The British convict settlement at Sydney Cove (Warrane) was established, initiating sustained colonial presence in Eora Country. This created new disease pathways and intensified resource pressures around Port Jackson.
Governor Arthur Phillip ordered the abduction of Arabanoo in an attempt to force communication and cultural brokerage with local Aboriginal groups. The episode illustrates coercive colonial practices amid rising tensions and precedes the 1789 epidemic’s devastation.
A sudden epidemic—commonly described in colonial records as smallpox (with some historical debate including chickenpox)—was first reported among Aboriginal people around Port Jackson. With no prior immunity, Aboriginal communities experienced catastrophic mortality and social disruption.
Arabanoo contracted the disease while assisting colonists and nursing sick Aboriginal children near the settlement hospital, and died during the epidemic. His death removed a key intermediary at a moment of profound community loss and upheaval.
Contemporary and later accounts describe extremely high Aboriginal mortality around Sydney Harbour, commonly summarized as about half the local population dying within a short period. Survivors’ dispersal and the loss of elders reshaped social and political life across Eora groups.
Phillip ordered a second abduction to obtain intermediaries after Arabanoo’s death. Bennelong (Wangal) and Colebee (Cadigal) were seized at Manly, reflecting the colony’s coercive approach as Aboriginal communities were still reeling from epidemic impacts.
Historians have continued to dispute both the precise disease agent (smallpox vs chickenpox) and how it reached Sydney, including whether it derived from colonial medical material, earlier maritime contact, or other pathways. This uncertainty shapes interpretations of responsibility and intent.
Phillip departed the colony for medical treatment and took Bennelong and Yemmerrawanne to Britain, a highly unusual episode of cross-cultural travel that occurred amid ongoing frontier violence and disease impacts in the Sydney region.
Yemmerrawanne died at Eltham while in Britain with Phillip’s party. His death underscores the vulnerability of Aboriginal visitors to new environments and illnesses, and the asymmetry of colonial power in such exchanges.
Bennelong returned to New South Wales after time in Britain, continuing to navigate and mediate relations with settlers while Aboriginal communities faced mounting land loss, violence, and the long tail of introduced diseases.
By the early 1800s, the Sydney region’s rapid settler expansion and conflict compounded epidemic damage: disrupted food access, forced movement, and crowded or marginal living conditions increased susceptibility to respiratory and other introduced infections even when smallpox was not actively epidemic.
Bennelong died at Kissing Point on the Parramatta River, marking the passing of a prominent Eora leader who had lived through the 1789 epidemic and the escalating colonial dispossession that followed.
Sydney’s early experience of epidemic disease became a repeating feature of colonial life: outbreaks disproportionately harmed marginalized communities, generated uncertainty and scapegoating, and revealed the limited will and capacity of authorities to protect Aboriginal populations.
By the 1830s, the combined effects of the 1789 smallpox catastrophe, later introduced infections, violence, and displacement had produced lasting demographic decline and profound social disruption among Aboriginal peoples of the Sydney region.
