Percy Isles to Whitsunday Island, 1803-1951

Percy Isles to Whitsunday Island, 1803-1951. This map published by the Admiralty in 1951 shows the accumulation of surveys and the origin of the coastal charts. Information is taken from a joint Admiralty & Colonial Survey 1873-79, with additions from Captains Flinders, King, Blackwood, Owen Stanley, Yule, Dayman, Denham, Nares and Maclear 1803-81, Edgell, Bennett and Henderson 1926-29, and RAAF aerial reconnaissance 1926. Corrections were made in 1945, 1946, 1947, 1948 and 1951. A note on the map states 'The delimitation of the outer edge of the Barrier Reef has not been satisfactorily established'.
