The bombing of Darwin by the Japanese in World War 11 began in February 1942 with aircraft from four Japanese aircraft carriers, Akagi, Kaga, Hiryu and Soryu.
A National Day of Observance, known as the "Bombing of Darwin Day" is held each year on 19 February to remember those who fell during the attack.
Japanese Prime Minister Shinzo Abe was the first Japanese Prime Minister to visit Darwin in 2018, here seen laying a wreath in remembrance along with Australian Prime Minister Scott Morrison.
The first raid by 188 aircraft caused massive damage to the town and the sinking of 8 of the 45 ships in the harbour at the time.
Later the same day 54 land based bombers destroyed 20 military aircraft and inflicted further damage on the town.
While only 4 Japanese planes were shot down, 251 people were killed and around 350- 400 were wounded.
Although this was the heaviest attack, Japanese planes continued to attack the north of Australia until November 1943 with more raids on Darwin, Katherine, Adelaide River, Batchelor Airfield, Broome, Townsville and other smaller bases and towns.
The few planes available to defend Darwin were still on the ground and were destroyed easily.
Warnings from an Australian Coastwatcher on Melville Island and a Catholic Priest on Bathurst Island were thought to be mistaken sightings of a flight of US P-40E Kittyhawk fighters and ignored.
In much the same way a radar sighting was ignored at Hawaii when the Japanese bombed Pearl Harbour.
Damage from the original bombing is still visible at the hangar in Parap located behind Ross Smith Ave, which was the original Darwin Civil Airport. Now used as a museum and workshop by the Motor Vehicle Enthusiasts Club, the hangar is also an important part of the history of QANTAS Australia.
This crumbling gun emplacement at Casuarina Beach is one of the many traces of wartime activities still to be found around Darwin.
Other wartime sites include;
A memorial at Adelaide River Civil Cemetery to nine of the Post Office Staff killed in the bombing is located next to the Commonwealth War Graves Cemetery
Street names in the suburb of Alawa and Moil also remember those killed during the war.
The destroyer USS Peary was one of the ships sunk on the first bombing raid.
92 servicemen died aboard the ship during the raid.
Today a salvaged gun from the ship stands as a silent memorial, pointing towards the position where she was found after the war.
More on this Darwin bombing memorial here.
The USS Peary was a flush deck, ‘four stacked’ Clemson class destroyer, commissioned in 1920.
The remains of her wreck lie in about 27 metres in Darwin Harbour The wreck is a protected historic shipwreck under the Heritage Conservation Act.
Doctors Gully was a base for the long range Catalina Flying Boats.
With a range of 4000 km they provided an essential link during the war.
Looking across Doctors Gully towards the present day Naval Base is a much more peaceful scene today.
Darwin remains the base for surveillance of Australia's northern coastline.
