The northern Pedirka Basin in the Northern Territory is sparsely explored compared with its southern counterpart in South Australia. Only seven wells and 2,500 km of seismic data occur over a prospective area of 73,000 km2 which comprises three stacked sedimentary basins of Palaeozoic to Mesozoic age. In this area three petroleum systems have potential related to important source intervals in the Early Jurassic Eromanga Basin (Poolowanna Formation), the Triassic Simpson Basin (Peera Peera Formation) and Early Permian Pedirka Basin (Purni Formation). They are variably developed in three prospective depocentres, the Eringa Trough, the Madigan Trough and the northern Poolowanna Trough. Basin modelling using modern techniques indicate oil and gas expulsion responded to increasing early Late Cretaceous temperatures in part due to sediment loading (Winton Formation). Using a composite kinetic model, oil and gas expulsion from coal rich source rocks were largely coincident at this time, when source rocks entered the wet gas maturation window.The Purni Formation coals provide the richest source rocks and equate to the lower Patchawarra Formation in the Cooper Basin. Widespread well intersections indicate that glacial outwash sandstones at the base of the Purni Formation, herein referred to as the Tirrawarra Sandstone equivalent, have regional extent and are an important exploration target as well as providing a direct correlation with the prolific Patchawarra/Tirrawarra petroleum system found in the Cooper Basin.An integrated investigation into the hydrocarbon charge and migration history of Colson–1 was carried out using CSIRO Petroleum’s OMI (Oil Migration Intervals), QGF (Quantitative Grain Fluorescence) and GOI (Grains with Oil Inclusions) technologies. In the Early Jurassic Poolowanna Formation between 1984 and 2054 mRT, elevated QGF intensities, evidence of oil inclusions and abundant fluorescing material trapped in quartz grains and low displacement pressure measurements collectively indicate the presence of palaeo-oil and gas accumulation over this 70 m interval. This is consistent with the current oil show indications such as staining, cut fluorescence, mud gas and surface solvent extraction within this reservoir interval. Multiple hydrocarbon migration pathways are also indicated in sandstones of the lower Algebuckina Sandstone, basal Poolowanna Formation and Tirrawarra Sandstone equivalent. This is a significant upgrade in hydrocarbon prospectivity, given previous perceptions of relatively poor quality and largely immature source rocks in the Basin.Conventional structural targets are numerous, but the timing of hydrocarbon expulsion dictates that those with an older drape and compaction component will be more prospective than those dominated by Tertiary reactivation which may have resulted in remigration or leakage. Preference should also apply to those structures adjacent to generative source kitchens on relatively short migration pathways. Early formed stratigraphic traps at the level of the Tirrawarra Sandstone equivalent and Poolowanna Formation are also attractive targets. Cyclic sedimentation in the Poolowanna Formation results in two upward fining cycles which compartmentalise the sequence into two reservoir–seal configurations. Basal fluvial sandstone reservoirs grade upwards into topset shale/coal lithologies which form effective semi-regional seals. Onlap of the basal cycle onto the Late Triassic unconformity offers opportunities for stratigraphic entrapment.

The Australian Government formally releases new offshore exploration areas at the annual APPEA conference. This year, 31 areas plus two special areas in five offshore basins are being released for work program bidding. Closing dates for bid submissions are either six or twelve months after the release date (i.e. 3 December 2009 and 29 April 2010), depending on the exploration status in these areas is and on data availability. The 2009 release areas are located in Commonwealth waters offshore Northern Territory, Western Australia, South Australia and Victoria, comprising intensively explored areas close to existing production as well as new frontiers. As usual, the North West Shelf features very prominently and is complimented by new areas along the southern margin, including frontier exploration areas in the Ceduna Sub-basin (Bight Basin) and the Otway Basin. The Bonaparte Basin is represented by one release area in the Malita Graben, while five areas are available in the Southern Browse Basin in an under-explored area of the basin. A total of 14 areas are being released in the Carnarvon Basin, with eight areas located in the Dampier Sub-basin, three small blocks in the Rankin Platform and three large blocks on the Northern Exmouth Plateau (these are considered a deep water frontier). In the south, six large areas are on offer in the Ceduna Sub-basin and five areas of varying sizes are being released in the Otway Basin, including a deep water frontier offshore Victoria. The special release areas are located in the Petrel Sub-basin, Bonaparte Basin offshore Northern Territory, and encompass the Turtle/Barnett oil discoveries. The 2009 offshore acreage release offers a wide variety of block sizes in shallow as well as deep water environments. Area selection has been undertaken in consultation with industry, the states and Territory. This year’s acreage release caters for the whole gamut of exploration companies given that many areas are close to existing infrastructure while others are located in frontier offshore regions. As part of Geoscience Australia’s Offshore Energy Security Program, new data has been acquired in offshore frontier regions and have yielded encouraging insights into the hydrocarbon prospectivity of the Ceduna-Sub-basin.

On 12 May 1988 amendments to the Queensland Petroleum Act of 1923 came into force. These empower the Governor- in- Council to appoint a Pipelines Tribunal to inquire into the operations of any existing or proposed pipeline. The Act now affirms the existence of the Secretary of Mines as a Corporation which can undertake all the aspects of an oil company from exploration to distribution of refined products. In particular, this corporation now has the sole right to construct and operate any pipeline in Queensland which extends beyond the boundaries of a lease. There was little or no dialogue with industry prior to the proclamation of these amendments.In comparison with the Petroleum Acts of South Australia, Western Australia and the Northern Territory, the Queensland Petroleum Act contains many areas subject to ministerial discretion or which are no longer relevant to present- day administrative practices. The Queensland Government's proposal to issue a green paper discussing amendments to the Act, based on submissions from interested parties, is welcomed since it is in the interests of management of the exploratory oil industry to strive for uniformity of administration in each state.

The distribution and conservation status of the Black-footed Rock-wallaby Petrogale lateralis (MacDonnell Ranges race), in the Northern Territory were investigated to complement previous surveys in adjoining areas of Western Australia and South Australia. Historical data were collated and compared with recent biological survey results obtained between 1870 and 1999. From a total of 469 records, 400 were collated for the period 1975-1999. The species occurs over ten biogeographic regions, principally within the MacDonnell Ranges bioregion, but with many populations in the Burt Plain and Great Sandy Desert bioregions. It is widely distributed through pastoral, Aboriginal, conservation and urban land and, at present, retains much the same distribution as concluded from early records. Thirteen conservation areas and 30 pastoral leases currently support populations of the species. An unknown number of animals live in and about Alice Springs. Only two National Parks, the West MacDonnells and Finke Gorge, are considered large and diverse enough to ensure the long-term survival of P. lateralis. Measures of abundance are not available but numbers of animals in conservation areas are perceived to have remained stable or to have increased over the past 20 years. Surveys undertaken during the period 1975-1999 indicate that P. lateralis have disappeared from 21 of 400 sites. Petrogale lateralis were present on all major rock types, including many granite outcrops. They were most widespread and apparently abundant on major quartzite ranges such as the MacDonnells where steep cliff faces, gorges, scree slopes and fire shadow areas are common. The wide distribution of P. lateralis in the Northern Territory in comparison to other states may be due to a variety of factors: widespread, relatively contiguous and variable habitat, occupation of country north of the core distribution of Oryctolagus cuniculus and of Vulpes vulpes, the inability of Capra hircus to persist and thus to compete in rocky range habitat, and a government 1080 poisoning programme for Canis lupus dingo on pastoral land. There is however, concern for the survival of some populations on many small ranges and rock outcrops on the fringes of its known distribution where recent observations indicate that numbers of animals are low.
