The first circumstantial account that we have is that of Dampier; who, in his celebrated Buccaneering Voyage in the year 1688, visited that part of the North-West Coast, to which the name of Cygnet Bay has been attached:  of this place he gives a faithful and correct account, particularly with respect to its productions, and the savage and degraded state of its inhabitants:  the same navigator afterwards (in 1699) visited the West and North-west Coasts in His Majesty’s ship Roebuck, in the description of which he has not only been very minute and particular, but, as far as we could judge, exceedingly correct.

Within the last fifty years the labours of Cook, Vancouver, Bligh, D’Entrecasteaux, Flinders, and Baudin have gradually thrown a considerable light upon this extraordinary continent, for such it may be called.  Of these and other voyages that were made during the 17th and 18th centuries to various parts of its coasts, an account is given by the late Captain Flinders, in his introduction to the Investigator’s voyage; in which, and in that able and valuable work of the late Rear-Admiral Burney, A Chronological Account of Discoveries in the South Sea and Pacific Ocean, the history of its progressive discovery is amply detailed.

It was intended that the whole line of the Australian Coast should have been examined and surveyed by Captain Flinders; but the disgraceful and unwarrantable detention of this officer at the Mauritius by the French Governor, General Decaen, prevented the completion of this project.  Captain Flinders had, however, previously succeeded in making a most minute and elaborate survey of the whole extent of the South coast, between Cape Leeuwin and Bass Strait; of the East Coast, from Cape Howe to the Northumberland Islands; of the passage through Torres Strait; and of the shores of the Gulf of Carpentaria.

The French expedition, under Commodore Baudin, had in the mean time visited some few parts of the West Coast, and skirted the islands which front the North-west Coast, without landing upon, and indeed scarcely seeing, any part of the mainland.  The whole of the north, the north-west, and the western shores remained, therefore, to be explored; and in the year 1817, among the numerous voyages of survey and discovery upon which a part of the navy of Great Britain was so honourably and so usefully employed, these Coasts of Australia were not forgotten.  An expedition for the purpose of completing the survey of its North and North-west Coast was planned, under the joint direction of the Lords Commissioners of the Admiralty, and the Secretary of State for the Colonies, to the command of which I had the honour of being appointed.

The arrangements for providing me with a vessel and crew were made by the latter department; and the Governor of New South Wales was instructed to give up to my use any vessel in the colonial marine establishment that should be deemed capable of performing the service; or, in the event of there being none fit for the purpose, to purchase any suitable one that might be offered for sale.
