Broken Bay, a semi-mature tide-dominated drowned valley estuary,
Matthew Flinders placed Cook's 'Broken Bay' at 33° 42' South, near to the mouth of Narrabeen Lagoon.
Whatever the case, Governor Phillip was the first non-Indigenous person to examine the present day Broken Bay in a longboat from the Sirius on 2 March 1788.
Role in attack on Sydney Harbour
On 28 November 2005, documentary film-maker Damien Lay claimed that the wreckage of M-24, a Japanese midget submarine involved in the attack on Sydney Harbour in 1942 and disappeared soon afterward, 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. A few weeks later, New South Wales Planning Minister Frank Sartor announced that sonar scans conducted by the New South Wales Heritage Office at the location specified had found no trace of the lost submarine.
M-24 was eventually found approximately 13 kilometres south of Broken Bay, 5 kilometres off Bungan Head, proving the hypothesis that M-24 chose to not draw attention to its mother submarines to the south of Sydney Harbour and instead moved north towards Broken Bay.
