Mandora Marsh

It lies at the western edge of the Great Sandy Desert bioregion and within the Mandora Station pastoral lease.

The westernmost Lake Walyarta 19°46′S 121°17′E / 19.767°S 121.283°E / -19.767; 121.283 is a claypan that extends eastwards about 30 km from the inland side of the Great Northern Highway.

Although its width may reach 5 km, the depth of water never exceeds 2 m. The eastern lake 19°47′S 121°35′E / 19.783°S 121.583°E / -19.783; 121.583 is separated from Walyarta by a calcrete ridge.

It is a broad and braided drainage line containing islands of vegetation that floods extensively but soon dries out to a series of isolated salt and claypans.

Particularly common ones include black-winged stilt, whiskered tern, grey teal, white-necked heron, and great egret.
