    Combined Port Phillip Bay habitat model developed by DELWP 2021 and Open Coast Deakin marine mapping campaign JAN 2019. The PPB map was built to predict habitat distributions by applying Random Forest machine learning tools which integrate ground truthed data and environmental predictors. The resulting Habitat Complex map represents 19 different habitat complexes across Port Phillip Bay at Level 3 Combined Biotope Classification Scheme (CBiCS) described by Edmunds and Flynn (2015, 2018; 2021). A total of 8,325 ground-truth records were used within the model (of the 9,683 records) that met the Random Forest modelling criteria (¿5 unique values for each biotope category; Breiman 2001). Environmental parameters were sourced from different methods including lidar, multibeam, and indexes calculated from the Digital Elevation Model (DEM), and mapped at a resolution of 2.5 metres. The Random forest model produced an accuracy (Out-of-bag) of 91%.

(2011). Deakin Marine Mapping (Young M et al, 2018). GeoHab Victoria Estuaries Geomorphology (2010). Deakin Marine Mapping (Zavalas, R et al. 2018), DELWP wetlands (1994), Monk et al 2011, Roob and Ball (1997), Ford et al 2016, Edmunds and Flynn (2015), Blake and Ball (2001), Poore (1992), Cohen et al (2000). The map has later been reclassified to CBICS habitat classification scheme at broad-scale level 2 and 3.

    This data contains information about the distribution of seagrass around the Australian coastline. It was prepared by Dr. Hugh Kirkman (CSIRO Division of Fisheries) from a review of published and unpublished sources, and updated by Dr. Ian Hahmdorf, (Bureau of Rural Sciences). General info: CAMRIS, standing for the Coastal and Marine Resources Information System, is a small-scale spatial analysis system developed in collaboration by several divisions of Australia's Commonwealth Scientific and Industrial Research Organisation (CSIRO), as part of the CSIRO Coastal Zone Program. CSIRO Division of Wildlife and Ecology was the custodian of the 'coastal' subset of the Australian Resources Information System (ARIS). Coastal ARIS became the core dataset of the CAMRIS project. The Coastal ARIS database was developed from a coastal inventory developed by Galloway et al. This inventory contained relatively large scale data including landform, geology, vegetation, soil, land use, climate and population information for each of 3027 3x10km sections around the coastline of mainland Australia and Tasmania, but excluding offshore islands.

    This record describes a single aggregated dataset of the geomorphic habitat environment (facies) for Australia's 7 states and territories: New South Wales, Victoria, Tasmania, Queensland, Northern Territory, South Australia, Western Australia. The classification system contains 12 easily identifiable and representative environments: Barrier/back-barrier, Bedrock, Central Basin, Channel, Coral, Flood- and Ebb-tide Delta, Fluvial (bay-head) Delta, Intertidal Flats, Mangrove, Rocky Reef, Saltmarsh/Saltflat, Tidal Sand Banks (and Unassigned). These types represent habitats found across all coastal systems in Australia. For the New South Wales region, 134 coastal waterways are described. Most of the estuaries of New South Wales are under intense land use pressure with approximately 80% of the State's population living near an estuary (NSW Dept of Land and Water Conservation) For the Victorian region, 54 coastal waterways are described. Most of the 54 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition. For the Tasmanian region, 88 coastal waterways are described. The majority of near pristine estuaries in Tasmania are located in the south and west of the State and on Cape Barren Island, according to the Department of Primary Industries, Water and Environment. For the Queensland region, 213 coastal waterways are described. Southern and central Great Barrier Reef lagoon coasts have a broad spectrum of river, tide and wave- dominated estuaries. For the Northern Territory region, 63 coastal waterways are described. Estuaries on the northern Arnhem Land, Gulf of Carpentaria coasts are predominantly tide-dominated estuaries, which vary greatly in size and floodplain characteristics. For the South Australia region, 36 coastal waterways are described. Most of the 36 coastal waterways have a "Modified" environmental condition (as opposed to "Near Pristine"), according to the National Land and Water Resources Audit definition. For the Western Australia region, 103 coastal waterways are described. Western Australia has a diverse range of Estuaries due to different climates. Ranging from mostly "near pristine" and tide influenced estuaries in the north to "near pristine" wave dominated estuaries in the southwest region.

    The Victorian seabed habitat map documents the distribution of broad benthic habitat types in Victorian Coastal Waters to the State’s 3 nautical mile jurisdictional limit. The map was created using a top-down modelling process whereby habitat descriptors were assigned using seafloor structure and biological information derived from multibeam sonar (Victorian Marine Habitat Mapping Project), bathymetric LiDAR (Future Coasts program) and observations from underwater video. Identification of benthic biota, to the lowest discernible taxonomic level, and substrate characteristics were recorded according to the Victorian Towed Video Classification scheme (Ierodiaconou et al. 2007).
