Australia tells tens of thousands to flee floods

Deadly floods swept Australia's east coast on Tuesday, stranding people on bridges and rooftops and forcing tens of thousands to flee their homes.

Dozens of emergency warnings are in effect across the states of Queensland and New South Wales, where a week-long "rain bomb" has dumped 3.2 feet of water on some areas.

Several waterways have burst their banks or broken through levees, inundating towns and forcing residents to evacuate or seek safety on higher ground.

Nine people have died and more than a thousand people have been rescued. Authorities have warned that more fatalities are likely.

The latest victim was a woman in her 80s whose body was found by police inside a home in the country town of Lismore. 

"She is yet to be formally identified," said New South Wales Police. 

In the usually laid back surf town of Byron Bay, Hannah Leser had enjoyed the weekend celebrating her wedding with 150 guests.

But the new bride and groom are now rescuing friends stranded in the nearby towns of Ballina and Mullumbimby in a borrowed four-wheel-drive.

About 30 people are camped at a house where the couple were to spend their honeymoon.

"It's chaos but all of our friends and family are safe," she told AFP. "This is not quite the honeymoon I expected but it is what it is."

Australia's military has deployed two MRH-90 Taipan helicopters to aid the rescue effort.

In one daring aerial rescue, the crew plucked two people to safety as muddy waters lapped at the corrugated metal roofing of their home.

Live television images on public broadcaster ABC showed a rescuer sitting on the roof with the pair, preparing to strap them to the chopper's winch.
