..speak of a time, before the ending of this dimensional reality, when 
black rain will fall from the sky. In Australia, that is. This will be 
seen by traditional aboriginal as a precursor or indicator that these 
final times have arrived.  Guboo Ted Thomas, Australian Aboriginal Tribal Elder
I was in dreamtime. I seen this great wave going. I tell people about this wave. It wasn't a tidal wave. This was a spiritual wave. So, to me, I believe that the Dreamtime is going to be that.
I believe the revival is going to start in Australia when we're Dreaming. It's the hummingbee that I'm talking about. And love. We've got to learn to love one another.
You see, that's really what's going to happen to the earth. We're going to have tidal waves. We're going to have earthquakes.
That's coming because we don't consider this land as our Mother. We've taken away the balance, and we're not putting it back.

Meteor May Prove Aboriginal Legend 

A legend recounted by Aborigines speaks of a
devastating "white wave" falling out of the sky... 

In 1975, Aboriginal elders gathered in Canberra, with 350 of their people, and warned of disasters to come, followed by a time when humankind would go back to its beginnings -- with all cultures existing as one. 

At the gathering a strong message against the mining industry was formed, based on their belief that underground minerals are a vital part of the planet's energy grid and that mining is disturbing this grid. Aborigines believe that each tribe has a responsibility to take care of its own part of the world. 

One disaster recounted in Aboriginal legends, speaks of a "white wave" falling out of the sky and devastating their culture. Until now, historians had linked the legend with the arrival of white settlers but according to Professor Ted Bryant, geologist at the University of Wollongong in New South Wales, a vast tsunami would give the impression of a white wave falling out of the sky. And Bryant has found strong evidence that a tsunami struck the coast of New South Wales in the late 18th Century -- and a meteor is seen as the most likely culprit. 

Professor Bryant analyzed sediment and boulders along the coast, and says they are consistent with a tsunami hundreds of feet high, striking at a speed greater than 200 miles per hour. There is additional evidence for tsunamis hitting Lord Howe Island in the mid-Tasman Sea, along the north Queensland coast, and along the northwest coast of Western Australia. At the latter location, there is good evidence that a recent wave swept more than 20 miles inland, topping 200-foot hills more than a mile from the coast." Meteor-impact experts link the Australian tsunamis to the Taurid meteor shower, impacts from which go through peaks and troughs over the centuries. Dating of the tsunamis is broadly consistent with this cycle.
