There has been a recent updating of the Centre for 21st Century Humanities’ website Colonial Frontier Massacres in Central and Eastern Australia 1788-1930
Take the time to read the Introduction to the website. Here the researchers explain that their criteria of a ‘massacre’ arises” from the indiscriminate killing of six or more undefended people”. Six people, they explain, from a hearth group of twenty leaves those remaining vulnerable to attack, with a diminished ability to hunt, reproduce or carry out ceremonial obligations.
It is still a work in progress, with information from Western Australia and after 1930 yet to be added.

Yes, I saw that too and have updated the relevant page on my blog. I’ve described WA massacres as I’ve come across them, but they’re not much discussed. I don’t see how we can live side by side on this land without frankly acknowledging white brutality.
I have just been considering the (probably) inevitable brutality that resulted when European colonisers invaded distant nations. You can see in the post, and in the comments, that some colonisers many have been more deadly than others, depending on when (century) the invasions took place and how urgently the locals wanted to protect their own land/families.
Thanks for the link to Colonial Frontier Massacres in Central and Eastern Australia,
