This habitat consists of areas of exposed weather-worn pebbles on an otherwise flat or undulating plain. The pebbles are often oxidised and are dark red or black in colour. The habitat is most frequent inland, especially west of the Darling River. It is often the result of past erosion of topsoil leaving the accumulating pebbles on the surface. In wetter years these habitats can be covered in grasses, ephemeral herbs and groundcovers and may be unrecognisable (and classed as grassland). However the usual situation is that gibber is devoid, or appears devoid, of vegetation.

Typical Birds: Inland Dotterel, Banded Lapwing, Australian Pratincole, Southern Whiteface, Orange Chat, Whit-fronted Chat, Gibberbird, Cinnamon, Quailthrush, Richard's Pipit, Zebra Finch.

The habitat Bare Sand encompasses beaches, sandflats, unstabilised sand drifts (blowouts) and sand dunes with little or no vegetative cover. In near sea situations, this habitat is exposed to the sun, salt, wind and occasionally tidal influences.

Inland, this environment is equally harsh, especially in terms of exposure to heat and wind. The effects of salinity can also be found here.
