Due to licence restrictions on the National Electricity Transmission Lines dataset, the metadata statement is the only information available for release. For further information contact clientservices@ga.gov.au This dataset contains the high voltage electricity transmission lines that make up the electricity transmission network in Australia .

This dataset provides the spatially continuous data of the seabed sand content (sediment fraction 63-2000 mm) expressed as a weight percentage ranging from 0 to 100%, presented in 0.01 decimal degree resolution raster format. The dataset covers the Australian continental EEZ, including seabed surrounding Tasmania. It does not include areas surrounding Macquarie Island, and the Australian Territories of Norfolk Island, Christmas Island, and Cocos (Keeling) Islands or Australia's marine jurisdiction off of the Territory of Heard and McDonald Islands and the Australian Antarctic Territory. This dataset supersedes previous predictions of sediment sand content for the Australian Margin with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant regions. This dataset is intended for use at national and regional scales. The dataset may not be appropriate for use at local scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and interpolations updated.

Australia has a thriving oil and gas industry with expanding infrastructure and many exploration opportunities. Geologically the country contains potential for large oil and gas discoveries with extensive sedimentary basins. Australia is also one of the world leaders in providing low cost geological data with an open Acreage Release process and competitive taxation regimes. Politically Australia is very stable with a very high standard of living and a long-standing democratic culture based on the rights of the individual and the rule of the law. There is a free market philosophy which welcomes foreign investment - Australia has no mandatory local equity requirements and has no government owned oil companies. Government facilitation of investment includes fast-tracking of approvals processes for major projects. This CD provides some basic Australia data including: Oil and Gas Resources of Australia 2003 This publication is the definitive reference on exploration, development and production of Australia's petroleum resources. It covers exploration, reserves, undiscovered resources, development, coalbed methane resources, production, crude oil and shale oil and supporting information and statistics. It includes a forecast of Australia's crude oil and condensate production up to the year 2020, and sustainability indicators for petroleum resources. Information on Australia's petroleum data availability is also included. An estimate of Australia's undiscovered oil and gas potential and a review of geological sequestration of carbon dioxide in Australia is included. Australian Research and Promotional Material Australian research includes research papers for Australia, Australia regions (Northwest Shelf and the Southern Margin) and CO2 Sequestration. Promotional materials refer to pamphlets which outline geological products available from Geoscience Australia and contacts for obtaining these products. This material is grouped by region with the research papers. Geoscience Australia Online Databases Demonstration The Geoscience Australia Petroleum Databases Demonstration is a Microsoft Powerpoint presentation containing instructions on how to use Geoscience Australia's online Petroleum Databases located at: www.ga.gov.au/oracle/apcrc/ This output represents the data which is considered open file and commercial-in-confidence.

Current understanding of Australia's geothermal resources is based on limited data such as temperature measurements taken in petroleum and mineral boreholes across the country. Heat flow studies are rarer, with existing publicly available compilations containing less than 150 heat flow data-points for Australia. Both temperature and heat flow data are unevenly distributed and, where no data exist, the available information has been interpolated over large areas to generate national-scale maps. Geoscience Australia has acquired the field and laboratory equipment required to measure heat flow. It began thermal logging of boreholes across Australia in late 2008 and has since collected 155 temperature logs. In late 2009, the thermal conductivity meter became operational, allowing the project to begin thermal conductivity measurements of samples collected from logged boreholes. To help clear some of the backlog of samples collected during 2008-09, the measurement of some of these samples has been contracted out. This record details the first set of new heat flow interpretations to be released by Geoscience Australia. The remaining temperature logs will be interpreted for heat flow and released, as thermal conductivity data for these holes become available.

The data set provides outlines for the maximum extent of Australian geological provinces and their components, including sedimentary, igneous and metallogenic provinces, both onshore and offshore. These data were compiled as part of Geoscience Australia's integrated digital information system to provide improved accessibility and knowledge relating to the petroleum and minerals geology and prospectivity, and to provide a national stratigraphic and tectonic framework for Australia. The current dataset is not complete for Australia, and covers only offshore sedimentary provinces and a selection of sedimentary, igneous and metallogenic provinces in onshore Australia.

This keynote address was presented at the Australian Nickel Conference held in Perth, 13-14 October 2004. Nickel-sulphide deposits in Australia are mainly associated with Archaean komatiites and Archaean Proterozoic mafic intrusions, but some unusual Phanerozoic deposits occur in eastern Australia. The majority of Australia's nickel production (~80%) is derived from komatiite deposits in the Yilgarn Craton of Western Australia. The Eastern Goldfields Province of this craton hosts one of the greatest concentrations of Archaean komatiite-hosted nickel deposits in the world, several of which are world class (>1 Mt Ni). Exploration activities in Australia are currently focussed on mafic-ultramafic rocks in Late Archaean and Proterozoic provinces. Exploration has been stimulated by the discovery of new deposits (Flying Fox, Daybreak, Armstrong, Daltons, McEwen, Nebo-Babel), recognition of different styles of mineralisation (Avebury), and the protracted period of elevated nickel metal prices. There is considerable potential for finding new deposits associated with komatiites and mafic intrusions, particularly under shallow cover. Geoscience Australia has undertaken new research initiatives that define favourable mineralising elements, exploration strategies, and new nickel metallogenic provinces.

This data set contains information on Oil and Gas pipeline infrastructure. This dataset has been converted from Microstation format used in a map "Petroleum Exploration and Development Titles" published annually in APRIL. Attributes have been added to comply with data standards and minor coding of line work has been achieved using annotation from the map. Further data has been added, specifically for the specific Acreage Release Areas.
