The Cape Grim massacre occurred on 10 February 1828 in the north-west of Van Diemen's Land, now known as Tasmania, when four shepherds with muskets are alleged to have ambushed over 30 Tasmanian Aborigines from the Pennemukeer band from Cape Grim, killing 30 and throwing their bodies over a 60 metres (200 ft) cliff into the sea. An unknown number were reported to have escaped.
