Main image

Mornington Island is the largest of the Wellesley Islands in the Gulf of Carpentaria, Queensland, and is an important centre for the local Indigenous Lardil people. The island hosts the main community settlement of Gununa and associated services.

The island is primarily a living Indigenous community rather than a tourist resort; there are opportunities to experience local art centres, fishing, and cultural programs run by community organisations. Natural features include coastal wetlands, sandy beaches and tropical gulf waters used for fishing and transport.

The Wellesley Islands including Mornington have been the traditional lands of the Lardil and other Aboriginal groups for millennia. European contact in the 19th century brought pearling, missionary activity and later administrative control.

Mornington Island lies in the southeastern Gulf of Carpentaria off the north coast of Queensland and forms part of the Shire of Mornington.

  • Access: The island is served by a small airstrip at Gununa, providing the primary regular connection to the mainland and regional centres.

What to See #

Tips for Visiting Mornington Island #
