One person was found dead in a submerged car and 10 others were reportedly missing on Wednesday after heavy rain caused flash flooding in eastern Australia and set off a string of emergency warnings up and down the Pacific coast.

The body of the drowned 60-year-old was found early Wednesday in the state of Queensland, premier Annastacia Palaszczuk told parliament, describing the incident as a “tragedy”.

Almost half a meter of rain has fallen on some parts of her state in the last 24 hours, causing multiple road closures and transport chaos. Emergency services have received more than a 100 calls for help and swift water rescue crews have been despatched to rescue dozens of stranded residents.
