Australian Marine Spatial Layers for Decision Support

Over 80 integrated geospatial layers cover the Australian Marine Jurisdiction, including maritime boundaries, bathymetry, environmental data, legal interests, fisheries, and shipping. The Australian Ocean Data Network developed this system, which was last updated in April 2026. Information is sourced from Geoscience Australia, other government agencies, and industry.

Use Cases

• Analyze shipping lane density against bathymetry and environmental layers for maritime traffic planning.
• Model potential fisheries zones by correlating bathymetric data with known fishery activity layers.
• Assess legal and regulatory constraints for offshore development using maritime boundaries and legal interests layers.
• Integrate physical and environmental information layers for coastal erosion or habitat change studies.

Strengths

• Contains over 80 distinct geospatial information layers.
• Data is integrated from multiple authoritative sources including Geoscience Australia.

Limitations

• Specific row counts, file sizes, and column details for the underlying data are unknown.
• The primary access is an interactive web system (HTML), not a direct download of raw datasets.
• The description cautions against using the information as the sole source for commercial or operational decisions.
