The Binjareb, Pindjarup or Pinjareb is the name of the Indigenous Australian group of Noongar speakers, living in the region of Southwest, Western Australia between Port Kennedy on the coast, between Rockingham and Mandurah to Australind on the Leschenault Inlet, and between a point between Byford and Armadale on the Darling Scarp, south to Benger near Brunswick Junction.
Their name is taken from the word pinjar or benjar, meaning wetlands or swamps. The Pindjarup people were "people of the wetlands", which were the main feature of the bioregion they inhabited. Many of these wetlands have now been drained, and the area has become dominated by the dairy industry, with cattle grazing on irrigated pastures.
As a people of the wetlands, the Pindjarup were famed for their fish-traps, and a seasonal cycle of six seasons, making full use of the environmental resources from the coastal estuaries and sand-dunes, through the interior lakes and wetlands to the more fertile soils of the Darling Scarp foothills and ridgelines. Western long-necked tortoises, black swans, ducks, and migratory birds formed an important part of their diet.
The lands of the Pindjarup were first explored by Europeans in 1829 when Lieutenant P. N. Preston and Dr Alexander Collie, took the British naval vessel HMS Sulphur to explore the mouths of the Peel Inlet, the Serpentine and Murray Rivers and the Leschenault Inlet.
