Victorian Coastal Cliff Assessment: Instability Areas for 2070 with 0.5m Sea Level Rise

Victoria's coastline is covered by a digital dataset of modelled erosion scenarios for cliffs. The dataset consists of multiple spatial layers projecting instability areas for 2070 under a 0.5-meter sea level rise scenario. It was produced by the Department of Energy, Environment and Climate Action and updated in June 2026.

Use Cases

• Modeling future cliff toe erosion based on historical rates and sea level rise factors mentioned in the description
• Identifying areas prone to episodic cliff instability events described as ranging from rock falls to deep-seated mass movement
• Assessing coastal degradation risks for consolidated shorelines that cannot rebuild after erosion
• Planning regional-scale coastal adaptation strategies based on modelled erosion scenarios

Strengths

• Dataset is an update to Stage 1, superseding previous outputs
• Includes multiple spatial layers in formats like SHP, GDB, and DXF
• Projected for a specific future scenario (2070 with 0.5m sea level rise)

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 not suitable for individual property scale assessments, as stated in the description
