A number of survey parties to the Northern Territory were involved in attempts to found a settlement in the Northern Territory during the years 1864–1870. This article describes attempts by the South Australian Government to found a settlement in the Northern Territory, and the people who took part in those ventures. It includes lists of all known participants. Background In 1863, the part of New South Wales to the north of South Australia between the 129th and 138th parallels of longitude East was annexed to South Australia, by letters patent, as the "Northern Territory of South Australia", which was abbreviated to the Northern Territory (6 July 1863). The South Australian Government, with the Wakefield plan for colonisation of South Australia as a basis, believed that European settlement of the Northern Territory could be achieved in much the same way: by selling "off the plan" parcels of land to investors, and a great deal of money would go into Government coffers, which would be used for infrastructure, thus attracting further investment. All that was required was another Col. William Light, another George Gawler and a location for the new capital, which from the start was to be named "Palmerston". Finniss expedition to Adam Bay 1864 The first requirement for such a settlement was a safe harbour, and from previous explorers' experience, one stood out: Adam Bay, into which the Adelaide River flows, a river navigable for a considerable distance, where all kinds of wharfs and berths could be erected. There was little land at the mouth for buildings, but no doubt suitable areas would be found upstream. Boyle Travers Finniss, a career public servant with some surveying experience, was put in charge of a body of some 40 officers and men, and whose task it was to establish a camp at a site of his choosing and mark out some 1000 town sites and a similar number of rural sites. Finniss was not obliged to settle at Adam Bay; he chose it in preference to Port Darwin or Port Patterson on account of its harbour and the Adelaide River, which is navigable for a great distance inland, ignoring the lack of building materials, the low-lying boggy nature of the country. He chose two settlement sites; Escape Cliffs on the east coast of the bay, and The Narrows, a short distance up the Adelaide River, where there was a good landing for
