A wall of water rushed through the Australian city of Toowoomba yesterday, claiming the lives of at least eight people.
The latest estimate of those missing and unaccounted for is 72.
The raging torrent of muddy water picked up cars and tossed them like toys, carried away furniture as it washed through stores and prompted scores of emergency calls as it swamped Toowoomba, a city of about 90,000, 100km west of Brisbane.
A major search and rescue effort is under way with dozens of people waiting for help after flash flooding hit a number of communities west of Brisbane.
Parts of the city of Toowoomba were devastated by tsunami-like flash flooding, which has also left a trail of destruction in the Lockyer Valley at the foot of the Toowoomba range.
Atrocious weather forced authorities to suspend efforts to reach dozens of people stranded on rooftops and at other locations in the valley last night.
The focus of concern is the valley communities of Grantham, where about 40 people were trapped overnight, and Withcott, where people spent the night on rooftops.
Nine Network reporter Cameron Price is at Grantham and told the ABC the town had been devastated.
"The town is like a cyclone has gone through it," he said.
"There are houses that are completely collapsed, cars that are halfway up trees, homes a kilometre away from where they were.
"The terrible news from here is that they took the bodies of two small children from the waters, they are the fifth and sixth victims here so far."
State Premier Anna Bligh said this morning eight people had died in the Toowoomba area and another 11 were missing (since revised upward by rescue authorities to 72 people).
She said wet weather was hampering the rescue efforts and the search for the missing people.
