Aboriginal cultures of Western Australia

Before the arrival of Europeans, the land now known as Western Australia was home to a diverse range of traditional Australian Aboriginal cultures, spread across numerous language groups, many of which remain today. The border delimiting Western Australia from South Australia and the Northern Territory was drawn by the British colonists, at the 129th meridian east, without regard to the boundaries of existing Aboriginal groups. Consequently Aboriginal cultural groupings are not limited by it; some "Western Australian" Aboriginal groups extend across the border into other states.
