Fresh video of flood chaos in Australia as water swamps Brisbane 

Emergency sirens blared across Brisbane, Australia's third-largest city, on Wednesday as floodwaters that have torn a deadly path across the northeast poured into an empty downtown, swamping neighbourhoods. At least 22 people have died and more than 40 are missing across Australia's northeastern state of Queensland since drenching rains that began in November sent swollen rivers spilling over their banks, flooding an area larger than France and Germany combined.
