Developed in the 1990s and operational since 2001, Tweed Sand Bypassing (TSB) is one of Australia’s most innovative coastal engineering solutions. It is a marine sand transportation project jointly administered by the Queensland and New South Wales Governments. The aims are to restore the natural coastal sand drift to the Southern Gold Coast beaches and to ensure a navigable Tweed River entrance.

TSB has an extensive collection of environmental, social, and economic data which is used to determine and understand the various impacts of the project. A cloud-based Geographic Information System (GIS) database is being developed to provide a new way to store, visualise, analyse, and interpret this data to better understand relationships, patterns and trends for enhanced decision making and project management.

The GIS cloud platform will create an interactive operational picture , providing a consolidated and integrated single view of what-where-when things are happening – empowering inter-state project staff and the community, supporting broader dissemination of information to all TSB stakeholders, while ensuring the best sustainable outcome is achieved for our coastal environment.
