It lies to the south of the mideastern Indian Ocean features of the Wharton Basin and Perth Basin, and to the south west of the Naturaliste Plateau.

Diamantina River River flows as far as Lake Eyre. The length of the Diamantina River is approximately , and the basin is approximately , of which are used for agriculture. Most of the basin of the Diamantina is very flat—even the highest points in the northeast do not reach above sea level and Lake Eyre itself is below sea level.

The Diamantina River has no main channel, rather it is a series of wide relatively shallow channels. The major
