Poeppel Corner Survey Marker, Survey marker at Queensland, Northern Territory and South Australia border intersection, Australia.
The marker stands in a remote location at 26 degrees South and 138 degrees East, defining the precise meeting point of three Australian territories.
During 1879-1880, surveyors Augustus Poeppel and Lawrence Wells established this border point through extensive measurements across challenging desert conditions.
The marker represents significant developments in Australian land surveying techniques and territorial demarcation methods from the nineteenth century colonial period.
