When the City of Glenelg was first proclaimed, it extended over sections 184, 204, and 205 of the Hundred of Noarlunga, which is one of the eleven hundreds of the County of Adelaide, though by that time section 204 was already bisected west to east.
The Corporate Town of Glenelg was proclaimed on 23 August 1855 by severance from the District Council of West Torrens and District Council of Brighton. When first proclaimed, the corporate town extended over sections 184, 204 and 205 of the Hundred of Noarlunga. It is one of the eleven hundreds of the County of Adelaide stretching from Glenelg in the northwest to Port Noarlunga in the southwest; and spanning inland between the Sturt and Onkaparinga to Bridgewater in the Adelaide foothills. At the time, section 204 was already bisected west to east by the "main road leading from Adelaide to Glenelg", which ultimately was called Anzac Highway.
