Wooden post used to mark the point where the boundaries of South Australia the Northern Territory and Queensland meet.

History

Surveyor Augustus Poeppel worked for the South Australian Government as a surveyor from 1879. He placed this post where South Australia met the Northern Territory and Queensland borders in 1880. This became known as Poeppel's Corner. Unfortunately, his calculations, on the 26th parallel of latitude from the 141st to 138th meridian, were later found to be incorrect, due to an innacuracy of one inch in the chain he had used. In 1883, he rechained the line and reported this to the Surveyor General. Poeppel's Corner Post was relocated after the second survey. The post was intially donated by Geosurveys of Australia Ltd to the Art Gallery of SA and later transferred to the Historical Relics Collection.

Significance

Poeppel's Corner Post marks, quite literally, the formation of state and territorial borders in late nineteenth-century Australia. Suggestions for the division of the states and territories of Australia have varied widely throughout the history of colonisation and settlement, first reflecting the extent of exploration and surveying in charting the continent, and then political and economic change. Poeppel's Corner Post represents a wider history of surveying in Australia, and the innacuracy of the initial site of the corner is revelatory of the changes in the accuracy of scientific equipment used in surveying.
