The Clarence-Moreton Basin covers an area of some 28 000 km2 in north-eastern New South Wales and south-eastern Queensland. The basin is relatively unexplored, with a well density in New South Wales of one per 1600 km2. Since 1980, Endeavour Resources and its co-venturers have pursued an active exploration programme which has resulted in the recognition of significant petroleum potential in the New South Wales portion of the basin.Previous studies indicated that the Upper Triassic to Lower Cretaceous Clarence-Moreton Basin sequence in general, lacked suitable reservoirs and had poor source- rock potential. While exinite rich, oil-prone source rocks were recognised in the Middle Jurassic Walloon Coal Measures, they were considered immature for oil generation. Moreover, during the 1960's the basin acquired a reputation as an area where seismic records were of poor quality.These ideas are now challenged following the results of a new round of exploration which commenced in the New South Wales portion of the basin in 1980. This exploration has involved the acquisition of over 1000 km of multifold seismic data, the reprocessing of some 200 km of existing single fold data, and the drilling of one wildcat well. Over twenty large structural leads have been identified, involving trapping mechanisms ranging from simple drape to antithetic and synthetic fault blocks associated with normal and reverse fault dependent and independent closures.The primary exploration targets in the Clarence- Moreton Basin sequence are Lower Jurassic sediments comprising a thick, porous and permeable sandstone unit in the Bundamba Group, and channel and point-bar sands in the Marburg Formation. Source rocks in these and the underlying Triassic coal measures are gas-prone and lie at maturity levels compatible with gas generation. In contrast, it was established from the results of Shannon 1 that the Walloon Coal Measures are mature for oil generation and this maturity regime is now considered to be applicable to most of the basin in New South Wales.A consideration of reservoir and source rock distribution, together with structural trends across the basin in Petroleum Exploration Licences 258 and 259, has led to the identification of three prospective fairways, two of which involve shallow oil plays. Exploration of these fairways is currently the focus of an ongoing programme of further seismic data acquisition and drilling.

Field trials were carried out in the Brunswick River district of New South Wales from 1971 to 1975 to evaluate insecticides against dieldrin-resistant banana weevil borer, Cosmopolites sordidus Germar. Effective control was obtained by spraying the bases of plants and surrounding soil to a radius of 30 cm in spring and autumn with pirimiphos-ethyl and chlorpyrifos emulsions at 2.24 kg active ingredient ha-1 (1.12g per plant) per application. Chlordecone dust, pirimiphos-ethyl granules and chlorpyrifos powder sprinkled by hand at 2.8 kg ha-1 a.i. (1.42 g per plant) per application also gave effective control and could be used where water is unavailable.

Field trials investigating ultra-low volume applications of undiluted technical maldison by aircraft against dense populations of Phaulacridium vittatum Sj�stedt (wingless grasshopper) are described. In February 1965 an application rate of 8.2 fl oz an acre gave 90-95 per cent reduction of grasshopper populations on a property on the northern tablelands of New South Wales. A further trial in November 1965, using rates of 4.6 and 5.6 fl oz per acre, gave similar results for each rate-70 per cent reduction of the population one day after spraying, rising to 80-85 per cent within eleven days. Some aspects of a large aerial spraying campaign conducted from October to December 1965 are also described. More than 150,000 acres were treated with maldison at the rate of 6.3 fl oz an acre. Detailed observations of the campaign spraying were made on a single property as well as general surveys of the whole treated area. A minimum application rate of 8.0 fl oz maldison an acre is suggested for normal field usage against P. vitiatum.

Cumulative day-degrees, total rainfall and the mean daily values for evaporation rate, maximum temperature, minimum temperature and radiation for a period of 200 days from 1 October to 18 April were used to characterize the climates of cotton-growing seasons at Narrabri (30�S.), N.S.W. Yields (expressed as percentages of standards) of some cultivars included in field trials in cotton-growing districts of New South Wales, were then regressed on these climatic indices. In a number of cases strong, significant linear associations of performance with one or more of the indices were found. Such cultivars were either more or less advantaged by warm, dry conditions than the standards, and vice versa for cool, wet conditions. The implications of these results in studies of genotype x environmental interaction are discussed.

The petroleum industry in Australia is at the centre of a web of complex laws. In addition to the legislation under which petroleum exploration and production tenements are granted there is a multiplicity of statutes and regulations, Commonwealth and State, which have a direct bearing on the conduct of those involved in exploring for or exploiting Australia's petroleum reserves. For example, the level of participation by foreigners is governed by the Commonwealth Foreign Investment Guidelines and the Foreign Takeovers Act 1975; the Commonwealth has control over the export of petroleum under the Customs (Prohibited Exports) Regulations and domestic markets are subject to the operation of the Crude Oil Allocation Scheme. The Commonwealth continues to have the right to regulate the transfer of funds to and from Australia under the Banking (Foreign Exchange) Regulations. Certain States such as South Australia and New South Wales have their own foreign investment guidelines.Not only this, there are revenue laws which govern very much the way in which petroleum projects are organised, interests transferred and otherwise dealt with and finance made available, such as State stamp duty legislation, Commonwealth income tax laws, and Commonwealth legislation imposing registration fees on dealings in exploration permits and production licences. A new tax, Resource Rent Tax, is to be introduced.Then there are laws which have an indirect bearing on petroleum activities such as the Companies Code which, in addition to governing the administration and organisation of companies, controls the way funds can be raised.The statutory and regulatory framework is only part of the picture. The rights and obligations of participants in petroleum projects as between themselves are almost always set out in a joint venture or joint operating agreement, the combination between the participants being known as an unincorporated joint venture. This form of business organisation is not a partnership; it is not the creature of legislation. Indeed it has been rarely referred to in Acts of Parliament. Problems arising under the joint venture agreement will be considered against the backdrop of the general law which unfortunately has seldom been called upon to resolve disputes between participants in joint ventures. An illustration of one of these rare instances is Brian Pty Ltd v United Dominions Corporation Ltd (1983), where the New South Wales Court of Appeal considered the fiduciary relationship of joint venturers.Despite this legislative and regulatory' backdrop and the uncertainties as to the true effect of joint venture agreements, the industry up until quite recently has survived with little litigation. This is no longer the case. Recent and pending litigation shows that there is no reluctance on the part of participants to take their disputes to court, often at great expense and with unfortunate results for previously close relationships. It must now be said that money spent to achieve proper and clear agreement on organisational and legal matters at the earliest stage of a project is money just as well spent as that on drilling and other operational activities.

Soil is a valuable natural resource. In the state of New South Wales, Australia, the governance of soil has evolved since Federation in 1901. Following rapid agricultural development, and in the face of widespread soil degradation, the establishment of the Soil Conservation Service marked a turning point in the management of soil. Throughout the 20th century, advances in knowledge were translated into evolving governance frameworks that were largely reactionary but saw progressive reforms such as water pollution legislation and case studies of catchment-scale land and vegetation management. In the 21st century, significant reforms have embedded sustainable use of agricultural soils within catchment- and landscape-scale legislative and institutional frameworks. What is clear, however, is that a multitude of governance strategies and models are utilised in NSW. No single governance model is applicable to all situations because it is necessary to combine elements of several different mechanisms or instruments to achieve the most desired outcomes. Where an industry, such as the sugar industry, has taken ownership of an issue such as acid sulfate soil management, self-regulation has proven to be extremely effective. In the case of co-managing agricultural soils with other landuses, such as mining, petroleum exploration and urban development, regulation, compliance and enforcement mechanisms have been preferred. Institutional arrangements in the form of independent commissioners have also played a role. At the landscape or total catchment level, it is clear that a mix of mechanisms is required. Fundamental, however, to the successful evolution of soil governance is strategic investment in soil research and development that informs the ongoing productive use of agricultural landscapes while preventing land degradation or adverse environmental effects.

Nine populations of Festuca arundinacea were grown in monoculture in two field trials on a black earth soil at Armidale, New South Wales during the period late 1967 to early 1970. There were four cutting treatments (at 2, 4, 8 and 16 week intervals) in both experiments and in trial 2 half the plots were irrigated. Seasonal and total herbage production were determined for two periods, each of forty-eight weeks duration, and tillering patterns were studied in trial 2. Differences were demonstrated in the seasonal and total production of the populations. Those selected from temperate environments were higher yielding in spring, summer and autumn and produced more total dry matter during the year than did those from the Mediterranean region ; however, in both experiments these latter yielded some 10 kg ha-1 day-1 more than the temperate fescues during the second winter. One cultivar-Goar's fescue-performed in a manner intermediate between the temperate and Mediterranean populations. Total dry matter yields were reduced when the cutting interval was decreased; in contrast, tiller numbers increased with frequency of cutting. The results suggest considerable potential value of Mediterranean fescues for winter pasture production on the Northern Tablelands of New South Wales.
