The Australian Bathymetry and Topography web service includes the topography of Australia and the bathymetry of the adjoining Australian Exclusive Economic Zone. The area selected does not include data from Australia's marine jurisdiction offshore from the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. The 2009 bathymetry data were compiled by Geoscience Australia from multibeam and single beam data, and along with the topography (onshore) data, was derived from multiple sources. As per the 2005 grid, the 0.0025 dd resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist) (Webster and Petkovic, 2005). In areas where no sounding data are available (in waters off the Australian shelf), the grid is based on the 2 arc minute ETOPO (Smith and Sandwell, 1997) and 1 arc minute ETOPO (Amante and Eakins, 2008) satellite derived bathymetry. The topographic data (onshore data) is based on the revised Australian 0.0025dd topography grid (Geoscience Australia, 2008), the 0.0025dd New Zealand topography grid (Geographx, 2008) and the 90m SRTM DEM (Jarvis et al, 2008).

The Geomorphic Features of Australia's Marine Jurisdiction web service brings together various datasets produced by Geoscience Australia that describe the distribution and types of geomorphic features found on the seabed of Australia's marine jurisdiction. This jurisdiction covers Australia's Exclusive Economic Zone, including offshore islands and territories. Geomorphic features have been identified using the best available bathymetric data with features generally mapped at a scale of 1:5 000 000.

The Marine Survey Geomorphology Web Map Service contains the local scale (1:10 000) interpreted geomorphology maps available for download on Geoscience Australia's website. These interpreted geomorphology maps have been produced for numerous marine survey programs conducted in Australian mainland and Antarctic waters by both Geoscience Australia and our collaborators. Layers are grouped by survey or region and where available include both the Geoscience Australia and vessel survey identification numbers that contributed to each dataset.

The map and underlying digital dataset provide national and regional-scale context for a wider variety of applications, including offshore industries, area-based environmental management, scientific research and public education. Australia’s Seabed Map is based on the revised AusBathyTopo 250m (Australia) 2023 grid (Beaman, 2023), the most comprehensive, continental-scale compilation of bathymetry data in the Australian region. The map extends across a vast area from 92°E to 172° E and 8°S to 60° S. This includes areas adjacent to the Australian continent and Tasmania, and surrounding Macquarie Island and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. Australia's marine jurisdiction offshore from the territory of Heard and McDonald Islands and the Australian Antarctic Territory are not included. The new map provides a complete three-dimensional picture of the seafloor and is a significant improvement since it was last revised in 2009. In particular, the map incorporates new innovations such as the use of earth observation data (satellite based) produced by Digital Earth Australia to improve coastline definition and present a seamless transition between land and sea. The data is compiled from 1582 individual surveys using multibeam echosounders, single-beam echosounders, LiDAR, or 3D seismic first returns, as well as higher-resolution regional compilations, and other source data including Electronic Navigation Charts and satellite derived bathymetry. The new map represents decades of data collection, analysis, investment and collaboration from Australia’s seabed mapping community. The 250 m resolution is only supported where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist). In many regions, this 250 m grid size is far in excess of the optimal grid size for some of the input data used. The AusBathyTopo250m grid and higher-resolution regional datasets are available on the AusSeabed Marine Data Portal as the AusBathyTopo Series. This map is not suitable for use as an aid to navigation, or to replace any products produced by the Australian Hydrographic Office. Medium: Digital PDF download.
