The north western Tasmania Bathymetry 1:25000 depicts bathymetric contours from Robbins Island [144deg 53min, -40deg 44min] to West Head [146deg 43min, -41deg 44min] from the coastline to 1500m from the coastline. The contour intervals are at 2 metre intervals. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and to support Natural Resource management priorities in the Northern NRM region of Tasmania. It is not to be used for navigational purposes.

The Bicheno to Schouten Island marine habitat project 1:25000 depicts marine habitats from Diamond Island [148deg 17min, -41deg 51min] to Schouten Island [148deg 19min, -42deg 22min] from the coastline to 1500m from the coastline. The habitat types depicted in the dataset include Reef, Sand, and Seagrass. The data was collected through intensive field sampling from February to September 2006 by marine researchers at the Tasmanian Aquaculture and Fisheries Institute. The use of underwater camera equipment, echo sounder data and a Differential GPS unit allowed for the extensive area to be surveyed. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995.

Bathymetric contours (5 m interval) for Tasmanian coastal waters from the LWM (Low water mark) to 40 metres in depth or 1.5 kms from shore (whichever boundary is first identified). Detailed bathymetric contours were developed to be used to fulfill coastal management objectives according to The Living Marine Resources Act 1995.

Geoscience Australia carried out marine surveys in southeast Tasmania in 2008 and 2009 (GA0315) to map seabed bathymetry and characterise benthic environments through observation of habitats using underwater towed video. Data was acquired using the Tasmania Aquaculture and Fisheries Institute (TAFI) Research Vessel Challenger. Bathymetric mapping was undertaken in seven survey areas, including: Freycinet Pensinula (83 sq km, east coast and shelf); Tasman Peninsula (117 sq km, east coast and shelf); Port Arthur and adjacent open coast (17 sq km); The Friars (41 sq km, south of Bruny Island); lower Huon River estuary (39 sq km); D Entrecastreaux Channel (7 sq km, at Tinderbox north of Bruny Island), and; Maria Island (3 sq km, western side). Video characterisations of the seabed concentrated on areas of bedrock reef and adjacent seabed in all mapped areas, except for D Entrecastreaux Channel and Maria Island. friars_1 is an ArcINFO grid of the Friars islets, south of Bruny Island survey area produced from the processed EM3002 bathymetry data using the CARIS HIPS and SIPS software. This dataset is a contribution to the CERF Marine Biodiversity Hub.

The Macquarie Harbour - 1:25,000 Series depicts bathymetric contours from Hells Gate [145d 13m, -42d 13m] to the mouth of the Gordon River [145d 31m, -42d 26m]. The contours are at 5 metre intervals. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995. It is not to be used for navigational purposes.

Geoscience Australia and the National Oceans Office carried out a joint venture project to produce a consistent, high-quality 9 arc second (0.0025 degree or ~250 m at the equator) bathymetric data grid of those parts of the Australian water column jurisdiction lying between 92E and 172E and 8S and 60S. As well as the waters adjacent to the continent of Australia and Tasmania, the area selected also covers the area of water column jurisdiction surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands. The area selected does not include Australias marine jurisdiction off of the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. The underlying data from which this grid is derived can only support this resolution in areas where direct bathymetric observations are sufficiently dense (e.g. where swath bathymetry data or digitised chart data exist). In areas where only track-line data exist, the grid resolution is high along-line but low perpendicular to lines. In areas where no sounding data are available, the grid is based on interpolated or indirectly observed bathymetry, and these data can only support a resolution of 2 arc minutes (2 nautical miles or ~3.7 km). The grid covers an area of approximately 41 million square kilometres. Its dimensions are 32003 x 20803 cells resulting in a file size slightly in excess of 1.3 Gb of 2-bytes integer numbers representing the bathymetric values. The grid synthesises approximately 1.7 billion observed data points. This grid is not suitable for use as an aid to navigation, or to replace any products produced by the Australian Hydrographic Service. This dataset is a contribution to the CERF Marine Biodiversity Hub and is hosted temporarily by CMAR on behalf of Geoscience Australia.

The Tasmanian Estuaries (Georges Bay) Bathymetry 1:25000 depicts bathymetric contours for Georges Bay, St Helens from the mean high water mark to the deepest part of the main basin at 25 m. The contour intervals are at 1 metre intervals. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and to support Natural Resource management priorities in the Northern NRM region of Tasmania. It is not to be used for navigational purposes.

The Kent Group marine contour map 1:25000 depicts bathymetric contours from the coastlines of the islands of the Kent Group to the 3nm offshore limit. The contour intervals are at 5 metres. The dataset is intended to be used to fulfil coastal management objectives according to The Living Marine Resources Act 1995 and is not to be used for navigational purposes.
