A passport was granted by Earl Spencer when Otto made the application, but there was a suspicion that the French Government was influenced by motives of policy lying deeper than the ostensible desire to promote discovery.
Secondly, the East India Company was concerned lest the French should establish themselves somewhere on the coast of Australia, and, with a base of operations there, menace the Company's trade.
Thirdly, Sir Joseph Banks, after conversations with Flinders and an examination of his charts, saw the importance of the work remaining to be done, and used his influence with the Admiralty to authorise a ship to be detailed for the purpose.
Thus imperial policy, trade interests and scientific ardour combined to procure the equipment of a new research expedition.

In view of the fact that the Admiralty became officially aware in June of the intentions of the French, it cannot be said that they were precipitate in making their own plans; for it was not until December 12 that they issued their orders.
The vessel allotted for the employment was a 334-ton sloop, built in the north of England for the merchant service.

She had been purchased by the Government for naval work, and, under the name of the Xenophon, had been employed in convoying merchant vessels in the Channel.

Her name was changed to the Investigator, her bottom was re-coppered, the plating being put on "two streaks higher than before," and she was equipped for a three years' voyage.

Flinders took command of her at Sheerness on January 25th, 1801.
