In March 1946 the Department of Works and Housing requested that a geological examination be made of the Upper Cotter Valley in the vicinity of Kangaroo Creek to determine whether a dam could be constructed near the junction of Kangaroo Creek with the Cotter River. A geological examination was subsequently made. This report deals primarily with a possible dam site, near the mouth of Kangaroo Creek, and includes only a brief addition to the general geology of the Upper Cotter Valley. The location, physiography, general geology, engineering geology, and recommendations for future work are discussed in this report.

At the request of the Tasmanian Hydro-Electric Commission a geophysical survey was carried out along a tunnel line at Trevallyn, a suburb of Launceston, North Eastern Tasmania. The excavation of the Trevallyn tunnel is part of the Hydro-Electric Trevallyn Power Development project to utilise the water of the South Esk river for generation of electric power. The construction works are already well advanced. A dam is being built on the river at the Second Basin. Water from the catchment will be diverted through a tunnel two miles long to a power station situated at sea level on the Tamar River. A locality map is given in Plate 1. Three geophysical exploration methods, electrical, seismic and gravitational, were used to locate deeply weathered and fractured zones in the dolerite bedrock, through which the tunnel is being driven.

Details and results are given of a seismic refraction survey made at the request of the Hydro-Electric Commission of Tasmania, to investigate the site of the western portal of the proposed Mossy Marsh Tunnel. The tunnel is part of the No. 2 Tarraleah Canal project to transport water from Lake King William to Tarraleah Power Station. The primary object of the survey was to determine the thickness of till overlying the dolerite bedrock, and hence contours of the bedrock surface.

On 29th September, 1948, the writer, assisted by K.R. Fleischman, spent one day examining the rocks of the Cotter River Valley in the neighbourhood of the dam and mapping geological features which would have a bearing on the proposed extensions. Representative rocks were collected from the quarries on the right bank of the River below the dam. The mapping was done by chain, compass and Abney level. Aspects of general geology and engineering geology are discussed in this report. Two accompanying geological plans are included.

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 has been prepared at the request of Engineers of the Department of Works and Housing. The writer spent a day with Mr. Crotty examining the site, and another day alone studying general geological conditions relevant to the proposed scheme. The visit and its findings are outlined in this report.

This report covers the work done by the author who was geophysicist with the Australian National Antarctic Research Expedition at Macquarie Island from April to December, 1953. It is a sequel to Records 1953/30 and 1954/32 and deals with observatory routine and maintenance and other general duties required of the geophysicist. The report contains the results of absolute magnetic observations and initial earthquake phases. Detailed tables of scientific results will be published separately in reports at present in preparation.

This web service delivers data from an aggregation of sources, including several Geoscience Australia databases (provinces (PROVS), mineral resources (OZMIN), energy systems (AERA, ENERGY_SYSTEMS) and water (HYDROGEOLOGY). Information is grouped based on a modified version of the Australian Bureau of Statistics (ABS) 2021 Indigenous Regions (IREG). Data covers population centres, top industries, a regional summary, groundwater resources and uses, energy production and potential across six sources and two energy storage options. Mineral production and potential covers 36 commodities that are grouped into 13 groups.
