Riverina Bioregion

The Riverina Bioregion lies in southwest NSW, extending into central-north Vic. The bioregion is approximately 9,576,964 hectares, with 7,090,008 hectares or 74.03 per cent of it lying in NSW (IBRA 5.1). The NSW portion of the bioregion occupies approximately 8.86 per cent of the State (Eardley 1999 and IBRA 5.1).

The Riverina Bioregion extends from Ivanhoe in the Murray Darling Depression Bioregion south to Bendigo, and from Narrandera in the east to Balranald in the west. Within its boundaries lie the towns of Hay, Coleambally, Deniliquin, Leeton, Mossgiel, Hillston, Booligal and Wentworth, while Griffith, Ivanhoe, Narrandera and Albury lie just outside its boundary in neighbouring bioregions.

The bioregion also includes outlying remnants of the Murray Darling Depression Bioregion in its western boundary, and the Victorian Midlands Bioregion in the south.

The Murray and Murrumbidgee Rivers and their major tributaries, the Lachlan and Goulburn Rivers, flow from the highlands in the east, westward across the Riverina plain.
