In December 1829, Mount Barker was named after Captain Collet Barker, commandant of the garrison at King George Sound, by naval ship's surgeon Thomas Braidwood Wilson. Wilson explored the area in company with the Noongar Mokare from King George Sound, John Kent (officer in charge of the Commissariat at Frederick Town, King George Sound), two convicts and Private William Gough of the 39th Regiment, while his ship the Governor Phillip was being repaired.
