandy beaches and coral reef. Birds including the brolga and jabiru are abundant and fishing is a popular draw card with anglers bringing in a range of fish such as trevally, queenfish, Spanish mackerel and mangrove jack. There is one general store on Croker Island and supplies are flown in once a week from Darwin.
