It means ‘research’, but it’s also a noun meaning ‘the search’. Recherché means rare, exotic, obscure.
And, of course, it’s also a reference to the exquisite Recherche Bay, way, way down in the south of Tassie.
This is a heritage listed area, saved form logging in 2003, by the wonderful Tasmanian Land Conservancy with help from Dick Smith. In 1792, the French d’Entrecasteaux expedition landed there to replenish supplies and do some … well, research.
