Quajabin Peak, also known as County Peak, is a small eminence located in the western zone of the Western Australian wheatbelt, about 120 km south-east of Perth. Although not high in stature, it commands an impressive view over some of the upper catchment of the Avon River and also of the Yenyenning Lakes. The name is derived from the Nyungar language. It is not entirely clear what it means. Quaja refers to bone; and the suffix indicates either an action or belonging. It may be a bone place, like a bone, or the act of "boning" i.e. cursing.
