Port Jackson is the official name of what is known to the world over as Sydney Harbour.
It is a fine natural harbour, untroubled by silting as it is not the estuary of a major river, and is a safe haven for shipping no matter the weather. Its foreshores define the world’s vision of Sydney – the Sydney Opera House and Sydney Harbour Bridge are as iconic a backdrop as views of Rio de Janeiro, San Francisco and Cape Town.
Its entrance was sighted by James Cook in his voyage up that coast in 1770 and named after the Judge Advocate of the Fleet (a sort of 18th century British JAG. ) Cook didn’t dally and it was left to a minor flotilla of ships’ boats sent to discover its suitability as a harbour when the First Fleet realised that its initial landfall in Botany Bay was unsuitable for settlement. The foundation of modern Australia was founded 26 January 1788 when the British flag was raised at Sydney Cove (now Circular Quay) on its southern shore.
