It consists of rolling hills with thin, sandy loam soils overlaid by angular cobbles.
They are drained by a network of ephemeral streams which retain water through the dry season in small, scattered pools.
[1] The site has been identified as an Important Bird Area (IBA) by BirdLife International principally because it is home to a population of endangered Gouldian finches.
It also supports chestnut-backed buttonquails, bush stone-curlews, varied lorikeets, northern rosellas, hooded parrots, white-gaped, yellow-tinted, bar-breasted and banded honeyeaters, masked and long-tailed finches, and silver-crowned friarbirds.
[2] Other birds occasionally recorded from the IBA include the Australasian bittern, partridge pigeon, yellow-rumped munia and the northern subspecies of the crested shrike-tit.
