In Australia, he obtained authorisation to build a monument for Laperouse, on a piece of land given by Sir Brisbane. He came back to France, very sad and demotivated, knowing that the British will dominate Oceania and South Pacific for generations, France arriving too late.

On 12 January 1825, Hyacinthe de Bougainville led an embassy to Vietnam with Captain Courson de la Ville-Hélio, arriving in Da Nang, with the warships Thétis and Espérance. Although they had numerous presents for the Emperor, and a 28 January 1824 letter from Louis XVIII, the ambassadors could not obtain an audience from Minh Mạng. Hyacinthe de Bougainville infiltrated Father Regéreau from the Thétis when it was anchored in Da Nang, triggering edicts of persecution against Christianity by Minh Mạng.

Bougainville visited New South Wales in 1825. That same year, he visited Port Jackson and Sydney where he set up a monument to La Pérouse and erected a grave for le Receveur in Botany Bay. He became acquainted with the leading colonial Sydney figures of the day including John Piper, Samuel Marsden, John Macarthur, and John Blaxland. The daughter of the latter, Harriot Blaxland Ritchie, became romantically involved with Bougainville.
