Mornington Island is located about 125kms north-west of Burketown, 200kms west of Karumba, and 444kms from Mt Isa. Mornington Shire incorporates twenty-one of the twenty-two islands and has an area of 1,248.4 square kilometers.
The Wellesley Islands are remnants of the mainland now submerged by the syncline that formed the Gulf of Carpentaria and are essentially flat platforms with little relief. There are substantial areas of intertidal flats and fringing reefs associated with most Islands. After the end of the Ice Age, approximately 6,500 years ago, rising sea levels reached their current height. Before this change, the Wellesley Islands formed a peninsula that was part of the Carpentaria mainland.
