what is the new name of port jackson?

Question

it is in australia

Answer 1

As far as I know it's been Port Jackson since 1770.

The harbour's discovery by Europeans is credited to Lt James Cook in 1770, although he did not enter it. Cook named the harbour after Sir George Jackson, Judge Advocate of the Fleet at the time.

According to the Geographical Names Board of NSW, Port Jackson is "a harbour which comprises of all the waters within an imaginary line joining North Head and South Head. Within this harbour lies North Harbour, Middle Harbour and Sydney Harbour."
There are several islands within Port Jackson, including Shark Island, Clark Island, Fort Denison, Goat Island, Cockatoo Island, Spectacle Island, Snapper Island and Rodd Island. Some other former islands, including Bennelong Island, Garden Island and Berry Island, have subsequently been linked to the shore by land reclamation.

Answer 2

To the best of my knowledge, Port Jackson has always been called Port Jackson. The above contributor is right in saying most people call it Sydney harbour. Not sure who Jackson was though, must have been some early pioneer or Governor or something!

Answer 3

Port Jackson has had the same name for over 200 years. It is still Port Jackson. Most people don't call it Port Jackson these days but call it Sydney Harbour but Port Jackson is still one of its official names.
