The remote site in Arnhem Land where the fragment of charcoal rock art, dated to 28,000 years ago, was found is also home to 1000-year-old art on the ceiling of a rock shelter.
A team led by Bruno David from Monash University has found and firmly dated a fragment of charcoal rock art to 28,000 years ago.
This makes it the oldest painting so far proven by carbon-dating in Australia and among some of the earliest evidence of human painting.
The discovery was made last June but has been dated only recently by experts from New Zealand's University of Waikato radiocarbon laboratory.
The piece was discovered by Bryce Barker from the University of Southern Queensland. "The discovery shows Australian Aboriginal people were responsible for some of the earliest examples of rock art on the planet," Professor Barker said.
France's Chauvet caves were carbon dated to 35,000 years ago. They were known as the world's oldest confirmed rock art sites until last week, when drawings in Spain's El Castillo caves were dated to 40,800 years.
The Bradshaw figurative paintings found throughout the Kimberley are well known internationally, Professor Barker said. "The Bradshaws are often talked about as being the oldest rock art in Australia but the oldest firm date for them is 16,000-17,000 years taken from a wasp nest covering the art."
