The Flinders River is the longest river in Queensland, Australia, at approximately 1,004 kilometres (624 mi). It was named in honour of the explorer Matthew Flinders. The catchment is sparsely populated and mostly undeveloped. The Flinders rises on the western slopes of the Great Dividing Range in North West Queensland and flows generally north-west through the Gulf Country, across a large, flat clay pan, before entering the Gulf of Carpentaria.

The Gulf Country or North West Queensland is the region of woodland and savanna grassland surrounding the Gulf of Carpentaria in north western Queensland and eastern Northern Territory on the north coast of Australia. The region is also called the Gulf Savannah. The Gulf Country is crossed by the Savannah Way highway.
