[AUSTRALIA-QLD] Western Approaches to Torres Strait Compiled from the most Recent Surveys in the Hydrographic Office 1881.

Rare Hydrographic chart of the western approaches to Torres Strait, extending from the southern coast of New Guinea to Batavia River (now called Wenlock River) published 15th June 1881, with large corrections to August 1900 and small corrections to 1915.

Important seas such as Torres Strait were regularly surveyed by the Hydrographic Office to ensure that commanders of ships, pilots and other mariners were able to have the most to up to date information available to safely navigate foreign waters and ports as new information of changes to sea depths, sand bars, wrecks or other any other pertinent nautical information that could hinder passage became available. As updated charts were offered for sale, the earlier outdated charts in the hands of mariners, pilots, ships owners and sailors were invariably discarded, subsequently making all British Admiralty issued hydrographic charts of the period rare.
