Pottery was largely unknown in Australia earlier than the recent previous, regardless of well-known pottery traditions in close by Papua New Guinea and the islands of the western Pacific. The absence of historic Indigenous pottery in Australia has lengthy puzzled researchers.
Over the previous 400 years, pottery from southeast Asia appeared throughout northern Australia, related to the actions of Makassan folks from Sulawesi (this exercise was primarily trepanging, or accumulating sea cucumbers). Older pottery in Australia is barely identified from the Torres Strait adjoining to the Papua New Guinea coast, the place just a few dozen pottery fragments have been reported, principally courting to round 1700 years in the past.
Why has no proof been discovered of early pottery use by Aboriginal folks? Various explanations have been proposed, together with suggesting that archaeologists merely weren’t wanting onerous sufficient. Well now, we’ve discovered some.
In new analysis, we report the oldest securely dated ceramics present in Australia from archaeological excavations on Jiigurru (within the Lizard Island group) on the northern Great Barrier Reef situated 600km south of Torres Strait. Our evaluation exhibits the pottery was made regionally greater than 1800 years in the past.
Finding pottery at Jiigurru
Back in 2006, a number of items of pottery had been present in Blue Lagoon on Jiigurru, 33km off mainland Cape York Peninsula.
Finding pottery at Jiigurru raised some large questions. How old was it? Was it made by native Aboriginal communities? Or was it traded in from elsewhere? If so, the place did it come from? Was it from a European shipwreck? Or was it made by the well-known Lapita individuals who colonised the islands of the southwest Pacific?
Our staff excavated a number of extra items of pottery from Blue Lagoon in 2009, 2010 and 2012.

In a primary discovery of its form, researchers have uncovered an historic Aboriginal archaeological web site preserved on the seabed
Preliminary analyses confirmed many of the pottery was produced from native supplies. However, regardless of plenty of work, our efforts to find out the age of this pottery had been inconclusive and we had been no nearer to figuring out how old it’s, or who made it.
In 2013 we went again to Jiigurru to excavate a shell midden on a headland close to the place the Blue Lagoon pottery was discovered. A shell midden represents a place the place folks lived, containing meals stays (shells, bones), charcoal from campfires, and stone instruments left behind.
Radiocarbon courting confirmed folks began tenting at this place some 4,000 years in the past, making it the oldest web site then identified at Jiigurru. But no pottery was discovered.
A broader search
By 2016 the staff had reached a useless finish in investigating the few items of pottery we had. Instead, working in partnership with Traditional Owners, we turned the analysis program to the extraordinary Indigenous historical past of the entire of Jiigurru and commenced surveying all of the islands.

In 2017 we started excavating a big shell midden at Jiigurru situated throughout the surveys.
To our amazement, round 40cm beneath the floor we started to search out items of pottery among the many shells within the excavation. We knew this was an enormous deal. We rigorously bagged each bit of pottery and mapped the place every sherd got here from, and stored digging.
The pottery stopped at about 80cm depth, with 82 items of pottery in whole. Most are very small, with a mean size of simply 18 millimetres. The pottery assemblage contains rim and neck items and a number of the pottery is embellished with pigment and incised traces.

The oldest pottery
But we had one other shock ready for us.
The deepest cultural materials was discovered almost two metres beneath the floor, in ranges we radiocarbon dated to round 6,500 years in the past. This is the earliest proof for offshore island use on the northern Great Barrier Reef.
The reef shells eaten and discarded in these lowest ranges had been buried so shortly that they nonetheless have color on their surfaces. Archaeological websites of this depth and age are unusual wherever across the Australian coast.
Radiocarbon courting of charcoal and shells discovered near the pottery exhibits that it’s between 2,950 and 1,815 years old, making it the earliest securely dated pottery ever present in Australia. Analysis of the clays and tempers exhibits that the entire pottery was seemingly made on Jiigurru.

What does it inform us that we didn’t already know?
The findings are clear proof that Aboriginal folks made and used pottery hundreds of years in the past.
The archaeological proof doesn’t level to outsiders bringing pottery on to Jiigurru. Instead, the proof exhibits that Cape York First Nations communities had been intimately engaged in historic maritime networks, connecting them with peoples, knowledges and applied sciences throughout the Coral Sea area, together with the data of the best way to make pottery.

They weren’t remoted or geographically constrained, as as soon as conceived.
The outcomes additionally show that Aboriginal communities had refined watercraft and navigational abilities in utilizing their Sea Country estates greater than 6,000 years in the past.

What else don’t we all know?
The Jiigurru pottery offers us new perception into Australia’s historical past and the worldwide attain of First Nations communities hundreds of years earlier than British invasion in 1788.
Very little analysis has been carried out wherever on japanese Cape York Peninsula. We suppose it is vitally unlikely that Jiigurru holds the one secrets and techniques to our nation’s peopled previous. What different cultural and historic surprises await to be discovered?
