I prefer to keep the date for Australia Day as January 26, at least at present.
We can be sorry for past wrongs, but there are many things that have come from European Settlement of Australia that are benefiting the “First Australians” now.
For example, medical assistance, support for education, dialogue which is happening now, and land rights.
I don’t think everything was perfect for the people who lived here before European Settlement, I’m aware there were inter-tribal fights, and I’m sure there were times when droughts caused some groups and tribes to be very hungry. (eg You can only fish when there is water in the rivers and watercourses).
Sometimes we’re led to believe everything was absolutely marvellous before 1770, but I would question if that is correct.
If the English had not settled here, probably the French (who were close to forming settlements), the Germans or the Dutch probably would have (or maybe the Chinese, or Indonesians).
I agree with the paragraph on P5 of the TWT Wed. 17.1.18: “Australia Day should be a day when ALL AUSTRALIANS should celebrate together … and thank those who have come before us and provided a magnificent inheritance for us all to enjoy.”
We can include the indigenous peoples in “those who have come before us and provided a magnificent inheritance for us all to enjoy” because we have much to learn from them, and would benefit from their ideas, eg land management, and many cultural ideas.
