Deluges that have gone before: floods in Australian history

As flash floods, tidal surges, cyclones, burst riverbanks and downpours have impacted on much of Eastern Australia, we've heard many references to the floods that have gone before. These floods stand as markers and reference points, in both practical and symbolic ways. But what do we really know of these past floods? And what happens as we move beyond lived memory? Using the Brisbane floods of 1974 and 1893 as reference points, Rear Vision traces some of the stories of flood, and asks what is remembered, whose stories remain, and whether the murky state of collective memory obscures other stories, and other floods.
