This chapter considers the writings of Edward John Eyre to investigate two quite different stages of the colonisation of South Australia, the frontier together with the time and space beyond the frontier, and different understandings of Aboriginal sovereignty. The Foundation Act of 1834 had established South Australia as a province. By the late 1830s, Eyre had acquired land along the Murray River and built a small house in Adelaide, the capital of the fledgling colony. When Eyre returned from his overlanding journey to the Swan River settlement in early 1840, excitement was mounting in Adelaide over the prospect of establishing a western stock route that would link the two remote townships. Hoping to salvage something from his and the expedition's dashed hopes, he decided to pursue the initial proposal to seek a route between Adelaide and King George's Sound.
