On 19 February 1942 Japanese bombs fell on mainland Australia for the first time. The port and city of Darwin suffered two devastating attacks by over 188 Japanese aircraft that day.
Over the next twenty months northern Australia was to endure almost a hundred air raids, from Exmouth in the west to Townsville in the east. At the same time, Japanese submarines attacked merchant vessels off the coast of eastern Australia.
Here’s a bit more about the attacks:
Here’s a clear breakdown:
Types of Attacks on Australia
Japan carried out several forms of attack against the Australian mainland, offshore islands, and northern approaches:
- Air raids
- The most significant campaign was the bombing of Darwin (19 February 1942), when 188 aircraft attacked in two waves. This was the largest ever foreign attack on Australia, killing around 240 people.
- Darwin was bombed over 60 more times between 1942-43.
- Other towns attacked included Broome, Wyndham, Derby, Katherine, Townsville, Port Hedland, and Horn Island.
- Broome (3 March 1942) saw one of the worst air raids after Darwin, with dozens killed and many flying boats destroyed.
- Naval bombardments
- In 1942, Japanese submarines shelled Sydney and Newcastle, firing on industrial and port facilities. Damage was light and casualties few.
- Submarines also laid mines off the Australian coast.
- Submarine attacks
- May–June 1942: Midget submarines penetrated Sydney Harbour. They sank the depot ship HMAS Kuttabul, killing 21 sailors.
- Japanese long-range submarines also attacked merchant shipping off Australia’s east coast and in the Torres Strait.
Impact of the Attacks
- The raids caused destruction, loss of life, and widespread alarm.
- The Darwin raids in particular exposed how vulnerable northern Australia was, leading to the evacuation of civilians and strengthening of Allied defences.
- Japanese submarine activity sank dozens of merchant ships around Australian waters, disrupting supplies.
- However, the damage to industry and military capability was relatively limited compared to bombing campaigns in Europe or Asia.
Was Australia Seriously Threatened by Invasion?
- Invasion was considered but rejected by Japan.
- After early victories in Southeast Asia, some Japanese planners proposed invading northern Australia.
- The Imperial Japanese Navy favoured it, but the Army opposed it, arguing Japan lacked the manpower and resources to occupy such a large, sparsely populated continent while also fighting in China, the Pacific islands, and Southeast Asia.
- Instead, Japan adopted the “isolation” strategy: cutting Australia off from the United States by seizing New Guinea, the Solomons, and other islands. This led to the battles of the Coral Sea, Kokoda Track, and Guadalcanal.
So ,while attacks on Australia were real and deadly, a full-scale invasion was never realistically attempted or logistically feasible. Japan aimed to neutralize Australia’s role as a U.S. base, not conquer it outright.
