Parts of Australia‘s third-most populous city Brisbane were under water on Monday after heavy rain brought record flooding to some east coast areas and killed seven people.

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.

Residents were advised to shelter where they were unless it is unsafe to do so. Access to many areas was cut in multiple places, Queensland Fire and Emergency Services said in an alert.

Emergency crews made more than 100 swift-water rescues after receiving 8,000 calls for help in Brisbane and its surrounds since midafternoon Sunday, officials said.

All seven flood deaths have been in Queensland state, of which Brisbane is the capital. A search continues for a solo sailor, aged in his 70s, who fell overboard from his vessel in the Brisbane River near the city centre on Saturday.
