For Australia, it will be a long slog. The land rights acts getting through parliament that previously were making progress started to dry up about 15 years ago. IMO it was a sign Australian politics was going down the toilet.
Previous acts granted ownership of particular areas to various indigenous land councils. The councils would manage the land and it’s effectively a perpetual lease owned by the indigenous community. So post-revolution, those land rights concepts would have to come back and get expanded further to make decolonization work.
I make my own!
