County of Frome

The earliest local government to be formed in the county was the Corporate Town of Port Augusta, established at Port Augusta in 1875. The adjacent Corporate Town of Davenport was established at Davenport in 1887. The District Council of Davenport was established shortly after in 1888 at Stirling North, under the provisions of the District Councils Act 1887, but was renamed Woolundunga in 1893 to avoid confusion with the adjacent corporate town. The District Council of Wilmington and District Council of Port Germein were established at Wilmington and Port Germein, respectively, by the same 1887 legislation.

In 1932, the Corporated Town of Davenport was annexed by Port Augusta. Wilmington had been renamed Hammond in 1893 but the name was restored when it absorbed much of the abolished Woolundunga in 1933. That same year, the northerly-adjacent District Council of Kanyaka, also established in 1888, occupied a small north portion of the county when it annexed part of the former Woolundunga council area in the hundreds of Woolundunga and Willochra.

In 1964 Port Augusta obtained city status and became known as the City of Port Augusta.

In 1969 Kanyaka council amalgamated with the Corporate Town of Quorn to form the new District Council of Kanyaka-Quorn. This portion of the county was transferred to the Flinders Ranges Council in 1997 when Kanyaka-Quorn was abolished bt amalgamation with the District Council of Hawker.

In 1980, Port Germein and Wilmington amalgamated to form the present District Council of Mount Remarkable which presently spans almost all of the county, with the exception of the industrial centre of Port Augusta which has remained continuously viable beside coast in the north west corner of the county.
