Sandy Creek, a partly perennial stream[3] that forms part of the Lachlan within the Murrumbidgee catchment in the Murray–Darling basin, is located in the Riverina region of New South Wales, Australia.

The creek’s course becomes unclear at its mouth.

[3] The Sandy Creek (technically a river[3]) rises about 19 kilometres (12 mi) east by north of the locality of Tallimba, west of the town of West Wyalong.

The creek flows generally southwest for approximately 70 kilometres (43 mi), joined by two minor tributaries, before becoming unclear approximately 5 kilometres (3.1 mi) west of the locality of Welcome Tank and northeast of Binya as it approaches Mirrool Creek (a tributary of the Lachlan River).

The Sandy Creek descends 146 metres (479 ft) over its 72-kilometre (45 mi) course.
