Woodleigh, Southern Carnarvon Basin, Western Australia: history of discovery, Late Devonian age, and geophysical and morphometric evidence for a 120 km-diameter impact structure

The discovery of the Woodleigh impact structure, first identified by R. P. lasky, bears a number of parallels with that of the Chlcxulub impact structure of K-T boundary age, underpinning complications inherent in the study of buried impact structures by geophysical techniques and drilling. Questions raised in connection with the diameter of the Woodleigh impact structure reflect uncertainties in criteria used to define original crater sizes in eroded and buried impact structures as well as limits on the geological controls at Woodleigh. The truncation of the regional Ajona - Wandagee gravity ridges by the outer aureole of the Woodleigh structure, a superposed arcuate magnetic anomaly along the eastern part of the structure, seismic-reflection data indicating a central > 37 km-diameter dome, correlation of fault patterns between Woodleigh and less-deeply eroded impact structures (Ries crater, Chesapeake Bay), and morphometric estimates all indicate a final diameter of 120 km. At Woodleigh, pre-hydrothermal shock-induced melting and diaplectic transformations are heavily masked by pervasive alteration of the shocked gneisses to montmorillonite-dominated clays, accounting for the high MgO and low K2O of cryptocrystalline components. The possible contamination of sub-crater levels of the Woodlelgh impact structure by meteoritic components, suggested by high Ni, Co, Cr, Ni/ Co and Ni/Cr ratios, requires further siderophile element analyses of vein materials. Although stratigraphic age constraints on the impact event are broad (post-Middle Devonian to pre-Early Jurassic) high-temperature (200-250 degrees C) pervasive hydrothermal activity dated by K-Ar isotopes of illite - smectite indicates an age of 359 +/- 4 Ma. To date neither Late Devonian crater fill, nor impact ejecta fallout units have been identified, although metallic meteoritic ablation spherules of a similar age have been found in the Conning Basin.

Re-imagining the museum: beyond the mausoleum

Through a range of case- studies, including studies from the UK, North America and Australia, this book moves away from the idea that museums are always "conservative" to suggest they have a long history of engaging with popular culture and addressing a variety of audiences. Andrea Whitcomb argues that museums are key mediators between high and popular culture and between government, media practitioners, cultural policy-makers and museums professionals. The book also analyses links between museums and the media, looks at the role of museums in cities and discusses the effects on museums of cultural policies.

History, status and future of Australia's native Sydney rock oyster industry

The Sydney rock oyster (Saccostrea glomerata) (SRO) is an oyster species that only occurs in estuaries along Australia's east coast. The SRO industry evolved from commercial gathering of oyster in the 1790s to a high production volume aquaculture industry in the 1970s. However, since the late 1970s the SRO industry has experienced a significant and continuous decline in production quantities and the industry's future commercial viably appears to be uncertain. The aim of this study was to review the history and the status of the SRO industry and to discuss the potential future prospects of this industry. This study summarised findings of the existing literature about the industry and defined development stages of the industry. Particular focus was put on the more recent development within the industry (1980s-present) which has not been covered adequately in the existing literature. The finding from this study revealed that major issues of the industry are linked to the management of prevailing diseases, the handling of water quality impairments from increasing coastal development, increasing competition from Australia's Pacific oyster (Crassostrea gigas) industry and the current socio-economic profile of the industry. The study also found that policy makers are currently confronted by the dilemma of saving a "dying art". Findings from this industry review may be vital for current and future fisheries managers and stakeholders as a basis for reviewing industry management and development strategies. This review may also be of interest for other aquaculture industries and fisheries who are dealing with similar challenges as the SRO industry.

Collecting diversity: the changing relationships between museums and culturally diverse communities

 Much of the focus of scholarship around cultural diversity and museums has taken the advent of multiculturalism in 1973 as a starting point. However, public museums also collected and exhibited items relating to culturally diverse communities from the time they were set up from the 1850s onwards, and my research seeks to produce a pre-history of contact between museums, governments and culturally diverse communities and individuals. By using objects and collections life histories from the time they enter the museum for collection and/ or exhibition purposes, I will analyse the way that these relationships have changed over time. One case study is of the gamelan Digul, parts of which are currently on display in the Australian Journeys gallery at the National Museum of Australia. The gamelan Digul first entered the collection of the National Museum of Victoria in 1946 when the museum accepted the donation of these musical instruments from Indonesians who were being deported after World War II. The gamelan remained in this collection until 1976 when it was deacessioned to Monash University who restored and exhibited it in 1999. The National Museum of Australia borrowed some instruments from the gamelan in 2009. Some of the questions I will explore are: What were the motivations behind the former political prisoners/ Indonesian citizens in donating the gamelan Digul to the National Museum of Victoria and why did the museum accept it? Why was the gamelan Digul deaccessioned to Monash University?  How does the display of these instruments at the NMA represent the historical Indonesian communities in Australia which was deported? 

Poverty in perception : a study of the twentieth-century prime ministers of Australia and New Zealand

Australia and New Zealand, as English-speaking nations with dominant white populations, present an ethnic anomaly not only in South East Asia, but also in the Southern Hemisphere. Colonised by predominantly workingclass British immigrants from the late eighteenth century, an ethnic and cultural connection grew between these two countries even though their indigenous populations and ecological environments were otherwise very different. Building a new life in Australia and New Zealand, the colonists shared similar historic perceptions of poverty – perceptions from their homelands that they did not want to see replicated in their new adopted countries. Dreams of a better life shaped their aspirations, self-identity and nationalistic outlook. By the twentieth century, national independence and self-government had replaced British colonial rule. The inveterate occurrence of poverty in Australia and New Zealand had created new local perspectives and different perceptions of, and about, poverty. This study analyses what relationship existed between the political directions adopted by the twentieth-century prime ministers of Australia and New Zealand and their perceptions of poverty. Using the existential phenomenological theory and methodology of Maurice Merleau-Ponty, the study adds to the body of knowledge about poverty in Australia and New Zealand by revealing the structure and origin of the poverty perceptions of the twentieth-century prime ministers.

Legacies of White Australia : race, culture and nation

The White Australia policy continues to haunt Australia. Here, leading Australian scholars provide an informed debate on the essential issues of race, identity and nation that will determine our attitudes to immigration, multiculturalism and Australian-Asian engagement in the twenty-first century.
