Murray Darling Depression Bioregion

The Murray Darling Depression Bioregion lies in the southwest corner of NSW and extends into Vic and SA. The total area of the bioregion is 19,717,651 hectares with 40.71 per cent (8,026,167 ha) of this area in NSW and covering 10.03 per cent of the state.

The NSW portion of the bioregion is bounded in the north by the Broken Hill Complex Bioregion, with the Cobar Peneplain to the northeast and the Riverina Bioregion to the east. The Murray Darling Depression Bioregion also borders the Darling Riverine Plains to the northwest and contains outlying remnants of the Darling River and tributaries as they meet the Murray River at the Victorian border.

The bioregion lies entirely in the Western Division of NSW and contains few town centres, with Ivanhoe, just near the tip of the Riverina Bioregion, being the major settlement aside from Manilla, Emmdale and other pastoral stations in the bioregion.

The bioregion includes the Murray, Murrumbidgee, Lachlan, Darling, Barwon, Yanda River and Peacock Creek catchments.
