Poeppel Corner is about 174 km west of Birdsville, in the middle of the Simpson Desert.
Augustus Poeppel, after whom the point is named, conducted a survey in the mid-1880s to find the exact location of the central Australian colonial borders.
Originally the point was located in a salt lake, but it was found that the measuring chain used was a few centimetres too long.
Another survey was conducted by Lawrence Wells, who relocated the post to its current position.
The Poeppel Corner Survey Marker is a heritage-listed site, having been added to the Queensland Heritage Register in 2012.
