The Aboriginal people are much older than we believed.

Archeologists have discovered the principal confirmation to recommend that Native individuals have been in Australia for no less than 65,000 years.

The discovery indicates their arrival on the continent was up to 18,000 years earlier than previously thought.

But now, sophisticated dating of sediments at the site confirms it is one of the most significant cultural and archaeological sites in the world.

Although there is some debate, scientists have previously estimated that humans arrived in Australia between 47,000 and 60,000 years ago.

We have figured out how to build up another age for first occupation in Australia and drove it back by around 18,000 years past what was the past built up time of around 47,000 years, said Associate Prof Chris Clarkson, from the University of Queensland. 

"This has gigantic ramifications for everything from the out-of-Africa story to the eradication of megafauna and Aboriginal people groups' own insight into to what extent they have been in this nation."
