Amaraoo is a large but largely uninhabited locality in the Channel Country. Rivers like the Georgina River, Burke River, Hamilton River and Sylvester Creek flow through the locality, all of them part of the Lake Eyre basin.^[4] These rivers only flow intermittently and, even when they flow, the water usually evaporates before it reaches Lake Eyre. The land is relatively flat so there is no clear single course for these rivers but rather they flow along a series of channels in the same direction (that is, a braided river).^[5]

The waterholes that result from the flooding of these rivers sustain both native fauna and support cattle grazing which is the principal land use.^[5][6]

The Boulia Bedourie Road passes through the locality from the north-east (Wills) to the south (Bedourie). The Donohue Highway passes through the locality from the west (Toko) to the north-east (Wills)^[4]

The Tropic of Capricorn passes from east to west through the locality.^[4]

The entire locality is within the Marian Downs cattle station, which being 12,870 square kilometres (4,970 sq mi) also extends into some neighbouring localities.^[4] As at 2017, the property is the largest of 14 cattle stations owned by the North Australian Pastoral Company (NAPCO).^[7][8] The homestead is located at 23.3667°S 139.65°E / -23.3667; 139.65 (Marion Downs homestead) approx 2.7 kilometres (1.7 mi) west of the Boulia Bedourie Road.^[9]

The locality takes its name from Lake Amaroo, which in turn derives its name from the Kogai word "Amu" meaning water.^[2][3][10]

NAPCO purchased Marion Downs in 1934.^[8]

In the 2016 census, Amaroo had a population of 22 people.^[1]
