The Forbes Geology GIS comprises a digital compilation of regional geological mapping of the Forbes 1:250,000 sheet by AGSO and the NSW DMR under the National Geoscience Mapping Accord from 1995 to 1999. The data package includes all mapping data from the 6 component 1:100,000 geological sheets; Parkes, Grenfell, Bogan Gate, Marsden, Condobolin and Wyalong. The GIS includes polygon and line layers depicting outcropping and buried rock types, structures, and regolith landforms. It also includes point layers depicting outcrop descriptions; mineral occurrences; geochemical, thin section and geochronological samples; georeferenced photographs; structural readings; and drill hole locations. Images of AGSO's airborne magnetic and radiometric data, and a depth to slightly weathered bedrock model are included.

This Record describes techniques which can be used to predict surface deformation caused by natural or anthropogenic subsurface fluid changes. Using predictive (forward) models, simulations have been developed to estimate the range of surface deformation caused by the Coal Seam Gas (CSG) extraction operations in the Surat Basin. The objectives of this research were to: - Develop a predictive model that enables Geoscience Australia to estimate the magnitude and areal extent of surface deformation caused by natural or anthropogenic fluid activities. - Report the capability, accuracy and limitations of the predictive model. - Apply the predictive model to Coal Seam Gas operations in the Surat Basin, Queensland. - Describe the monitoring techniques capable of measuring subsurface fluid changes - Discuss how geodetic data can be used to constrain the poroelastic properties of reservoirs.

Editors; Hoatson, D.M. and Lewis, B.C. Authors: Hoatson, D.M., Miezitis, Y., Jaireth, S. and Huston, D.L. The major aims of this report are to review the distribution, geological characteristics, resources, and potential of PGEs in Australia, and provide a mineral-systems-based framework for successful low-risk exploration. A mineral-system approach has been used to classify ~500 PGE deposits and occurrences documented in this report. This approach focuses on mineral-forming processes critical to the formation of a particular deposit. It differs from descriptive classifications in that it can be used to predict new areas and types of PGE mineralisation. The classification used is hierarchical in structure, with the highest-level category of deposits called 'Mineral-System Class'. There are twelve major classes that fall within the broad-mineral systems: Orthomagmatic (classes 1 to 7), Hydrothermal-Metamorphic (class 8), Regolith-Laterite (class 9), Placer (class 10), Astrobleme-related (class 11), and a final class with minor or unknown economic importance (class 12). This report concludes that, as seen globally, mineralised stratabound layers in Precambrian layered mafic-ultramafic intrusions in Australia are considered to have high potential for a major economic PGE resource. Such layers are attractive targets as they display: lateral continuity; have uniform grades (1 g/t to 6 g/t Pt+Pd+Au) and thicknesses; contain a significant component of the elements Pt, Pd, Rh, Au; and have potential for large-tonnage multi-element deposits (PGEs, Cr, Cu, Ni, Co, Au). Large Igneous Provinces may also provide opportunities for major economic PGE resource discoveries, despite the challenges of: defining favourable mineralised environments across large areas and under cover; lack of reliable geochronological and geochemical data for identifying different phases of the magmatic system; and a general perception that the global type example (Norilsk-Talnakh in Russia) may be a 'unique' mineral system.

Landslides are a complex geological hazard triggered by a combination of factors depending on their magnitude and type (Figure 1). There are a number of methodologies employed for landslide susceptibility mapping around the world. The method adopted should vary according to the individual characteristics of the landslide being considered. The method of landslide susceptibility mapping adopted here was developed using an existing method, the InfoVal method (van Westen 1997), adapting it for use with the open source software QGIS. QGIS was chosen as the GIS system due to its use by other natural hazard scientists in Papua New Guinea and in the region, and because it is free and open source.

Results from the 2012 SPAC (Spatial Autocorrelation) survey that collected data at 25 sites in Newcastle and 2 in Sydney are presented. Two approaches to the analysis of the SPAC data were compared as well as comparison with the results of direct measurement.

The Sea Level Monitoring Project was initially developed in the early 1990's (known at that time as the South Pacific Sea Level and Climate Monitoring Project) as a response to concerns expressed by South Pacific Forum Leaders about the potential impacts of global warming on sea levels and climate in the South Pacific. This Australian aid project was established with the goal of providing an accurate, long term record of sea levels in the South Pacific both for Forum countries and for the international scientific community that need such information to better understand how the Pacific oceanographic and meteorological environment is changing. During the 1990's a network of high resolution sea level and climate monitoring stations was established in the South West Pacific and observations from those stations were made available to stakeholders. In 2001, a Continuous Global Positioning System (CGPS) monitoring component was added and CGPS instruments were established near and linked to the sea level tide gauges stations in all partner countries so as to enable the measurement of vertical land movements. Vertical land motion at sea level stations can be equal or larger than the local absolute sea level signal, thus masking sea level change related information recorded at those stations. Therefore, the CGPS network is a crucial component for reliably determining absolute sea level change. This document reports the analysis results of CGPS coordinate time series from 2001 to 2013.

An Australian-wide certification campaign of positions in accordance with Regulation 13 of the National Measurement Regulations 1999 and the National Measurement Act 1960 has been run from 00:00:00 (UTC time) Sunday 07 September 2014 to 00:00:00 (UTC time) Sunday 14 September 2014 (GPS week 1809). The primary objective of this campaign was to improve the consistency of legally traceable CORS positions across Australia, and confirm that CORS stations with a valid Regulation 13 Certificate conform to their stated uncertainties. As of 30 November 2014, twelve applications for verification of a reference standard of measurement under Regulation 12 of the National Measurement Regulations 1999 have been received for verification of GDA94 position on their owned or managed station monuments. This report documents the processing and analysis of the national Regulation 13 campaign GPS data for the stations to satisfy the position verification requirements.
