What happened when Sydney Harbour was bombed in World War 2?
Nine days later, on 8 June 1942, I-24 surfaced off Sydney, about 10 km off Maroubra. For four minutes, the submarine’s deck gun was fired at the Sydney Harbour Bridge. Every shot landed well short of its target, with at least 10 shells hitting the residential suburbs of Rose Bay, Woollahra and Bellevue Hill. All but one of the shells failed to explode and there were no fatalities or serious injuries. (source: today.wmit.
