Cook Claims Eastern Australia

In April 1770, Lieutenant James Cook of the Royal Navy brought the HMS Endeavour to anchor at Botany Bay, on the southeastern coast of the Australian continent. A few weeks later, after sailing north along the coast, he took formal possession of the eastern part of the land for Britain, naming it New South Wales. The act had little immediate effect, but it laid the foundation for British colonization in 1788 and profoundly altered the lives of the Aboriginal peoples who had lived there for tens of thousands of years.

Cook had not set out to find Australia. The Endeavour sailed in 1768 on a scientific mission sponsored by the Royal Society, to observe the transit of Venus from Tahiti in 1769. Cook also carried secret Admiralty instructions to search the South Pacific for a suspected great southern continent. After Tahiti and a circuit of New Zealand, which he charted with remarkable accuracy, he turned west. Dutch navigators had already encountered the western and northern coasts of Australia in the 1600s, but the eastern coast had not been charted by Europeans.

Cook's party sighted the coast in late April 1770 and landed at a bay that he first called Stingray Bay, later renamed Botany Bay because of the many new plant specimens collected there by the naturalists Joseph Banks and Daniel Solander. The Endeavour stayed about a week. There was a brief and tense encounter with local Gweagal people, in which shots were fired, and little meaningful contact followed. Cook then sailed north, nearly losing the ship on the Great Barrier Reef in June. In August, on Possession Island in Torres Strait, he claimed the eastern coast for King George III.

The claim rested on the European doctrine that land not clearly under the control of a recognized state could be taken, a view that ignored Aboriginal ownership and custom. Cook's instructions did say to obtain native consent where possible, but no such agreement was sought. Australian law later treated the continent as unoccupied until the High Court's Mabo decision in 1992 overturned that legal fiction and recognized native title.

The consequences followed after the American Revolution closed off one destination for transported convicts. Britain chose Botany Bay's region, and the First Fleet arrived in January 1788, settling at nearby Sydney Cove instead. Colonization brought disease, dispossession and violence for Aboriginal communities. Cook himself is remembered both as a skilled navigator and mapmaker and, increasingly, as a figure whose voyage marked the start of a painful chapter, a duality that continues to shape debate in Australia today.
