We report on early occupation from the Parnkupirti site on Salt Pan Creek at Lake Gregory, on the edge of the Great Sandy Desert of northwest Australia. OSL ages from excavations, and stratigraphic correlations between dated exposures along Salt Pan Creek, show some stone artefacts in situ in sediments dating from greater than 37ka and most probably on stratigraphic grounds in the range of ~50–45ka. The deep stratigraphic section at Parnkupirti also provides a long record of the Quaternary history of Lake Gregory, which remained a freshwater system during the Late Quaternary.
