Broken Bay

Broken Bay is a large inlet of the Pacific Ocean located about 50 km north of Sydney on the coast of New South Wales, Australia.

Overview

The entrance to Broken Bay lies between Barrenjoey Island at Palm Beach, and Box Head. The inlet has three arms, being the estuary of the Hawkesbury River from the west, Pittwater to the south, and Brisbane Water to the north. These three arms are flooded rivers (rias) formed when sea level was much lower than it is now.

Lion Island is located at the entrance of Broken Bay. It is so-called because it has the distinctive profile of a sitting lion. It is a nature sanctuary and has a colony of Fairy Penguins on it.

Discovery

James Cook recorded "broken land" seen, North of Port Jackson and named it Broken Bay. (just before sunset at 5 PM. 7 May 1770) However: “ The bay which the Captain named Broken Bay was not the one so called today, which lies at the mouth of the Hawkesbury River, for this was passed, unremarked, during the hours of darkness. Cook’s Broken Bay was only a few miles north of Port Jackson and near what is now known as the Narrabeen Lagoon. Matthew Flinders was the first to note the difference. Cape Three Points was about the northern head of the present Broken Bay…” [Ray Parkin "H.M.Bark Endavour" page 205] Governor Phillip was the first to examined the present day Broken Bay in a longboat from the Sirius on the 2 March 1788. Matthew Flinders placed Cook's Broken Bay at 33° 42' South. [Flinders page]

On November 28, 2005, documentary filmmaker Damien Lay claimed that the wreckage of a Japanese midget submarine, which disappeared after the attack on Sydney Harbour in 1942, was buried under sand on the seabed, just east of Lion Island. Lay claimed to have confirmed that copper wiring found at the site was consistent with that used in similar Japanese vessels.
