Again, thousands of residents in Western Sydney face a life-threatening flood disaster. At the time of writing, evacuation orders spanned southwest and northwest Sydney and residents of the Hawkesbury-Nepean Valley were being warned the crisis was escalating.

It’s just over a year since the region’s long-suffering residents lived through one of the largest flood events in recent history. And of course, earlier this year floods devastated the Northern NSW town of Lismore.
