Sydney Origin: The Early Days of Port Jackson

Port Jackson was discovered by Captain James Cook in 1770, during his famous voyage to Australia. Cook was exploring the eastern coast of the continent when he sailed into the harbor, which he named after Sir George Jackson, a member of the British Admiralty.
For the next several years, the area around Port Jackson was used as a penal colony by the British government. The first European settlement in the area was established in 1788, and it was named Sydney Cove, after the British Home Secretary at the time, Thomas Townshend, Lord Sydney.
The Growth of Sydney

Over the next few decades, Sydney grew rapidly. It became an important center for trade and commerce, and it played a key role in the development of Australia as a nation. By the mid-19th century, Sydney was the largest city in Australia, and it was one of the most important cities in the British Empire.
During this time, the name “Sydney” became synonymous with the city itself. People began using the name to refer to the entire area around Port Jackson, rather than just the original settlement at Sydney Cove. Eventually, the name “Port Jackson” fell out of use, and the city became known simply as Sydney.
Conclusion

So, to answer the question “When did Port Jackson become Sydney?” – the answer is that it happened gradually, over the course of several decades. As the city grew and became more important, the name “Sydney” became more and more closely associated with the area around Port Jackson. Today, the name “Sydney” is known around the world as a symbol of Australia and its rich history.
