The project addresses the urgent need for a national-level dataset by sourcing data from various state governments and identifying gaps in coverage. The dataset integrates contributions from OpenStreetMap (OSM), Smartline, and state-based government databases, resulting in a research-quality geospatial file. Key attributes include the location and type of coastal structures, with data standardised for consistency across regions. Limitations are noted, such as the absence of government-supplied data for certain regions and potential accuracy issues with OSM-sourced information. The dataset is intended for research purposes, supporting efforts to assess coastal risks and guide future protection measures. Ongoing updates to datasets will extend to not only consider engineered hard structures but also include datasets of nature-based coastal protection (e.g., restored reefs and coastal vegetation).
