Victorian Coastal Cliff Assessment - Cliff Face Landslip Areas (ASTaR) - Present day - 0.0m SLR

The Victorian Coastal Cliff Assessment - Instability Areas (ASCCIE) is a digital dataset consisting of multiple spatial layer outputs from modelled erosion scenarios. The dataset is recommended for use at the statewide / regional scale along the Victorian coastline. Application of the data should be guided by the accompanying Victorian Coastal Cliff Assessment technical reports and expert advice. The product is not suitable for individual property scale assessments.

ASTaR have been derived based on the geological unit type and cliff height. The methodology for defining ASTaR is a new method undertaken at a high level and based on the existing cliff height and a defined slope to identify the possible seaward extent of talus runout. For this state-wide/regional scale assessment, single values were derived for each component. This ‘building-block’ approach (ie: a combination of individual parameters) is expected to produce ‘upper bound’, conservative results, which identifies areas potentially exposed to coastal erosion, cliff instability and cliff slumping/talus

The product is an update to the Victorian Coastal Cliff Assessment, Stage 1. Included datasets for Stage 2a supersede the Stage 1 outputs. The Stage 2a project report should be read in conjunction with the Stage 1 report. Application of the data should be guided by the accompanying "Victorian Coastal Cliff Assessment, Stage 2a technical report" (Tonkin & Taylor 2025) read in conjunction with the Stage 1 technical report, combined with appropriate expert advice.
