Turtle Island (Newcastle Bay)
Turtle Island is an island of the Torres Strait Islands archipelago, located in the Great Barrier Reef Marine Park, east of Cape York Peninsula, in Queensland, Australia.
The island is located in Newcastle Bay at the mouth of Escape River and Middle River, not far from Jackey Jackey Creek and adjacent to the Apudthama National Park. The island lies approximately southeast of Bamaga.
In the 19th century, ships were advised not to anchor to leeward of the island because it was unsafe.
