Rock art dating has long been used as a means of tracking early human movement across the globe, and rock art collections in the northern Kimberley region of WA are among the most prolific in the world.

Some of the Kimberley’s art is believed to be tens of thousands of years old, but this is the first time a multi-disciplinary team of scientists has set out to comprehensively study and date it.
