Abstract Lichenometric dating is a cheap, relatively rapid means of dating rock surfaces, which has generally been overlooked in Australia. While lichenometry finds its greatest application in arctic and alpine geomorphological studies, there has been limited application to archaeological studies. This project set out to test the technique in south‐eastern Australia, and assess its usefulness for dating post‐settlement artefacts. The diameters of Buellia albula lichens growing on well‐dated memorials in the Bendigo cemetery were measured, and the relationship between age and lichen diameter established. The results indicate that B. albula can be used to determine the age of exposed cement surfaces from the 1890s to the present. The positive results suggest the technique should be investigated in other applications and environments in Australia, particularly where alternative dating techniques cannot be used.
