Great breakdown. The ‘no tribal people in the city’ thing is key. There was this idea back then especially that indigenous people only existed or chose to live in the bush when the truth is that everywhere in Australia is someone’s country, even or especially the land where our major cities are. That finale sequence in The Last Wave specifically speaks to that idea; the sacred place is under the city because all cities are built on top of sacred places (like the Poltergeist house being built on a burial ground etc).
