  • Delving Into Australia's Remote Art Centres While Travelling by Rail And
    Delving into Australia’s remote art centres while travelling by rail and sea offers a unique opportunity to experience stunning landscapes ar from urban civilisation, in the Northern Territory a nomadic connection and buy unique artworks at between land and life itself is fundamental for indigenous Australians. source. By Fiona Harper. Surviving 40,000-odd years in some of Australia’s most remote lands, ancient stories, songs and dance passed down through the generations are finding their way into the mainstream via contemporary art galleries. Art Despite, or perhaps because of, its far-flung location, Arnhem Land in particular is a breeding ground of artistic creativity. FMulti-award-winning musicians Yothu Yindi, with their powerful blend of indigenous and modern music, hail from Yirrkala in northeast Arnhem Land. in its Their name translates to “mother and child”, depicting a kinship connection that Yolgnu people have with each other, whether freshwater or saltwater people. This yothu yindi belief underpins much of the creative works coming from Arnhem Land. Singer Geoffrey Gurrumul Yunupingu, from Elcho Island, blind since birth, captures this emotive spirit of country with his high tenor voice. His appearance on the cover of Rolling Stone magazine last year did much to propel Place Arnhem Land culture into the mainstream. But it is the artworks emerging from this remote land that are capturing most attention among collectors and galleries across the globe. Places such as Maningrida, Yirrkala, Elcho and Melville Islands all have thriving art communities supported by community art centres with tendrils that reach far and wide. Most have comprehensive online galleries, though one-dimensional photographs rarely show the exquisite nature of artworks.

Islands are increasingly used to protect endangered populations from the negative impacts 23 of invasive species. Quarantine efforts are particularly likely to be undervalued in 24 circumstances where a failure incurs non-economic costs. One approach to ascribe value 25 to such efforts is by modeling the expense of restoring a system to its former state.

(photo: Kym Brennan) 11 Summary Recently, the northern quell Dasyurus ha/lucatus has suffered widespread and rapid decline across its mainland range because of its susceptibility to poisoning by the invading cane toad Bufo marinus. Island populations may now offer the greatest long-term security for the northern quell. Here, we collate all available information on the occurrence of northern quells on Northern Territory islands, and report on two surveys to previously-unsampled sets of islands. We list 233 islands >20 ha in the Northern Territory. Northern quells are known to occur naturally on 10 of these islands, known to be absent from 58 islands, and probably absent (on the basis of lack of reports from inhabited or visited islands) from a further 35 islands. This set of islands is an unrepresentative sample of the total island pool, with larger more rugged islands more likely to have been sampled. The pattern of occurrence of quells on Northern Territory islands was examined with generalised linear modelling, with one model including only definite present and absent records, and the other model also including probable absences.

  • A Strategy for the Conservation of Threatened Species and Threatened Ecological Communities in Kakadu National Park | 2014-2024
    A strategy for the conservation of threatened species and threatened ecological communities in Kakadu National Park | 2014-2024 By J.C.Z. Woinarski and S. Winderlich - October 2014 Vision: Kakadu National Park will be celebrated as a place in which management provides for the effective conservation of threatened species. Acknowledgements This strategy has been commissioned by Kakadu National Park. It responds to the interest and concerns of the Kakadu Board of Management, traditional owners, staff in Kakadu National Park and Parks Australia, and the Kakadu Research Advisory Committee. The strategy will be progressively implemented by Kakadu National Park over 10 years. Some recommendations are already being implemented, while others require further planning and consultation. This strategy was developed with the support of the North Australian Hub of the National Environmental Research Program. Michael Douglas oversaw the management and production of this strategy, and Jaana Dielenberg and Carli Piltz its layout and production. Vanessa Adams, Nick Dexter, Sam Flakus and Alaric Fisher provided helpful comments on earlier drafts. The strategy was initiated at a workshop held in Kakadu in March 2013, with the attendance and significant inputs from Alan Andersen, Roy Anderson, Frederick Baird, Mathias Baird, Josh Bean, Ryan Barrowei, Stuart Blanch, Mary Blyth, Roman Chaloupka, Peter Christophersen, Peter Cooke, Anthony Contarino, Ian Cowie, Samantha Deegan, Mark Ellis, Katie Elsley, Alaric Fisher, Stephen Garnett, Cherie Gellert, Graeme Gillespie, Louise Harrison, Michael Hammer, Fred Hunter, Jenny Hunter, Craig Ingram, Sarah Kerin, Peter Kyne, Violet Lawson, Jeff Lee, Sandra McGregor, Dan McIntyre, Andrew McPhee, Brendan Mee, Greg Miles, Ian Morris, Gleeson Nabulwad, Grant Nayinggul, Connie Nayinggul, Anne O’Dea, Gabrielle O’Loughlin, Margaret Rawlinson, Buck Salau, Ben Tyler, Berribob Watson, Sean Webster, Dion Wedd, Kathy Wilson and Dean Yibarbuk.

Results: The results from a 2015 vacuum drilling program, completed on EL3350, in the centre of Howard Island were disappointing and failed to intersect significant bauxite. Conclusions: Due to the poor results from drilling in EL3350 and given the proximity and analogous geological settings of the two areas, Alcoa of Australia Limited believes that EL29848 holds little potential to host an economic bauxite deposit. EL29848 will be surrendered. Copyright Statement: This document and its content are the copyright of Alcoa of Australia Limited.
