Port Phillip Bay Coastal Hazard Assessment for 0.2m Sea Level Rise

Multiple spatial layers from the Port Phillip Bay Coastal Hazard Assessment model storm tide inundation, erosion, and groundwater hazards. The dataset includes extents for a 1% Annual Exceedance Probability event combined with sea level rise scenarios ranging from 0m to 1.4m. The Department of Energy, Environment and Climate Action published this data, which was last updated in April 2026.

Use Cases

• Model regional-scale storm tide inundation risk based on combined percentile layers.
• Assess coastal erosion extents based on 95th percentile hazard modelling.
• Map areas of shallow groundwater hazard based on depth raster derivations.
• Compare coastal hazard impacts across different sea level rise scenarios.

Strengths

• Includes multiple hazard types: inundation, erosion, and groundwater.
• Covers a range of sea level rise scenarios from 0m to 1.4m.
• Data is supported by referenced technical reports from CSIRO and other organizations.
• Available in multiple geospatial file formats including SHP, GDB, and DXF.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The product is explicitly not suitable for individual property scale assessments.
