A synthesis and review of the geological evidence for palaeotsunamis along the coast of southeast Australia: The evidence, issues and potential ways forward

► Megatsunami hypothesis suggests multiple inundations in southeast Australia. ► Field evidence is used as diagnostic criteria globally; requiring evaluation. ► Multiple Holocene events have profound implications for coastal vulnerability. ► Synthesis allows simple analysis of megatsunami research. ► Inconsistencies in evidence revealed, particularly event chronology.
