The study provides a comprehensive analysis of the natural gases from the Bonaparte, Browse, Carnarvon and Perth basins (in 4 modules). Geochemical analyses for the molecular and carbon isotope composition were performed on 96 gases and associated liquids, and these data are interpreted in a geological context. Additional non-exclusive data from the AGSO database have been used for correlation/interpretation purposes. The study addresses factors influencing the composition of gaseous and other light hydrocarbons in natural gas (and associated oil accumulations) including; - primary source and maturity controls, - secondary alteration processes, e.g. migration fractionation, water washing, biodegradation, and - multiple charge histories, including deep dry gas inputs.

Hydrogeological assessment of the Maryborough Basin, submitted as an abstract for the 2013 IAH Congress.

Coastal aquifers are vulnerable to seawater intrusion, which is a significant issue in Australia. Geoscience Australia and the Nation Centre of Groundwater Research and Training undertook an assessment of Australia's vulnerability to seawater intrusion. The assessment utilised multiple approaches, including a vulnerability factor analysis; typological analysis; mathematical analysis; qualitative and quantitative analysis; and future land surface inundation and population growth analysis. This is presented as an abstract for the 2013 IAH Congress.

The possibility of diverting the Upper Snowy River to provide water for irrigation has been a subject of discussion since 1884. The Snowy Mountains Hydro-Electric Authority was constituted in 1949. As the body responsible for the detailed investigation of the geology of the area it was thought desirable to publish the geological work which has been done in the Snowy Mountains region. With the authority of the Under-Secretary of the Department of Mines, New South Wales, the reports by members of the Geological Survey of New South Wales are included together with reports by geologists of the Commonwealth Bureau of Mineral Resources, Geology and Geophysics. Reports included in this publications are: "Geology - Jindabyne to Murrumbidgee River", "Reconnaissance Survey of Dam Site at Geehi, Swampy Plain River, N.S.W", "Geological Reconnaissance of the Proposed Hydro-Electric Works in the Kosciusko Area", "Geological Reconnaissance - Eucumbene River to Tumut River", and "Geological Reconnaissance - Murrumbidgee - Tumut Area".

This report is a summary of information collected between November, 1948 and July, 1949 in the course of visits to the United Kingdom and the United States. The main subjects investigated were the complete gasification of coal, particularly in respect of its application to Victorian brown coal, the production of oil by synthesis and the production and refining of shale oil. Information was sought on a considerable number of other interests in the field of fuel technology as the opportunity offered. The authorities consulted were invariably experts in their respective fields, and great care was taken to record their information accurately. The report is a summary of recent developments and not an exhaustive study of the subjects mentioned. A considerable mass of detail has been excluded but is available on record for further reference.

For the projected development of the hydroelectric power resources of the Laloki River, Papua, a diversion weir will be required. Two sites have been selected by the officers of the Department of Works and Housing, downstream from Rouna Falls and another site, upstream from the falls, which would be suitable for a large scale power development. An inspection of these sites was made in order to indicate any geological difficulties which may be expected. The situation, physiography, and geology of the proposed sites, as well as the suitability of these sites, are discussed in this report.

The Pine Creek AEM survey was flown over the Pine Creek Orogen in the Northern Territory during 2008 and 2009 as part of the Australian Government's Onshore Energy Security Program at Geoscience Australia (GA). The survey covers an area of 74,000 km2 from Darwin to Katherine in the Northern Territory which hosts several world class deposits, including the Ranger Uranium Mine, Nabarlek, Mt Todd, Moline and Cosmo Howley. Aimed at regional mapping, uranium exploration, reducing exploration risk and promoting exploration activity, the program worked closely with industry partners to infill wide regional line spacing (5km) with deposit scale line spacing (less than 1km). The survey results are relevant in exploration for a variety of commodities and resources, including uranium, copper, lead, zinc, gold, nickel and groundwater. Geoscience Australia's interpretation products include sample-by-sample layered earth inversion products comprising located data, geo-located conductivity depth sections, depth slice grids, elevation slice grids, inversion report and an interpretation report. All data and products are available from GA as well as the Northern Territory Geological Survey Geophysical Image Web Server.
