Detailed analyses of boulder deposits along 8000 km of coastal tropical Australia shows that prehistoric records of tsunami and tropical cyclone inundation can be differentiated from each other and tsunamis were larger before European settlement. The accuracy of equations used to derive these results was confirmed by the June 17 1998 tsunami event in Papua New Guinea, where flow depths of the tsunami and the size of transported clasts were surveyed, Regions that would appear safe from tsunami because of sheltering by the Great Barrier Reef or in shallow epicontinental seas such as the Gulf of Carpentaria have experienced 11 m and 3.5 m tsunami(wave height at shore) 400 yr B.P. For the Australian continent, and likely many other regions, written histories alone are too short to reasonably determine the physical vulnerability to this hazard.
