Two painted watercraft at the Awunbarna rock art site in Arnhem Land, northern Australia, do not match the trepang-fishing praus long associated with Macassan trade visits. Instead, their hull shapes, outrigger configurations, and fighting platforms align with Moluccan war vessels, a class of armed Indonesian craft that scholars had not previously placed on Australian shores. The finding, published in a peer-reviewed study in Historical Archaeology, suggests that Indigenous artists recorded encounters with military-style ships from the eastern Indonesian archipelago, potentially centuries before British colonization.
Why Moluccan warship imagery changes the pre-colonial contact story
For decades, the dominant narrative of pre-European contact between Australia and the Indonesian archipelago has centered on Macassan trepangers. Fishermen from Makassar in South Sulawesi sailed praus to the northern Australian coast to harvest sea cucumbers, and Aboriginal communities in Arnhem Land depicted those vessels in rock art. That record has been documented across multiple field surveys and academic volumes, forming a relatively coherent picture of seasonal, commercially focused visits.
The Awunbarna panels break with that pattern. The two painted watercraft motifs are consistent with korakora, belang, and orembai traditions, vessel types built for warfare and raiding in the Moluccan Islands of eastern Indonesia, not for commercial trepang voyages. If that identification holds, Arnhem Land artists were not only recording foreign traders but also foreign fighters. The imagery would then capture a different kind of maritime presence: one organized around military capability and the projection of power.
If Moluccan fighting craft reached the Arnhem Land coast, the scope of pre-colonial maritime contact was wider and more complex than the trepang trade alone would suggest. Armed vessels imply different motivations for voyaging, whether territorial assertion, slave raiding, coercive alliance-building, or broader political projection across the Arafura Sea. The rock art record becomes not just an artistic archive but a strategic one, preserving traces of ships whose purpose was force rather than fishing.
This possibility also reframes how scholars think about Indigenous responses to foreign arrivals. Encounters with heavily armed crews could have prompted defensive strategies, new ritual practices, or selective engagement, none of which are yet clearly visible in the archaeological record. The Awunbarna motifs hint at a more volatile frontier, where Aboriginal communities navigated overlapping networks of traders, missionaries, and warriors long before formal European colonization.
The hypothesis that comparative motif databases from Arnhem Land and the Kimberley might reveal additional korakora-style features at sites with documented Macassan activity has not yet been tested at scale. Broader surveys of boat images in northern Australian rock art, including the Kimberley region of Western Australia, confirm that contact-period ship imagery is widespread. But no published study has systematically cross-referenced those images against Moluccan vessel typologies across multiple sites. For now, the Awunbarna analysis remains a single case study rather than a demonstrated regional pattern.
How the Awunbarna motifs were identified as fighting craft
The core evidence rests on formal analysis of the two painted vessels. Researchers compared the Awunbarna motifs against known vessel types from both Macassan and Moluccan maritime traditions, examining features such as hull curvature, the placement and structure of outriggers, the presence of raised fighting platforms, and the overall proportions of the craft. The motifs differ from commonly depicted Macassan trepang praus in several structural respects, including the apparent length-to-beam ratio and the arrangement of crew spaces, and the authors concluded that the features are instead consistent with Moluccan fighting craft traditions.
Contact-period ship imagery in northwest Arnhem Land has been studied for years. Research published through the Terra Australis series on Western Arnhem Land rock art provides a broader framework for how Indigenous artists recorded foreign vessels, both European and Southeast Asian, across centuries. Within that sequence, the Awunbarna panels stand out because the vessels they depict do not fit the standard Macassan category that dominates the existing literature. Instead of low working decks optimized for processing trepang, the painted craft appear to prioritize elevated positions suitable for combat.
To strengthen their interpretation, the authors drew on ethnographic and historical descriptions of Moluccan vessels, including illustrations from Dutch colonial sources that show korakora with pronounced sterns, flared bow structures, and distinctive outrigger booms. The Awunbarna paintings echo several of these elements, even within the constraints of stylized rock art. While rock art is never a photographic record, consistent correspondences across multiple features increase the plausibility that the artists were depicting a recognizable class of ship rather than improvising generic boat shapes.
The Western Australian Museum’s maritime archaeology databases on Aboriginal watercraft depictions underline how carefully such identifications must be made. Curators there caution that boat images can be ambiguous and must be interpreted against strict comparative criteria to avoid over-attribution. That warning applies directly to Awunbarna: the case for Moluccan warships depends on the reliability of the comparative typology and on the assumption that key structural features were faithfully translated into pigment on rock.
Given these constraints, the authors frame their conclusion as a strong but testable hypothesis rather than a definitive reclassification of all non-Macassan vessels in northern Australian art. Future work could refine the typology by incorporating additional images from other sites, experimental reconstructions, and perhaps even virtual modeling of how the painted forms would perform if built as actual craft.
Gaps in dating, oral history, and archival records from the Arafura Sea
No primary radiometric dates or pigment analysis results from the Awunbarna motifs themselves have been published. All chronological placement rests on stylistic comparison with other rock art panels and with known vessel-building traditions in the Moluccas. That means the age of the paintings, and therefore the timing of any contact event they record, remains an inference rather than a measured fact. Without direct dating, it is difficult to know whether the ships arrived before, during, or after the height of Macassan trepang activity.
Indirect clues do exist. The layering of images at Awunbarna, including European-style ships and firearms in nearby panels, suggests a prolonged sequence of contact-period painting. If the Moluccan-style vessels underlie or overlie those later motifs, relative chronology might be established, but those relationships have not yet been described in detail in the published work. Microstratigraphic studies of pigment and superposition could sharpen the timeline, though such analyses require careful collaboration with Traditional Owners and adherence to cultural protocols.
Direct statements from Aboriginal custodians or community oral histories about the specific vessels depicted at Awunbarna are absent from the available record. Given that oral traditions in Arnhem Land communities have preserved detailed accounts of Macassan contact, the lack of parallel testimony about Moluccan warships is a notable gap. It may reflect the rarity of such encounters, the passage of time, or simply the fact that targeted questions about Moluccan identities have not yet been posed in community-led research settings.
On the Indonesian side, no cross-referenced archival logs of Moluccan military voyages to Arnhem Land have been identified. Dutch colonial records from the Moluccas document korakora fleets operating within the eastern Indonesian archipelago, escorting spice convoys and engaging in regional warfare, but surviving logs focus on intra-archipelagic campaigns rather than speculative expeditions across the Arafura Sea. Systematic searches of government and archival catalogues, such as those accessible through the Western Australian government’s online search portal, have yet to produce documentary confirmation of Moluccan fleets reaching Australian shores.
The absence of written records does not rule out such voyages, especially if they were opportunistic, short-lived, or conducted by actors operating outside formal colonial oversight. However, it does mean that, for now, the Awunbarna paintings stand largely alone as potential evidence of Moluccan military presence in northern Australia. Without corroborating shipwrecks, trade goods, or unambiguous historical references, the case rests on a single class of visual data.
That reliance on rock art underscores both the strength and the vulnerability of the current argument. On one hand, Indigenous artists in Arnhem Land have left an extraordinarily rich visual history of cross-cultural encounters, often capturing details that written sources ignored. On the other, images are open to multiple readings, and the temptation to match every unusual boat to an exotic origin must be resisted. The Awunbarna study advances the debate by proposing a specific, testable identification and by inviting further scrutiny rather than claiming finality.
Future research will likely move on several fronts at once: closer collaboration with Aboriginal custodians to explore oral histories and cultural meanings associated with the site; technical dating of pigments where appropriate; expanded surveys of contact-period boat imagery across Arnhem Land and the Kimberley; and renewed examination of Indonesian and Dutch records for hints of long-range military or raiding voyages. Whether or not additional evidence confirms the presence of Moluccan warships in Australian waters, the Awunbarna motifs have already succeeded in widening the conversation about who reached the continent’s northern shores, and under what terms, before the British flag was raised.
