In the middle of the West Australian coast, 1,100 km North of Perth, lies the small town of Exmouth. It was built in 1967 primarily as a communications base for the US marines, who left in the early 1990s. Part of the base has been used by the Australian marines, the other section has been converted into accommodation. Exmouth is first and foremost the starting point for tours to Ningaloo Reef Marine Park, the largest coral reef in Western Australia. From November to March visitors can see the turtles that come to the beach to lay their eggs. A special highlight for visitors is being able to dive with the largest fish in the world, the whale shark, at the fantastic Ningaloo Reef.
