Geoscience Australia houses one of the world's largest collections of petroleum data. Much of this data is non-confidential and available to the petroleum industry, research organisations and the public. The collection includes well data submitted by industry under legislative requirements as well as data collected by research projects and marine surveys undertaken by Geoscience Australia or other government agencies or institutions. The collections comprise of digital data such as well completion reports, well logs, destructive analysis reports, vertical seismic profiles, core photography, special studies and also hard-copy well log data and graphs submitted during the pre-digital era. <b>Value: </b> information related to the subsurface that have the potential to support geological investigations and assessment of a variety of resources. <b>This data can be discovered through the National Offshore Petroleum Information Management System (NOPIMS) - https://www.ga.gov.au/nopims</b>

Collection of field notebooks recording mainly geological observations made by staff of Geoscience Australia (GA) and its predecessors, Bureau of Mineral Resources (BMR) and Australian Geological Survey Organisation (AGSO), while conducting fieldwork between 1930 and 2010. The notebooks are currently being digitised. <b>Value: </b>Historic and scientific significance. Many sites visited are remote and have rarely been revisited. Some notebooks also record observations on fauna and flora. <b>Scope: </b>Geographical scope is largely Australia, pre- and post-Independence Papua New Guinea (PNG), and the Australian Antarctic Territory, but other countries and territories are represented.

Papua New Guinea (PNG) lies in a belt of intense tectonic activity that experiences high levels of seismicity. Although this seismicity poses significant risks to society, the Building Code of PNG and its underpinning seismic loading requirements have not been revised since 1982. This study aims to partially address this gap by updating the seismic zoning map on which the earthquake loading component of the building code is based. We performed a new probabilistic seismic hazard assessment for PNG using the OpenQuake software developed by the Global Earthquake Model Foundation (Pagani et al. 2014). Among other enhancements, for the first time together with background sources, individual fault sources are implemented to represent active major and microplate boundaries in the region to better constrain the earthquake-rate and seismic-source models. The seismic-source model also models intraslab, Wadati–Benioff zone seismicity in a more realistic way using a continuous slab volume to constrain the finite ruptures of such events. The results suggest a high level of hazard in the coastal areas of the Huon Peninsula and the New Britain – Bougainville region, and a relatively low level of hazard in the southwestern part of mainland PNG. In comparison with the seismic zonation map in the current design standard, it can be noted that the spatial distribution of seismic hazard used for building design does not match the bedrock hazard distribution of this study. In particular, the high seismic hazard of the Huon Peninsula in the revised assessment is not captured in the current building code of PNG. <b>Citation:</b> Ghasemi, H., Cummins, P., Weatherill, G. <i>et al.</i> Seismotectonic model and probabilistic seismic hazard assessment for Papua New Guinea. <i>Bull Earthquake Eng, </i><b>18</b>, 6571–6605 (2020). https://doi.org/10.1007/s10518-020-00966-1
