Where is it? In Capricornia Cays National Park, on the outer southern Great Barrier Reef, Qld.
Next time you’re stressed out and having a shipwreck fantasy, think of Lady Mugrave Island. Entirely uninhabited and accessible only by launch from 1770, the coral cay offers limited camp sites (bring your own fresh water and food). The island has an 8km circumference and is surrounded by 1192 hectares of reef. Clear waters give spectacular views of the vibrant reef, while coral trout and turtles are likely to swim beside you. Between November and February green turtles nest on the beach, which is closed between February and March to protect the hatchlings.
