Garden Island, located off the coast of Western Australia, is a long, narrow island with a rich history and diverse wildlife. It features a naval base and offers scenic views, though public access is limited. The island is noted for its natural heritage and is home to a tammar wallaby population. It has historical significance, with remnants of military installations from World War II, such as the Scriven and Challenger Batteries.
The island is about 10 kilometers long and 1.5 kilometers wide, with a causeway connecting it to the mainland. This connection is used for both military and civilian access. The landscape is composed primarily of limestone covered by a thin layer of sand, similar to nearby Rottnest Island.
Despite its military presence, Garden Island is recognized for its natural beauty and protected wildlife habitats. Visitors can explore the island via private boat, accessing public areas like picnic spots at Herring Bay, Pig Trough Bay, and Buchanan Bay.
