Boyagin Rock is located 10 km (6.2 mi) south west of Brookton and 26 km (16 mi) north west of Pingelly in the Wheatbelt region of Western Australia, which is approximately 175 km (109 mi) south east of Perth.[1][2][3] The Boyagin Rock outcrop rises 50 m (160 ft) above the surrounding land[3] and is an crestal area of a granite inselberg within the geological Yilgarn Craton framework.
It was a location that had been looked at for a water reserve, but the proposal was not proceeded with.[4] It had also been viewed as a mining location.[5] The Boyagin Nature Reserve contains Boyagin Rock, and is widely recognised as one of the few areas of intact original fauna and flora in the Avon Wheatbelt bioregion.[6] It provides refuge for a variety of fauna including numbats, goannas, echidnas and tammar wallabies.[2] The reserve was established in 1978, and covers an area of 1.21 km2.[7]
