The critical success factors which control hydrocarbon prospectivity in the Otway Basin have been investigated using petroleum systems approaches. Greater than 99% of the hydrocarbon inventory within the Victorian Otway Basin has been sourced from Austral 2 (Albian-Aptian) source rocks and these accumulations are typically located either within, or within approximately 3,000 m of source rock kitchens which are at peak thermal maturity at present day. Importantly, the zones of greatest prospectivity are located where these source rocks have been actively generating and expelling hydrocarbons throughout the Late Tertiary, primarily as a result of sediment loading associated with progradation of the Heytesbury shelfal carbonates. This peak generation window occurs at an average depth of approximately 2,500-3,500 m 'sub-mud' across much of the basin, which has allowed prospective hydrocarbon fairways to be mapped out, thereby highlighting areas of greatest prospectivity. It is believed that the spatial proximity of the actively generating source rocks to the accumulations is due to several factors, which includes overall poor fault seal in the basin (success cases occur where charge rate exceeds leakage rate) and relatively complex and tortuous migration fairways (which means that large volumes of hydrocarbons are only focussed and migrate for relatively short distances). etc

From 1995 to 2000 information from the federal and state governments was compiled for Comprehensive Regional Assessments (CRA), which formed the basis for Regional Forest Agreements (RFA) that identified areas for conservation to meet targets agreed by the Commonwealth Government with the United Nations. These 3 CDs were created as part of GA's contribution to the Tasmania CRA. CD1 contains final versions of all data coverages and shapefiles used in the project, and final versions of documents provided for publishing. CD2 contains Published Graphics files in ArcInfo (.gra), postscript (.ps) and Web ready (.gif) formats. CD3 contains all Geophysical Images and Landsat data.

Presentation made to the Second Symposium on Resource Assessment Methodologies organised by the Potential Gas Committee and the US Geological Survey. Discussed methodology used at Geoscience Australia and presented some recent results from the Bonaparte and Browse basins.

Earth comprises systems of enormous complexity that sustain all life and control the distribution of our mineral, energy and water resources. Increasingly earth scientists are now moving away from focusing on single domain research on understanding isolated parts of these intricate systems to adopting multidisciplinary, computationally intensive integrated methodologies to model and simulate the real world complexities of earth systems science. Simultaneously developments in information technology are increasing the capacity of computational systems to credibly simulate complex systems. Real world Solid Earth and Environmental Science data sets are extremely heterogenous, complex and large, and are currently in the order of terabytes (1012 bytes). However, the size and complexity of geoscience data sets are also exponentially increasing, as more powerful modern computing systems combine with enhanced engineering capacity to design and build automated instruments to collect more data and new data types. We are rapidly moving into an era when Earth Scientists will need to have the capacity to analyse petabyte (1015 bytes) databases if they are to realistically model and simulate complex earth processes. Although digital geoscientific data sets are becoming increasingly available over the Internet, current Internet technologies only allow for the downloading of data (if the connection is fast enough): integration, processing and analysis then has to take place locally. As data sets get larger and more complex, then large computational resources are required to effectively process these data. Such resources are increasingly only available to the major industry players, which in turn creates a strong bias against the Small to Middle Enterprises, as well as many University researchers. For those that do not have access to large-scale computing resources, analysis of these voluminous data sets has to be compromised by dividing the data set into smaller units, accepting sub-optimal solutions and/or introducing sub-optimal approximations. It is clear that if we are to begin grappling with accurate analysis of large-scale geoscientific data sets to enable sustainable management of our mineral, energy and water resources, then current computational infrastructures are no longer viable.

At its 4th meeting in Brisbane on 21st and 22nd August, the Copper and Bauxite Committee arranged a conference with Mr. J. Kruttschnitt, Managing Director of the Mt. Isa Mines, at which officers of the Department of Mines of Queensland were present, to discuss ways and means of quickly exploiting the recently indicated copper ore body situated in the Hanging Wall of the Black Star Lode at Mt. Isa Mine. At the request of the Committee, and following discussion of the details between all parties, Mr. Kruttschnitt made a proposal, which is submitted herewith.

The Committee has given consideration to the desire of the Government to put into production any property that can materially add to Australia's copper output within two years. As pointed out in another submission of even date, it seems probable that 5,000 tons of new copper p.a. can be obtained from a recently discovered ore body in the Mt. Isa Mines, production commencing in January, 1942, if the necessary capital loan is made as recommended. In addition, it seems likely that a worth while production could be obtained from other mines in the Cloncurry district. The principle potential sources of increased supply are Hampden Consols, Mt. Oxide and Trekelano, but many other smaller properties can also be looked to, provided some central treatment facilities are available.

This record contains the results of a geological framework study of the southern half of the Lord Howe Rise and adjacent areas, including the Tasman Basin and the New Caledonia Basin. The report particularly focuses on the geological evolution and the resource potential.

On Saturday, 20th September, we visited the Chemistry Department, Crawley, Western Australia, and saw the experimental plant erected for the treatment of Lake Campion alunite. The process was discussed with Professor Bayliss and Mr. H. Bowley, Government Mineralogist and Assayer. On the morning of Monday, 22nd September, we met the Minister for Mines, State Officials and Messrs. F.B. Norwood and L. Gibbons at the Mines Department, Perth. At this meeting the Whim Creek and Ravensthorpe (Phillips River) copper areas were discussed. On the afternoon of the 22nd we met the Aluminium Panel at the Department of Industry and discussed the Lake Campion proposals. On Tuesday 23rd, lateritic bauxites were examined as several localities on the Darling Range and at Toodyay. Following is a review of the matters discussed in Western Australia.
