How can residents know their flood risk? A review of online flood information availability in Australia

Abstract

Widespread flooding across eastern Australia between November 2010 and February 2011 has again highlighted the country's susceptibility to natural disasters. The floods have also triggered discussion about flood awareness, risk information, and the role and responsibility of governments, insurance providers and residents. This paper examines the availability of flood hazard information on local government websites in Australia; it was completed in mid-2010 before the 2010–2011 flooding. The quality and accessibility of information is discussed, as are variations based on state and population size of different Local Government Areas (councils). Particular attention is given to those areas that experienced recent flooding, as well as to known areas of concentrated risk. There are large gaps in information availability, with less than 50% of councils provided flood risk information. A higher percentage of councils in the more populous states, some of which also have higher flood risk, provide information than those in less-populous states. Of those councils with a recognised flood risk, 67% provided flood information online.
