Parts of Australia's third-most populous city Brisbane were under water Monday after heavy rain brought record flooding to some east coast areas and killed eight people, AP reported. The flooding in Brisbane and its surrounds is the worst since 2011 when the city of 2.6 million people was inundated by what was described as a once-in-a-century event. All eight flood deaths have been in Queensland state, of which Brisbane is the capital. Queensland Premier Annastacia Palaszczuk said the rainfall over Brisbane had been extraordinary since November when authorities were considering water use restrictions due to a shortage.
