Arthur Phillip's description of Port Jackson shows why Sydney Cove mattered as a practical naval and colonial base. Its secure anchorage, fresh water, and ability to bring ships close to shore reduced the time needed to discharge stores. The transports could then leave for China, earn freight money, and obtain the protection of East India Company convoys on the long passage home. Replacement supplies from Britain could not be dispatched until news and ships had completed that return cycle. Nearby Dutch colonies offered limited relief because they were also operating at the end of long supply lines, so harbor efficiency directly increased the settlement's survival margin.
