Australia’s coastline is exposed to climate change and sea-level rise impacts from erosion, inundation, and changes to storm tracks and intensity. It accommodates about 80% of the population. Around 250 local councils are responsible for coastal management, with very different capacities to undertake adaptation. A decision support framework was developed to support coastal managers seeking to understand present-day and future climate change, its impacts and possible response options. Extensive engagement was undertaken with practitioners before commencing the design and at all stages of the build, in order to ensure usefulness and usability. The resulting framework, CoastAdapt (coastadapt.com.au), provides comprehensive guidance and support, including understanding of climate change science, expected impacts, and adaptation options. It contains datasets on historical flooding; present-day coastal sensitivity to erosion; and future climate extremes, sea-level rise, and inundation for each coastal council. A risk management framework supports users through the six stages of adaptation from identifying the challenges through to monitoring and evaluation. The performance of CoastAdapt has been evaluated through 11 6-week test cases with coastal managers in the public and private sectors. In future, if CoastAdapt is to remain a useful resource, it must be seen by practitioners as dynamic, relevant, and current, and on-going resources will be needed to achieve this.
