Mulitbeam echosounder (MBES) bathymetry data were collected offshore of Shellharbour, NSW in 2017. Bathymetry data coverage extends from Port Kembla to Bass Point, and ranges from 10 to 64 m water depth. This dataset represents a classification of seabed landforms derived from this MBES, which delineates the prominent seabed features observed. This classification defines areas of reefs, peaks, plains, scarps, depressions and channels. Features were classified using the Seabed Landforms Classification Toolset developed for ArcGIS by the Coastal and Marine Unit, DPE (Linklater et al. 2023) which are publicly available on SEED (https://datasets.seed.nsw.gov.au/dataset/seabed-landforms-classification-toolset) and GitHub (https://github.com/LinklaterM/Seabed-Landforms-Classification-Toolset/). A preliminary classification of this Shellharbour survey was presented in Kinsela et al. (2020), and this classification represents the final interpreted product for this survey. This dataset contributes toward an understanding of the distribution of submerged reefs along the NSW coast, which provides fundamental baseline information for managers, users and custodians of the marine environment. The source MBES dataset for this classification is available on the Australian Ocean Data Network portal: https://portal.aodn.org.au/ Linklater, M., Morris, B.D. and Hanslow, D.J.
