Researchers at the University of Newcastle are charting Colonial Frontier Massacres that were verified and recorded from 1788 to 1930.

The study currently has 250 confirmed massacres, however this number could double to 500 by the end of the investigation.

Historian Lyndall Ryan said documenting the massacres was important to determine how violent Australia’s frontier history actually was.

Ryan said that over 6000 people have been killed in massacres where government involvement was often present.
