Abstract
This paper is an introduction to the two AJEM Special Issues on risk assessment. The role of risk assessment in emergency management in Australia is firmly established. Considerable progress has been made in utilising risk modelling tools and supporting data to develop new information on risk for some hazards. Several key achievements relating to the governance and science of natural disaster risk assessment are highlighted here and, while significant further work is required to reach an understanding of all hazards risks nationally, the way forward is clear.
