请问悉尼有没有遭遇洪水???

Sydney is prone to flash flooding from rain caused by East Coast Lows (a low pressure depression which can bring significant damage by heavy rain, cyclonic winds and huge swells). The most notable event was the great Sydney flood which occurred on 6 August 1986 and dumped a record 327.6 mm (12.9 in) on the city in 24 hours. This caused major traffic problems and damage in many parts of the metropolitan area. http://en.wikipedia.org/wiki/Sydney
