A ground-motion database is developed for earthquakes occurring in Australian continental crust. The Australian Ground-Motion Database (AGMD) collects and processes earthquake recordings using consistent, repeatable methods, and brings together detailed information about the earthquakes, recording stations, and waveforms. The AGMD now includes over 5,000 ground-motion records from 270 earthquakes that occurred between 1990 and 2025, recorded by over 1000 stations across 36 different permanent and temporary networks. Each recording is processed using the U.S. Geological Survey (USGS) “gmprocess” software and saved in structured HDF5 workspace files. A cloud-based web portal gives open access to the data, allowing users to search, view, and download both waveforms and calculated ground-motion parameters. The system uses Amazon Web Services (AWS) to manage large-scale data uploads and a PostgreSQL database for fast and reliable data access.  These data will have utility for improving seismic hazard assessments in Australia and analog tectonic regions and will provide engineering practitioners with access to a repository of earthquake time histories that can be used to support engineering design.
