Did a Spanish captain accidentally discover Australia while searching for the southern continent?

In short: Luís Vaz de Torres navigated the strait between Australia and New Guinea in 1606, yet he never claimed to have found the southern continent. While his expedition proved New Guinea was an island, his legacy remained buried in Spanish archives for centuries, hidden from the world until the late 1700s.

Born around 1565, likely in Galicia, Spain, Luís Vaz de Torres entered the historical record as a commander under Pedro Fernandes de Queirós. In December 1605, they departed Callao, Peru, with three ships to locate the fabled Terra Australis. By June 1606, the expedition fractured; Queirós’s flagship vanished after a mutiny, leaving Torres in command of the remaining vessels. Despite crew unrest, Torres maintained control and proceeded to explore the region, eventually navigating the 150-kilometre passage now known as the Torres Strait.

During his voyage, Torres charted the southern coast of New Guinea and made several landfalls to secure supplies, often encountering indigenous populations. Although he likely sailed close enough to see Cape York, the northern tip of Australia, he never formally identified the landmass as a continent. Instead, he noted the presence of large islands to the south. By October 1606, he had confirmed that New Guinea was not part of the massive southern landmass explorers were seeking. He eventually reached Manila in May 1607, where he and his crew vanished from official records after 1608.

Torres’s discoveries were not widely publicized. His reports and the detailed charts drawn by Don Diego de Prado were filed away in Spanish archives. It was not until the 1760s that British hydrographer Alexander Dalrymple accessed these accounts, eventually sharing the information with Joseph Banks and James Cook. The original manuscript detailing the expedition’s findings was only rediscovered in the 19th century, eventually finding a permanent home in the State Library of New South Wales in 1932, where it was finally displayed to the public in 1997.
