The landscape consists of rolling terrain, rocky hills, plains, and salt-encrusted lake beds.

[3] Rainfall is higher along the southern edge of the bioregion where it transitions to the Mediterranean climate Eyre Yorke Block.

The main plant communities are spinifex grasslands, open woodlands, and chenopod shrublands.

[4] The ephemeral lakes are important breeding grounds for water birds, including silver gull (Chroicocephalus novaehollandiae), Australian pelican (Pelecanus conspicillatus), black swan (Cygnus atratus), Caspian tern (Hydroprogne caspia), red-necked avocet (Recurvirostra novaehollandiae), red-capped plover (Charadrius ruficapillus), and banded stilt (Cladorhynchus leucocephalus).

[4] Most of the bioregion, except for the salt lake beds, is used for livestock grazing, mainly sheep with some cattle.
