William Bower Dawes (c. 1807 – 3 August 1869) was a farmer in the colony of South Australia, and member of the first fully elected House of Assembly.
Dawes was a farmer in the Nairne district, then partner with Samuel Stocks jnr. in the district's first flour mill.[1] He was active in the Mount Barker Agricultural Society, and their president in at least one year.[2]
He was one of the councillors when the District Council of Nairne was proclaimed in 1853.[3] He served as the first Member of the House of Assembly for the seat of Onkaparinga in association with (later Sir) William Milne from March 1857.[4][5] He resigned in November 1857[6] after a series of financial reverses. He took a position as manager of a mine at Kanmantoo,[4] which he filled conscientiously, then tried mining at Karkarilla, near Moonta on Yorke Peninsula. He was later an active trader on the Stock Exchange, though without any spectacular success.[1]
