The growth of international cooperation in the South Pacific region has been one of the remarkable developments in regional collaboration in the post-war era. During the past twelve years, three multilateral arrangements have come into existence bearing upon South Pacific affairs. These are the six-power South Pacific Commission (SPC), the three-power Australian—New Zealand—United States Mutual Security Treaty (known as ANZUS), and the Southeast Asian Collective Defense Treaty Organization (SEATO).

<p>Drawing from a body of leading literature on international and regional order, this thesis applies these concepts to the context of the South Pacific. Examining recent developments in the region through a framework of international order, and paying specific consideration to the regional operation of legitimacy, institutions and power dynamics, it seeks to shed light on the forces underpinning Fiji’s pursuit of regionalism through alternative institutional frameworks. In this, it concludes that Suva’s actions over the past decades constitute a challenge to the prevailing, Australian-New Zealand led regional order in the South Pacific, one that has occurred largely from a failure of Wellington and Canberra’s policymakers to appreciate first, changing power dynamics brought about by the entry of the “new players” into the region and second, divergent views throughout the region on what constitutes legitimate state conduct. Drawing these conclusions into the broader context of global international order, this thesis unpacks the distinct meanings and motivations underpinning these developments, and in doing so explores how regional developments have mirrored global trends in the American led liberal order, offering lessons for policymakers both within the region and beyond.</p>

This article is about the complicated relations between Norfolk Island located in the South Pacific and Australia that possesses the island as its ‘external territory’. Over the past century Australia and its tiny but strategically important possession have overcome many difficult moments, the most dramatic of which took place in 2015, when the Australian Parliament ended self-government on the island and put Norfolk under the laws of New South Wales thus making it part of Australia.

I am honoured by your invitation to present a Keynote Address at the 19th National Conference of the Australian Association of Special Education, and particularly pleased to have the opportunity to return to Darwin. I last visited here in 1990, to attend the UNESCO South East Asia and South Pacific Sub-Regional Conference “Education for All”. In 1991 I left Australia to undertake an AIDAB (now known as AusAID), project in the South Pacific region. So I have had the opportunity to view at first hand the progress that has been made towards the UNESCO goal of “Education for AH”, in a number of Pacific countries, during the past four years.

For the island nations of the South Pacific, the past few years has been a turbulent period in which existing political and economic structures have come under considerable strain and in some instances undergone substantial change. Nowhere has this been more dramatically seen than in the case of Fiji, where the incumbent government of seventeen years was defeated at the polls in April 1987 and the new government was overthrown by a military coup, the region's first, a month later. The French colony of New Caledonia, too, has witnessed considerable turmoil in recent years as the independence struggle of the indigenous Kanaks has led to sometimes violent confrontations. Elsewhere in the South Pacific violence has been less in evidence, but the pressure for change has been widespread.

Drawing on Professor Angelo’s work in relation to the patriation of law in Niue and Tokelau as an exemplar of best possible practice, Associate Professor Corrin argues in this article that the time has come for other small island jurisdictions to complete their own promised patriation projects. In her article Dr Corrin reviews the issues facing former British dependencies in assessing whether English law applies in their jurisdiction.  Dr Corrin concludes that the situation is problematic and that the interests of the rule of law would be better fulfilled by the introduction or the completion of patriation programmes. She reviews case law from a wide range of former dependencies which demonstrate the complexities of applying the reception rule and that of the confusion that can result.

The southern westerly wind belt (SWW) interacts with the Antarctic Circumpolar Current and strongly impacts the Southern Ocean carbon budget, and Antarctic ice-sheet dynamics across glacial–interglacial cycles. We investigated precipitation-driven sediment input changes to the Southeast Pacific off the southern margin of the Atacama Desert over the past one million years, revealing strong precession (19/23-ka) cycles. Our simulations with 2 ocean–atmosphere general circulation models suggest that observed cyclic rainfall changes are linked to meridional shifts in water vapor transport from the tropical Pacific toward the southern Atacama Desert. These changes reflect a precessional modulation of the split in the austral winter South Pacific jet stream. For precession maxima, we infer significantly enhanced rainfall in the southern Atacama Desert due to a stronger South Pacific split jet with enhanced subtropical/subpolar jets, and a weaker midlatitude jet. Conversely, we derive dry conditions in northern Chile related to reduced subtropical/subpolar jets and an enhanced midlatitude jet for precession minima. The presence of precessional cycles in the Pacific SWW, and lack thereof in other basins, indicate that orbital-scale changes of the SWW were not zonally homogeneous across the Southern Hemisphere, in contrast to the hemispherewide shifts of the SWW suggested for glacial terminations. The strengthening of the jet is unique to the South Pacific realm and might have affected winter-controlled changes in the mixed layer depth, the formation of intermediate water, and the buildup of sea-ice around Antarctica, with implications for the global overturning circulation and the oceanic storage of atmospheric CO2.

Purpose. The aim of the study consists in identifying the spatial-temporal features of interannual changes in the surface air temperature Ta, the sea surface temperature (SST) and the upper 1000-meter water layer temperature Tw in the extratropical zone of the South Pacific Ocean over the past four decades, which are manifested as a result of the planetary changes and a shift in the climatic regime at the turn of the XX–XXI centuries. Besides, the revealed features’ trends and their possible cause-and-effect relationships with the processes in the atmosphere and on the ocean surface are planned to be assessed. Methods and Results. Based on the Global Meteorological Network and Reanalysis data (NOAA), regional features and trends of the water and air temperature interannual fluctuations, and their relation to variations in the pressure and wind fields, intensity of the atmosphere action centers (AAC) and climatic indices (CI) over the past 4 decades have been determined. Applied were the methods of the cluster, correlation and regression analysis, as well as the apparatus of empirical orthogonal functions (EOF). The positive trends in changes of the Ta and SST fields are manifested mainly in the northwestern part of the region, where they are statistically significant and reach their maximum 0.4–0.6°C over 10 years in the Tasman Sea region and to the northeast of New Zealand. The water areas with minimal, negative or insignificant values of the air and water temperature trends are located on the southern and eastern peripheries of the water area under study – in the areas of influence of cold currents. Over the entire investigated water area, the trends in the mean annual SST and Ta were ~ 0.04–0.06°C/10 years that are 2–3 times less than those in the subarctic region of the North Pacific Ocean. The features of spatial-temporal variability of the water temperature trends at different horizons differ significantly from the characteristics of the SST trends. The trends’ spatial distribution is already transformed within the upper 200-m layer; and deeper, maximums of this value are observed in the southeastern part of the water area. Conclusions. The results obtained made it possible to characterize the degree of heterogeneity of response of the atmosphere surface layer, SST and vertical distribution of Tw in the extratropical zone of the South Pacific to the ongoing global changes, to identify the isolated areas, to estimate quantitatively the warming rate in these water areas, and to compare these estimates with those of the other regions in the Pacific Ocean. It is shown that the individual phases of alternation of the warm and cold periods in the interannual temperature variation are consistent with the changes of the regional CI and the AAC state; this fact emphasizes the inhomogeneous nature of these processes in space and time.

The People's Republic of China in the past decades has experienced dynamic and accelerative growth. Its activities the world over, particularly in the South Pacific is a projection of its foreign policy as well as its economic and political ambition. While its growing power remains progressive, the dominant explanation for this trend is its desire to attain the hegemonic status that is unrivalled.
