The Gulf Country: Sue Neales (engl.) 160 S.

The Gulf Country is characterised by numerous turbulent wet-season rivers that pass over coastal lowlands to the Gulf of Carpentaria, but the headwaters are far distant. Beginning from the Northern Territory border there is the Nicholson River, fed by tributaries from Lawn Hill (Boodjamulla) National Park and by the Gregory River from Riversleigh World Heritage area.
The outer limits of the Gulf Country's headwaters are marked very approximately on maps by the Barkly Highway, Flinders Highway, Kennedy Developmental Road and the Peninsula Developmental Road. There are also the Wellesley and South Wellesley Islands (including Mornington and Bentinck Islands) north of Burketown.
