Flooding and flood risk management have a long history in Australia. In 1817, frustrated by recurrent flood disasters and expenditures on disaster relief, the Governor of New South Wales, Lachlan Macquarie, wrote to settlers with a General Order recommending relocation of farms and no compensation otherwise. This threat was precipitated by settlers building and occupying locations that endangered people, property, and public finances. From 2022 onwards, Australia has again experienced a series of disastrous flood events that have stretched the capacity, resilience, and psyche of the population, leading to expressions of frustration from all involved. These floods have highlighted persistent failures of flood risk management that appear to be worsening. In the two centuries since Lachlan's frustration with our inability to reduce flood risk, it appears that little has changed.
