This dataset contains the 2009 Special Offshore Petroleum Acreage Release Areas. The regular release off offshore acreage is a key part of the Australian Government's strategy to encourage investmant in petroleum exploration. The 2009 special release consists of 2 areas.

This GIS dataset represents digital files accompanying the Index of Airborne Geophysical Surveys (13th edition) 2013, which presents a summary of specifications of open file surveys held in GA's National Airborne Geophysical Database. The product provides spatial coverage and metadata for all magnetic, radiometric and AEM surveys for which spatial information is available, current to 21 March 2013. The GIS dataset is useful for making maps showing the coverage of open file Australian airborne geophysical surveys.

Since 2012, Geoscience Australia has been providing spatial support and advice to the Crisis Coordination Centre (CCC) within Emergency Management Australia (EMA) as part of our collaboration with the Attorney-General's Department. The GA Exposure Report was developed to provide timely exposure information for emergency response and decision-making. The Exposure Report is generated by extracting relevant demographic, building, business, agriculture, institution and infrastructure attributes from the National Exposure information System (NEXIS) in an event footprint, geographical boundary or area of interest.

The `Inferred Isotopic Domain Boundaries of Australia data set is based on an interpretation of the recently released Neodymium depleted mantle model age map of Australia (GA Record 2013/44). The isotopic map of Australia was produced by gridding two-stage depleted mantle model ages calculated from Sm-Nd isotopic data for just over 1490 samples of felsic igneous rocks throughout Australia. The resultant isotopic map serves as a proxy for bulk crustal ages and accordingly allows the potential recognition of geological domains with differing geological histories. One of the major aims of the Neodymium depleted mantle model age map, therefore, was to use the isotopic map (and associated data) to aid in the recognition and definition of crustal blocks (geological terranes) at the continental and regional scale. Such boundaries are recognisable by regional changes in isotopic signature but are hindered by the variable and often low density of isotopic data points. Accordingly two major procedures have been adopted to locate the regional distribution of such boundaries across the geological continent. In areas of high data density (and high confidence), such as the Yilgarn Craton Western Australia, isotopic data alone was used to delineate crustal domains. In such regions it is evident that identified crustal blocks often but not universally approximate known geological terranes. In areas of moderate data density (and corresponding moderate confidence) (smoothed) boundaries of known geological provinces were used as a proxy for the isotopic boundary. For both high and moderate data densities identified crustal boundaries were extended (with corresponding less confidence) into regions of lower data density. In areas of low data density (and low confidence) boundaries were either based on other geological and/or geophysical data sets or were not attempted. The latter was particularly the case for regions covered by thick sedimentary successions. Two levels of confidence have been documented, namely the level of confidence in the location of the isotopic domain boundary, and the level of confidence that a boundary may actually exist. The `Inferred Isotopic Domain Boundaries of Australia map shows the locations of inferred boundaries of isotopic domains, which are assumed to represent the crustal blocks that comprise the Australia continent. The map therefore provides constraints on the three dimensional architecture of Australia, and allows a better understanding of how the Australian continent was constructed from the Mesoarchean through to the Phanerozoic. It is best viewed as a dynamic dataset, which will need to be refined and updated as new information, such as new isotopic data, becomes available.

Geoscience Australia's wall map of Australia is ideal for displays and feature walls in offices, classrooms and conference rooms. The four component sheets - North-East, North-West, South-East and South-West are available individually, with each map 103cm x 88cm. The fully assembled size is 2m x 1.7m. At this scale 1cm on the map represents 25km on the ground. Product Specifications Coverage: Complete coverage of Australia Currency: Last revised 2011 Coordinates: Geographical Datum: AGD66 (GDA94 compliant at this scale); AHD Projection: Simple Conic on two standard parallels (18S and 36S)

This dataset represents the distribution of Petroleum titles for the Australasian region. This attributed dataset is used in production of the "Petroleum Exploration and Development Titles" map published annually in APRIL. Attributes and an additional lookup table contain information on the operator, dates of award and expiry, the State who has jurisdiction, and the companies and their equity for each title.
