The present-day Transdev John Holland route 324 follows the route of the former tram line as far as the point where the tramway turned off Old South Head Road into Gap Park. The bus and tram routes meet again near the terminus in Military Road. Sydney Harbour defences during WWII In 1942, during World War II, the Sydney Harbour anti-submarine boom net was constructed on Georges Head and was designed to prevent enemy submarines from entering into Sydney Harbour. The boom net spanned the entire width of Port Jackson and a boom net winch house was located on Liangs Point, Watsons Bay. On the night of 31 May 1942, three Japanese midget submarines attempted to enter Sydney Harbour in what became known as the attack on Sydney Harbour. One of the Japanese midget submarines became entangled in the boom net; and, after unsuccessful attempts to free the submarine, the crew detonated charges within the sub, killing themselves and destroying their sub in the process. During this period, Nielsen Park was used as an anti-aircraft base. The base had its own interim wooden barracks, searchlights and anti-aircraft guns. In Gap Park, a gun emplacement for a small calibre gun, which was never installed was also intended for use during World War II. Christina Stead The novelist Christina Stead lived in 14 Pacific Street from 1911 to 1928, after which she went overseas. The house is marked with a plaque mounted in the footpath. Stead was the first writer chosen for the Woollahra Council Plaque Scheme, which was inaugurated in 2014. The house, known as Boongarre or Boongaree was built in the 1870s. It was owned by the Stead family from 1918 to 1980 and is sometimes known as Stead House. It was later acquired by the soccer player Mark Schwarzer. In 2011, Woollahra Council voted to confirm the heritage status of the house. It is now listed on the council's heritage list. Population At the 2021 census, 883 people were recorded in Watsons Bay.
