Victorian Coastal Cliff Assessment: Instability Areas for Present Day

Modelled spatial data identifies areas of cliff toe erosion and episodic instability along the Victorian coastline. The dataset is recommended for statewide or regional scale assessments and supersedes earlier Stage 1 outputs. It was published by the Department of Energy, Environment and Climate Action and last updated in June 2026.

Use Cases

• Modeling gradual cliff toe retreat based on historical erosion rates and future sea level rise factors.
• Identifying areas prone to episodic cliff instability events, from small rock falls to large-scale mass movements.
• Planning coastal management strategies based on statewide spatial layers of erosion scenarios.
• Assessing the impact of marine processes, weathering, and bio-erosion on soft and hard cliff stability.

Strengths

• Dataset is an update that supersedes previous Stage 1 assessment outputs.
• Available under a permissive CC-BY-4.0 license.
• Includes multiple spatial file formats (TAB, SHP, GDB, etc.) for compatibility.

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.
