Map depicting the proposed new Two Way Route throught the Great Barrier Reef for consultative purposes. Distributed solely for comment , not in force. NOT FOR NAVIGATION. Vector and point data of proposed Two Way Route and Vessel position copyright 2013 Australian Marine Safety Authority. Access to Hydro Charts has been provided on the basis that they should be used for review of waterspace management changes in the GBR only. Additionally, as the charts have been de-projected, and subject to the normal practices of notice to Mariners, which will gradually render these particular editions outdated over time, they should not be used for navigation.

Geoscience Australia defines a borehole as the generalized term for any narrow shaft drilled in the ground, either vertically or horizontally, and would include Mineral Drillholes, Petroleum Wells and Water Bores along with a variety of others types, but does not include Costean, Trench or Pit. For the purposes of a Water Well as defined by Groundwater ML v1.0, the dataset has been restricted to onshore Australian boreholes only, and bores that have the potential to support assessment of groundwater resources, within a Bioregional Assessment.

OZCHEM is Geoscience Australia's national whole-rock geochemical database. This release of OZCHEM contains over 50000 analyses of rocks, regolith and stream sediments from many regions of Australia. Each analysis includes a geographic location and a geological description, which includes the host stratigraphic unit, where known, and the lithology. Most samples have been collected by Geoscience Australia's field parties. OZCHEM is stored in an ORACLE relational database and is available in comma-delimited flat ASCII format. The data set is also bundled with documentation explaining the database structure and includes definitions of the database tables and columns (attributes).

Geoscience Australia may refer to a specimen as a sample of (material), that is, a limited quantity of something which is intended to be similar to or represent a larger amount of that material. Observations and measurements are recorded that relate to a specimen.

This map was produced as part of a 2006 series depicting Australian commonwealth fisheries and shows the area of Orange Roughy Zones with the Southern and Eastern Scalefish and Shark Fishery. The series of pdf's are available for public download from AFMA's website and the shapefiles for public download from GA's website.

Australian Petroleum Blocks (2014) - Aligned with the current Australian Maritime Boundary Dataset (AMB2014) The digital realisation of Australia's Graticular Framework as set out under the Offshore Petroleum and Greenhouse Gas Storage Act 2006. Web Service Capabilities WMS,WFS,WCS. The dataset was created internally by Geoscience Australia using the framework described in Section 33 of the Offshore Petroleum and Greenhouse Gas Storage Act 2006 (OPGGS Act) and previous Acts. The international, scheduled areas and coastal waters used in this dataset are those found in the current Australian Maritime Boundary Dataset (AMB2014). The dataset is comprised of both polygons and points created to very high precision, accurate to within millimetres. The blocks have been cut by Australia's international boundaries, the scheduled areas and the coastal waters. Each block is assigned a polygon, including partial blocks. All blocks are titled with their block ID, and a list of vertices that make up the blocks. Each vertex of the dataset is also replicated as a discrete point in the points dataset. The design of the dataset allows for the exact location of every vertex to be know to millimetre precision. The corner coordinates of blocks are now defined to a high precision, and can be found by querying the appropriate point. Existing production licences AC/P17, AC/RL4, and AC/RL5 are included in the dataset. The blocks are attributed with fields containing information on: Block ID Parent 1 Million Mapsheet Offshore Area Epoch of the boundaries used to cut the data - AMB2014 Datum Origin of the mapsheet in AGD66 The position of all vertices in the block The number of vertices in the block The area of the block in acres The area of the block in hectares The calculation used to find the area of the blocks is estimated to be precise to better than 1%. This is considered to be sufficient as under the permit and licensing arrangements in the OPGGS Act, the area of a block has no relevance. Therefore the area figure is provided solely for reference.
