Rainfall has been decreasing in eastern and south-western Australia since the 1950s while increasing in north-western Australia. Importantly, rainfall intensity and frequency have changed; rainfall events are predicted to become more extreme, driven by a warmer, wetter atmosphere. This means there are likely to be more and larger flood events like that seen in Queensland, NSW and Victoria in the summer of 2010/11.
