Victorian Coastal Cliff Assessment: Instability Areas for 2040 with 0.2m Sea Level Rise

A digital spatial dataset from the Victorian Department of Energy, Environment and Climate Action models future coastal cliff erosion scenarios for the state of Victoria. The dataset includes layers for toe erosion and cliff instability, projecting conditions for the year 2040 under a 0.2-meter sea level rise scenario. It supersedes the Stage 1 assessment and was last updated in June 2026.

Use Cases

• Modeling future cliff toe retreat based on historical erosion rates and projected sea level rise.
• Assessing areas prone to episodic cliff instability events, from rock falls to large-scale mass movement.
• Informing regional-scale coastal management and hazard planning for Victoria's coastline.

Strengths

• Projection for a specific future year (2040) and sea level rise scenario (0.2m).
• Explicitly supersedes a previous assessment (Stage 1), indicating versioned updates.
• 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 not suitable for individual property scale assessments, limiting granular use.
