How many times did the Japanese attack Australia?

Answer 1

Darwin was bombed by the Japanese a total of sixty times between 19 February 1942 and 12 November 1943.

The Western Australian towns of Broome and Wyndham were bombed on 3 March 1942. Over 100 people were believed to have been killed in the attack, but because Broome port was crowded with Dutch refugees fleeing the Japanese invasion of the Netherlands East Indies, exact figures are unknown. Japanese midget submarines entered Sydney Harbour on 31 May 1942. Each launched a midget submarine, hoping to sink an American heavy cruiser, the USS Chicago, which was anchored in the harbour. Nine days later, the submarine believed to be the mother ship fired at the Sydney Harbour Bridge for 4 minutes. Every shot landed well short of its target.
