Homes ruined in New South Wales flooding

Serious flooding in New South Wales has left half a million people under evacuation orders or warnings. One of the worst hit is the northern city of Lismore where floodwaters were so high that hundreds of residents perched on their rooftops waiting to be rescued. The disaster started last weekend when 700 millimetres of rain fell in just a day. Binnie O'Dwyer lives in Lismore and her home has been ruined by the floodwaters.
