Here in the elusive first state of 1826.

A second state was issued in 1839, with the chart number 1069 added.

A fourth state has corrections up to 1856.

Early 19th century Admiralty charts are inherently rare, and we can't find any record of any state of this chart having been sold at auction or through the trade.

Young John Septimus Roe (born 1797) made a rapid career in the Phillip Parker King's four expeditions of 1817-1818, 1819, 1820 and 1821-22, in the latter he lost the sight in his right eye when he fell 50 feet from the masthead onto the deck in bad weather.

"Back in Sydney, Roe carried out a survey of Sydney Harbour. Despite the capsizing of his boat on 19 August 1822, with the loss of four lives, the survey was completed, to be published by the Admiralty in 1826."

Note that the chart was made only 34 years after the arrival of the First Fleet in 1778.
