  • The Australian Resource Reviews are periodic national assessments of individual mineral commodities. The reviews include evaluations of short-term and long-term trends for each mineral resource, world rankings, production data, significant exploration results and an overview of mining industry developments.

  • A large proportion of Australia’s onshore sedimentary basins remain exploration frontiers. Industry interest in these basins has recently increased due to the global and domestic energy demand, and the growth in unconventional hydrocarbon exploration. In 2016, Geoscience Australia released an assessment of eight central Australian basins that summarised the current status of geoscientific knowledge and petroleum exploration, and the key questions, for each basin. This publication provides a comprehensive assessment of the geology, petroleum systems, exploration status and data coverage for additional three basins in western and central Australia: the Canning, Perth and Officer basins. The Perth and Canning basins are producing petroleum basins, however, they may be regarded as frontier basins for unconventional hydrocarbon resources. The Officer Basin is a large, unproven frontier basin which has seen little exploration to date.

  • The earthquake impact scenario outlined in this Professional Opinion was initially developed to support the Australian Vulnerability Profile (AVP) Project. The project is led by Emergency Management Australia and aims to better articulate what makes Australia vulnerable to disaster when severe-to-catastrophic natural hazards impact what Australians value. The Profile will narrate at the national level Australia’s vulnerabilities and contribute to a better understanding of where to target mitigation, develop policy and direct efforts to improve resilience. As part of the project, a number of workshops have been held with stakeholders to foster discussion amongst key government and non-government stakeholder groups and academic disciplines to inform how we strategically prepare for long-term resilience and how we can reduce and manage systematic risks. A scenario modelling a magnitude 6.5 earthquake near the Adelaide business district was developed by Geoscience Australia (GA) for use at the AVP stakeholder workshop, held in Adelaide on 23-24 November 2016. The South Australian Fire and Emergency Services Commission (SAFECOM) has subsequently made a request to use this scenario for further detailed state-based planning initiatives. This report is being prepared to support these initiatives and provide the necessary background for future reference. This report provides the: • background to why this earthquake scenario was selected; • the geological and geophysical context in which it is placed; • the historical seismicity for the area; and • a qualitative description of the estimated impact to the Adelaide region. Key assumptions and limitations in the approach are summarised below: • A rare earthquake event was selected given the premise of the AVP project (i.e. severe-to-catastrophic event). • The event was modelled using GA’s Earthquake Risk Model (EQRM). • An Exposure Report is provided based on GA’s National Exposure Information System (NEXIS). • A qualitative assessment of impact is outlined based on the estimated level of earthquake ground shaking. In summary, this potential impact could be commensurate with that experienced in Christchurch from the magnitude 6.3 22 February 2011 earthquake.

    Gravity data measures small changes in gravity due to changes in the density of rocks beneath the Earth's surface. The data collected are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. This Australia wide AFGN Absolute 2013 (P201391) contains a total of 11 point data values acquired at a spacing of 750 metres. The data is located in ACT, NSW, NT, QLD, SA, TAS, VIC, WA and were acquired in 2013, under project No. 201391 for Geoscience Australia.

  • <p>This dataset contains magnetotelluric data and a 3D inversion model from the 09GA-GA1 deep magnetotelluric transect, collected in Central Australia in 2009. The transect is 350 km long, with data acquired from 18 stations with both broadband and long period instrumentation, and 21 stations with broadband instrumentation only (a total of 39 sites). The resulting station spacing is 10km for the broadband stations, and 20km for stations with both broadband and long period instrumentation. We have reprocessed the broadband data using the Bounded Influence, Remote Reference Processing software (BIRRP), yielding an extended bandwidth of 0.003 to 1300 s and merged these data with the long period data. We have inverted the data using the ModEM 3D inversion code. <p>More details on the data processing, analysis, modelling, and interpretation can be found in the following paper: Kirkby, A. and Duan, J., 2019.
