Your timeline is somewhat out regarding Bob Scott, so it slurs your other accounts.
Aka,

that Europeans considered their conquests to be a civilising influence - the contradictory proposition, of course, is that they behaved barbarically in order to achieve it.
Poirot,
Smells similar to what another major religion is practising these days. It truly is wheel going round'n round, ain't it ?
Ah, I forgot. Two wrongs make a right.

As I read these posts, I started to wonder if any of you had come across any of the very early accounts of English settlement here. Watkin Tench wrote 2 short pieces, brought together by Tim Flannery under the title "1788" (not quite correct, as the second was from around 1793).
In it he describes a few aspects of the new European settlement which bear upon some of the discussion.
Firstly, the surprise and dismay at so many Aboriginal people dying from an illness which the settlers didn't recognise, but thought might be connected to smallpox, well known in the day.Tench points out that no-one on the first fleet suffered from it, and all wondered at how the Aboriginal people had contracted it. The settlers tried some measures to prevent Aboriginal deaths, but to no avail.
Secondly, that Aborignal people quickly demanded provisions from the settlers, even though their lifestyle has been disrupted very little. Life was pretty poor in the Sydney Cove region, and Tench describes how difficult it was for Aboriginal people to find enough to eat. So government rations looked pretty good.
Thirdly, on protection. Tench notes a few Aboriginal people killed by settlers, and has no good words for the perpetrators. (When asked to lead a reprisal party, Tench successfully pleads for reduced numbers of victims, and happily gives up the job when none are found.) Proclamations are made against killing any Aboriginal people. And domestic violence among Aboriginal people was rife, with the preferred method being the husband attacking the wife's head - made more dangerous when the men bought iron axes from the settlers. Protection indeed. And I'm not surprised to read of the warfare between Aboriginal groups - by one estimate, there were 27 such wars going on when the English arrived.
