Gwambygine is a small town in the Wheatbelt region of Western Australia. It is situated between the towns of York and Beverley, and is on the banks of the Avon River. One of the first known settlers was Rev. J.B. Wittenoom who was granted land in the area in 1831 and named his property Gwambygine . This property was later purchased by the state government in 1901 and sub-divided into blocks called Gwambygine Estate. Some of the land along the Avon was developed as a townsite which was gazetted in 1902.
