Nawarla Gabarnmang: Ancient Art and Human Habitation in Australia
Deep within the Australian landscape lies the Nawarla Gabarnmang rock shelter, a site of immense archaeological and cultural significance. Re-discovered on June 15, 2006, by Ray Whear and Chris Morgan of the Jawoyn Association during a helicopter flight, the site serves as a profound record of human history and artistic expression spanning tens of thousands of years.
The site's name is derived from the Jawoyn language, where nawarla means "place of" and gabarnmang means "hole in the rock." Local Jawoyn elders, Wamud Namok and Jimmy Kalarriya, provided critical cultural context, recalling visits to the shelter during their childhood and identifying the Buyhmi clan as the traditional owners of the site.
Key Facts
- Oldest Stone Axe: A ground-edge stone axe fragment dated to 35,500 years old.
- Ancient Art: Rock paintings dated to at least 28,000 years ago, the oldest firmly dated in Australia.
- Human Habitation: Evidence suggests human presence as far back as 45,180 years ago.
- Cultural Continuity: Recent paintings date as late as 1952, showing long-term use.
Archaeological Excavation and International Collaboration
The first formal excavation of the shelter took place in May 2010. This multidisciplinary effort was led by Bruno David of Monash University and featured an international team of experts, including Jean-Michel Geneste (Centre National de Prehistoire), Hugues Plisson (University of Bordeaux), Christopher Clarkson (University of Queensland), Jean-Jacques Delannoy (University of Savoie), and Fiona Petchey (University of Waikato).

Groundbreaking Tool Discoveries
One of the most significant finds during the excavation was a fragment of a ground-edge stone axe. Dated at 35,500 years old, this artifact is currently recognized as the oldest known example of its type in the world, providing vital insight into the technological capabilities of early humans.
Dating the Art and Habitation
Researchers utilized radiocarbon dating—a method used to determine the age of organic materials by measuring carbon isotopes—to establish a timeline for the site's use. The results revealed a complex history of habitation and creativity.
The ceiling art was dated using a slab of painted rock that had fallen to the floor. Ash adhering to the slab was dated to 27,631 ± 717 years cal BP (calibrated years before present), indicating the ceiling was painted before 28,000 years ago. This makes it the oldest firmly dated rock painting in Australia.
Further analysis of the stratigraphic layers (the layers of sedimentary rock and soil) provided a broader timeline:
- Lowest layer: Charcoal returned a mean age of 35,400 ± 410 years cal BP.
- Upper six layers: Deposited over the last 20,000 years.
- Base of the lowest layer: Charcoal dated to 45,180 ± 910 years cal BP, suggesting the earliest human habitation.
The possibility that the shelter was decorated from its very beginning is supported by findings at nearby locations, Malakunanja II and Nauwalabila 1. There, faceted and use-striated hematite crayons (iron oxide minerals used for pigment) were found in strata dated between 45,000 and 60,000 years old.

Recent Cultural Activity
Nawarla Gabarnmang is not merely a relic of the deep past. The site contains panels of recent paintings dated between AD 1433–1631 and AD 1658–1952. These dates align with oral reports that the cave remained a visited site within living memory.
Summary of Dating Evidence
| Feature/Artifact | Estimated Age/Date | Significance |
|---|---|---|
| Earliest Habitation (Base layer) | ~45,180 years cal BP | Oldest evidence of human presence at site |
| Ground-edge stone axe | 35,500 years old | Oldest of its type globally |
| Lowest stratigraphic layer | ~35,400 years cal BP | Early habitation period |
| Ceiling Rock Art | Before 28,000 years ago | Oldest firmly dated rock art in Australia |
| Recent Paintings | AD 1433 – 1952 | Evidence of continuous cultural use |
Frequently Asked Questions
Who are the traditional owners of Nawarla Gabarnmang?
The site is traditionally owned by the Buyhmi clan of the Jawoyn people.
What makes the stone axe found at the site special?
The ground-edge stone axe fragment is dated to 35,500 years old, making it the oldest known tool of its kind in the world.
How old is the rock art at the shelter?
The ceiling paintings are dated to at least 28,000 years ago, representing the oldest firmly dated rock art in Australia.
When was the site first inhabited by humans?
Radiocarbon dating of charcoal from the base of the lowest stratigraphic layer suggests the earliest human habitation occurred approximately 45,180 years ago.
Was the site used in recent history?
Yes, radiocarbon dating of recent paintings indicates the site was visited and decorated between AD 1433 and 1952, which is consistent with local oral histories.
