Shea-Oak Log is a small settlement 10km NNE of Gawler and adjacent to the Sturt Highway. Major industries in the area are manufacturing, engineering and grain/pig farming.
Until 1844 the only well defined road north of Gawler passed through Captain Bagot's pastoral property of Koonunga to the east of Kapunda. In early 1844 he defined the first road between Kapunda and Gawler which was the first copper road in South Australia. Bagot, in a bullock dray with a plough attached and leading the first convoy of ore, followed a premarked route from the mine to Gawler. Near the junction of the mine road and the Gawler to Kapunda road (the present Gawler to Greenock road) the plough broke and was substituted by the limb of a sheoak tree.
