Port Phillip Bay Coastal Erosion Extent for 2100 with 1.1m Sea Level Rise

Port Phillip Bay coastal hazard assessment data includes modelled erosion, inundation, and groundwater hazard extents for various sea level rise scenarios. The dataset is provided by the Department of Energy, Environment and Climate Action and was last updated in June 2026. It is recommended for regional-scale planning around Port Phillip Bay and is supported by technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).

Use Cases

• Model regional coastal erosion risk based on projected sea level rise scenarios.
• Assess storm tide inundation extents for the 1% Annual Exceedance Probability event.
• Identify areas with shallow groundwater hazards (within 0-2m of land surface) under different sea level rise conditions.
• Compare hazard extents across different percentiles (95th, 50th, 5th) for inundation scenarios.

Strengths

• Includes multiple hazard types (erosion, inundation, groundwater) across a range of sea level rise scenarios (0m to 1.4m).
• Data is supported by cited technical reports from CSIRO (2022), Water Technology (2023), and Kennedy (2022).
• Available in multiple geospatial file formats (TAB, SHP, GDB, etc.) for compatibility.
• Released under a permissive CC-BY-4.0 license.

Limitations

• Description metadata is limited; actual data quality and column definitions require manual inspection after download.
• The product is explicitly stated as not suitable for individual property-scale assessments.
• Row count and dataset size are unknown, which may limit suitability assessment for large-scale ML tasks.
