Floods: 10 of the deadliest in Australian history

While Australia is described as the driest inhabited continent on Earth, right now it might seem hard to believe.

Floods can devastate local communities, but they also impact the entire economy - examples include the flood levy imposed in taxes following the south-east Queensland floods in 2010/2011, and also inflated banana prices after the same floods destroyed 75 per cent of the crop.
