Not sure if this is the right sub for this, but if not, please let me know where better to post.
We're taught here in Australia that Aboriginals believed in the Dreamtime / Rainbow Serpent / etc., but also that there were hundreds of different tribes around Australia with different cultures.
So my question is: Did all of these different tribes share the same origin myth, or were there major differences between them?
No, if you go to the Museum of National History in Canberra they have a great exhibit explaining some of the variation of the dreamtime myths. I visited in 2013 so I cannot re-call details I'm afraid, but although they all run along a similar theme the characters differ as do which animals formed which landscapes ect ect.
