From today’s news page.
New rock art site find in Australia is a “history book”

I guess this is proof of what some of us have been saying.
It is just too close and too big for people not to know it was there.
I guess the only question I have is what happened 50 years ago to stop the pratice?

Arnhem Land, jutting into the Arafura Sea at the top of Australia, has always been a special place for Aboriginal people.
Just how special has been reinforced by the discovery of an extraordinary collection of rock art recording life in the area for the past 15,000 years, until 50 years ago.
Alongside ancient paintings of thylacines, a mammal long extinct on the mainland, are images documenting modern-day inventions - a car, a bicycle wheel, a biplane and a rifle - as well as portraits of a missionary and a sea captain.
The paintings suggest that the people of northern Australia have been interacting with seafaring visitors from Asia and Europe for hundreds, possibly thousands, of years.

The scientists surveying the paintings with the help of a local Aboriginal elder, Ronald Lamilami, say they represent possibly the longest continuous record in the world. "This seems to have been a key location where people went back again and again, adding to the art over thousands of years and many hundreds of generations," Professor Paul Tacon, an archaeologist from Griffith University in Queensland, said last week.

A good question...

How about a little blatant speculation? Perhaps the task was the ancestral custom of one particular clan or family whose last member died out?

That is as good a guess as any at this point.
“That was the responsibility of so and so’s family, and he died without an heir, so nobody ever went there again.”
It will be worth a watching to see what else they come up with.

I can guess with the best of them.
