Port Fairy Coastal Hazard Lines for Erosion and Sea Level Rise

The Port Fairy Local Coastal Hazard Assessment (LCHA) provides geospatial data on coastal hazard extents and physical impacts for the Port Fairy area. It models shoreline setback due to erosion under the assumption that existing seawalls remain in place, incorporating allowances for storm erosion, dune stability, underlying recession, and future sea level rise across planning horizons for 2050, 2080, and 2100. The dataset is published by the Department of Energy, Environment and Climate Action on data.gov.au and was last updated in April 2026.

Use Cases

• Modeling future coastal erosion risk based on the defined setback components (S1, S2, S3, S4).
• Informing land-use planning and development setbacks using hazard lines for present day, 2050, 2080, and 2100.
• Assessing infrastructure vulnerability by referencing specific elevation contours like +6 m AHD and +2 m AHD mentioned in the methodology.
• Validating coastal hazard models against the specific sea level rise projections of 0.4 m (2050), 0.8 m (2080), and 1.2 m (2100).

Strengths

• Explicitly defines the four key setback components (S1-S4) and their combination for four distinct planning horizons.
• Provides specific sea level rise projections used: 0.4 m for 2050, 0.8 m for 2080, and 1.2 m for 2100.
• References specific elevation contours (+6 m AHD, +2 m AHD) used as baselines for hazard line derivation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and spatial resolution are unknown, which may limit suitability assessment.
• Users must consult external project reports on the Our Coast website to fully understand data limitations.
