Quick answer
How was this voyage completed?
Endeavour left Plymouth in 1768 and entered the Pacific by way of Rio de Janeiro and Cape Horn. After observing the 1769 transit of Venus in Tahiti, Cook opened secret orders to search for a southern continent. The ship charted New Zealand and Australia's east coast, survived a Great Barrier Reef grounding and returned through disease-stricken Batavia in 1771.

Britain
The surviving expedition returns by way of the Cape
A public scientific mission concealed the second assignment
The Royal Society wanted observations of Venus crossing the Sun from Tahiti to improve astronomical calculations. Once that task ended, Cook opened Admiralty instructions to search farther south, survey and make territorial claims.
Science and imperial mapping therefore occupied consecutive pages of the same voyage orders. The first did not innocently precede an unrelated colonial use.
Tupaia's Pacific knowledge travelled with the instruments
The Raʻiātean navigator joined at Tahiti with languages, island geography and diplomatic knowledge. Around Aotearoa, he mediated encounters and made sense of a world the British did not know.
Sextants, clocks, charts and disciplined observation mattered. So did pilots, boat crews and local experts. Endeavour's route was collaborative even when later accounts centred its captain.
Reef and disease nearly consumed the expedition after its celebrated surveys
Endeavour struck the Great Barrier Reef and survived only through emergency unloading, fothering the leak and weeks of repair. Encounters at the repair site combined conflict, restraint and renewed relations with Guugu Yimithirr people.
Batavia restored the hull but exposed the crew to lethal disease. By the time the ship reached home, illness had killed more people than the reef. Precision could chart hazards; it could not remove ecological vulnerability.
Route reading
What is known—and what remains uncertain?
Reliable waypoints, disputed details and the voyage’s effects on trade, empire and local societies form separate parts of the record.
Scientific observation led directly into secret survey orders
After the Tahiti mission, Admiralty instructions sent Cook south to search, chart and claim.
European charts were not the only geography
Tupaia and coastal communities held routes, names and island relationships that shaped contact and navigation.
Disease followed the reef crisis
The grounding nearly destroyed the ship; illness at and after Batavia then killed many crew members during the final return.
Questions
Common questions
Why did Endeavour go to Tahiti?
To observe the transit of Venus in June 1769 as part of an international astronomical effort.
Did Cook sail around New Zealand?
Yes. Endeavour charted around the main islands and clarified major relationships for British maps.
Where did the ship strike a reef?
On the Great Barrier Reef in 1770. It was repaired near the present-day Endeavour River in northern Queensland.
Did British possession receive Aboriginal consent?
No evidence shows consent from east-coast communities. The possession ceremonies did not meet the consent language in Cook's instructions.
