Investigator set sail from
Spithead for Australia on 18 July 1801, calling at the Cape of Good Hope before crossing the Indian Ocean and sighting
Cape Leeuwin off South West Australia on 6 December 1801. The expedition put into King George Sound (Albany) for a month before beginning a
running survey of the
Great Australian Bight, which stretched to
Spencer Gulf. On 21 February 1802 a tragic accident occurred when a shore party which included Ships Master John Thistle, midshipman William Taylor and six seamen were lost when a boat capsized attempting to return to the ship at dusk in choppy waters. No bodies were recovered. Flinders named the headland
Cape Catastrophe, and the area which he had anchored
Memory Cove. Proceeding into the gulf, Flinders surveyed
Port Lincoln (which he named after his home county). Working eastwards
Investigator next charted
Kangaroo Island, Yorke Peninsula and St Vincent Gulf. On 8 April, at
Encounter Bay, a surprise meeting with under
Nicolas Baudin was cordial, the two navigators being unaware the
Treaty of Amiens had only just been signed, and both believed the two countries were still at war with one another. Sailing eastward through
Bass Strait,
Investigator visited
King Island and
Port Phillip before arriving at
Port Jackson on 9 May 1802.
Investigator spent the next ten weeks preparing and took aboard 12 new men, including an
Aboriginal person named
Bungaree with whom Flinders had previously sailed on the sloop . On 22 July
Investigator left Port Jackson, sailing north in company with the brig .
Lady Nelson sailed poorly after losing her keels and Flinders ordered her back to Port Jackson.
Investigator hugged the east coast, passed through the Great Barrier Reef and transited
Torres Strait, which Flinders had previously sailed with Captain
William Bligh on . While she was surveying the
Gulf of Carpentaria the ship's timbers were examined; the dockyard refit/conversion had failed to rectify and fix major faults with the ship, and as the voyage to Australia had revealed, she was in poor shape: the wood was rotting and there were serious extensive leaks. The ship's carpenter reported that she would not last more than six months. Flinders sailed to the Dutch settlement in
Timor hoping to find a replacement, but was unsuccessful. By now a number of the crew were unwell with numerous diseases, such as
dysentery and
scurvy, so Flinders reluctantly cut short the survey and sailed back to Port Jackson "with all possible sail, day and night" to undergo repairs. This meant abandoning his desire for a running survey on the north and west coasts of Australia. Flinders did, however, complete the circumnavigation of Australia, but not without lightening the ship by jettisoning two wrought-iron anchors. These were found and recovered in 1973 by divers at Middle Island, and lifted from the water and carried to port by the
MV Cape Don Archipelago of the Recherche,
Western Australia. The best bower anchor is on display at the
South Australian Maritime Museum while the stream anchor can be seen at the
National Museum of Australia.
Investigator reached Port Jackson on 9 June 1803 and, on her return to Sydney, Governor
Philip Gidley King requested that a survey of the vessel be carried out: Flinders left the now decommissioned
Investigator as a storeship hulk at
Port Jackson and attempted to return to England as a passenger aboard
HMS Porpoise. ==Later years (1804–1810)==
