Primary school textbooks in 1970, eh. Mungo Lady, the first Aboriginal burial (a cremation) dated to the ice ages, was found in 1969, and would not have made it into the 1970 textbooks. 99% of research into Aboriginal prehistory has been done since 1970.
On the same principle, I guess rehctub doesn't believe in pc's, mobile phones, the internet, space shuttles, heart transplants, and all the other things discovered or invented since 1970.
You don't need a degree in archaeology to comment on Aboriginal prehistory, but you are disqualified if you base your comments on 50 yr old information, which is what would have been in a 1970 textbook.

It's quite confronting when you look at the pre-settlement AIATSIS map of Aboriginal Australia.

So if you take one area of that map, say, the landing site of the first settlement, Sydney, you find an estimated 1,500 Eora people who occupied the entire Sydney coastline including Parramatta in the west and right up to the mouth of the Hawkesbury approaching the central coast. This poses the question: why only 1,500 people occupying this magnificent coastline after the tossed about number of 40,000 years of occupation? And 70% were wiped out by smallpox (introduced) and the 'destruction of natural food sources' (not really sure what that meant in the eighteenth century). Only 1500? Considering there were 1300 on that 1788 first fleet -- and my great, great, great, (and so on) grandfather on the last conflict fleet some years later.
So I'm all for settling up. I think we should return most of the prime foreshore properties as an interim gesture, starting with Point Piper, Elizabeth Bay, Vaucluse, Double Bay etc. It would sure make those of us riddled with guilt living in our fibro homes in the western suburbs who -- like my great, great, great (whatever)grandfather, who received nothing from the invasion -- at least feel a lot better.

Its always from the sublime to the ridiculous with some isn't it?

That's and interesting analogy of the disparity between Sydney's east and Sydney's west -- I guess.
