The present work has been undertaken as part of a long-term project of describing the Permian pelecypod and gastropod faunas of Western Australia and western Northern Territory and of assessing their stratigraphical significance. Two portions have already appeared (Dickins, 1956; 1957). In the first paper pelecypods from earlier collections obtained from various parts of the sequence in the Carnarvon Basin were described; and in the second the earliest Permian (Sakmarian) pelecypod and gastropod fauna from the Lyons Group and the Carrandibby Formation. Other current work in palaeontology is being undertaken by B. E. Balme (pollen and microplankton), B. F. Glenister (ammonoids), G. M. Philip (crinoids and blastoids), June R. P. Ross (bryozoans), and G. A. Thomas (brachiopods). For faunal studies, the Permian rocks of the western part of Australia have the merit that the Lower Permian* has a complex of changing marine faunas which allow a detailed study of their phylogeny and range. The value of this sequence is enhanced by the presence of marine Upper Permian in the Fitzroy and Bonaparte Gulf Basins. It represents as complete a marine Permian sequence as any in Australia, if not the most complete, and is rivalled only by that of the Hunter Valley of New South Wales. The collections used have been mainly from the Geology Department of the University of Western Australia and from the Museum of the Geological Branch of the Bureau of Mineral Resources, Geology and Geophysics, Canberra. The Bureau of Mineral Resources collections include material from West Australian Petroleum Pty Limited.

The Overflow No. 1 Well was drilled on the South Moreton Anticline in Authority to Prospect 7lP, south-east Queensland, to a total depth of 2993 feet. The well drilled in Bundamba Sandstone to 310 feet, Ipswich Coal Measures from 310 feet to 1605 feet, and volcanic rocks of probable early Triassic or Upper Palaeozoic age from 1605 feet to total depth. Drilling operations commenced on 8th April, 1960, and the well was abandoned as a dry hole on 18th May, 1960. The drilling contractor was Mines Administration Pty Limited, Brisbane, and the rig used was a National Ideal 55. The operation provided for a programme of electric and mud logging, testing and coring. The well was abandoned short of the target depth of 6500 feet because of the hard drilling and poor petroleum prospects in the thick volcanic sequence. Minor oil and gas showings in the well were closely associated with coal seams.

Conorada Ooroonoo No. 1, located in the north-western part of Authority to Prospect 75P, Queensland, was drilled as an off-structure stratigraphic test by Conorada Petroleum Corporation. The contractor was Mines Administration Pty Ltd, and the rig used was a Sullivan 300A owned by the contractor. The well was spudded in on 20th July, 1960, and abandoned as a dry hole at total depth of 3852 feet on 23rd August, 1960. A complete section of Great Artesian Basin sediments was drilled and granitic basement penetrated at 3840 feet. The coring and sampling programme carried out enabled as much information to be obtained about the section as was possible.
