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. Consolidated shorelines, which include soil and rock cliffs, are not able to rebuild following periods of erosion but rather are subject to a one-way process of degradation. ASCCIEs typically have two components: • Toe Erosion A gradual retreat of the cliff toe caused by weathering, marine and bio-erosion processes. This retreat will be affected by global process such as sea level rise and potentially increased soil moisture. Future cliff toe position based on historical erosion rates with a factor applied to allow for the effect of future sea level rise. • Cliff Instability Episodic instability events are predominately due to a change in loading or material properties of the cliff or yielding along a geological structure. In soft cliffs, instability causes the cliff slope to flatten to a slope under which it is “stable” (geo-mechanically). Soil cliff slope instabilities are influenced by processes that erode and destabilise the cliff toe, including marine processes, weathering and biological erosion or change the stress within the cliff slope. Most of the hard cliffs are stable at very steep angles. Instability events may range from small-scale instabilities (block or rock falls) or discontinuities, to cliff slope instability cause by large-scale and deep-seated mass movement. The latter mode of failure in hard cliffs is rare. 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.

This dataset depicts the location of the Danyo, Hindmarsh, Tyrell, Avoca and Leaghur faults in the north-western Murray Basin in Victoria. The faults have been digitised from Macumber (1991) and Robson and Webb (2011). These north-south oriented faults appear to truncate or interrupt a number of cross-cutting structures in the Murray Basin. The Hindmarsh, Tyrell, Avoca and Leaghur faults all influence modern day stream flows which may be indicative of an earlier impact on the aquifer if movement has occurred regularly over the Tertiary period. The dataset was compiled by GHD to inform the report 'Potential Influences of Geological Structures on Groundwater Flow Systems' for DEPI's Secure Allocation Future Entitlements (SAFE) Project.

This layer is part of Vicmap Lite and contains point features delineating airport areas. Vicmap Lite datasets are suited for use between scales of 1: 250,000 and 1 : 5 million. The point features were sourced from Vicmap Transport. The level of attribute information and the number of features has been simplified to suit the 1: 250,000 - 1 : 5 million scale range. The concept of a Scale Use Code has been introduced to help control the level of detail displayed. This dataset includes the Civil Aviation Safety Authority (CASA) 3 tier classification. THIS DATASET WAS LAST UPDATED IN SEPTEMBER 2021

The CAR Reserve dataset is derived from the PLM25 and FMZ100 datasets that were extracted in December 2019 and represents the approximate location and extent of areas reserved in dedicated and informal reserves, current as at 31 March 2020. The dedicated reserve reflects the spatial extent of Parks and Reserves from PLM25. The informal reserve reflects spatial extent of Special Protection Zone (SPZ) from the FMZ100 layer. Values protected by prescription, which form part of the informal reserve component of the CAR reserve are not presented in the dataset as values protected by prescription are subject to field verification.

Point data describing the location and key characteristics of all PGPs that are currently under active management by VicForests. The data consists of one point for each PGP that is classified as 'current' in VicForests' network of PGPs. PGPs that have been retired or abandoned are not included in the dataset. PGPs are permanently demarcated areas of forest that are periodically measured over long periods of time (20-50 years) and they require protection from unplanned disturbance events such fuel reduction burns.

This layer contains species distribution maps for taxa groups across the Victorian coastline.
