Recherche Bay (locally /ˈri.sər/ REE-sərtch) is an oceanic embayment, part of which is listed on the National Heritage Register,[1] located on the extreme south-eastern corner of Tasmania, Australia. It was a landing place of the d’Entrecasteaux expedition to find missing explorer La Pérouse. It is named in honour of the Recherche, one of the expedition's ships. The Nuenonne name for the bay is Leillateah.[2] The bordering land is the locality of Recherche, in the local government area of Huon Valley in the South-east region of Tasmania.

Nuenonne people

The original inhabitants of the region were the Nuenonne people of Aboriginal Tasmanians. They were a maritime people who constructed durable catamarans that enabled sea journeys to places such as Bruny and the Maatsuyker Islands. The famous Nuenonne woman, Truganini, was born at Recherche Bay. The Nuenonne were either killed, died of introduced disease, or removed from the region during the early stages of British colonisation. By the mid 1830s, Indigenous habitation of Recherche Bay ceased.[3]

French exploration

French explorers set up a camp, made a garden and scientific observatory at Recherche Bay in April 1792 for 26 days, and again in January 1793 for 24 days.[4] Both landings were made to seek refuge and replenish supplies although as much time as possible was dedicated to scientific research. The botanists Jacques Labillardière, Claude Riche and Étienne Pierre Ventenat, assisted by gardener botanist Félix Delahaye, collected and catalogued almost 5000 specimens including the blue gum (Eucalyptus globulus), which later became Tasmania's floral emblem. The expedition also made friendly contact with the Tasmanian Aboriginal people there in 1793.

The scientific observatory at Recherche Bay was the site of the first deliberate scientific experiment on Australian soil. At this observatory, geoscientist Elisabeth Paul Edouard de Rossel conducted a series of measurements that proved geomagnetism varied with latitude.[5]
