Some have contributed to the campaign—and the debate over its methods—as specialists, and others as enthusiasts. Some have voyaged to Antarctica, while others remained in Australia to guide, support and promote their efforts. The Australian Antarctic Division of the Department of the Environment and Water Resources prepared this plan to meet our Environment Protection and Biodiversity Conservation Act obligations arising from the National and Commonwealth Heritage listings of Mawson’s Huts Historic Site. While the Antarctic Territories Environment and Policy Section of the AAD is responsible for the contents of the plan, it acknowledges the direct and indirect contributions of this diverse community of interest. The source of much of the technical and contextual information and many of the policy directions was the Mawson’s Huts Historic Site Conservation Management Plan 2001, commissioned by the AAP Mawson’s Huts Foundation and prepared by Godden Mackay Logan Pty Ltd (under a steering committee of the AAD, Mawson’s Huts Foundation and the Australian Heritage Commission). The 2001 plan is not cited in every section of the text that draws on it, but the reader is advised to bear in mind that Godden Mackay Logan’s excellent work was a key source. This plan was improved and enriched by several reviewers. An exposure draft was circulated to heritage experts and organisations with a known interest in the conservation and management of Mawson’s Huts from 27 March to 18 May 2007. The AAD was grateful for comments in this phase from Mr Duncan Marshall (heritage consultant, ACT), Dr Estelle Lazer (archaeologist, University of Sydney), Dr Ian Godfrey (materials conservator, WA Museum), the Mawson’s Huts Foundation (via Mr Robert Easther, expedition manager), Mr Michael Staples (heritage carpenter) and the ANARE Club Council (via Mr Bill Burch). The Heritage Division of the Department of the Environment and Water Resources reviewed a revised draft in June 2007, and the version formally released for public comment from 25 July to 27 August 2007 incorporated responses to the Heritage Division’s suggestions. The AAD received correspondence from several parties during the public comment period expressing support for the conservation of the huts— and none arguing against conserving the site. The AAD’s editorial committee was grateful for specific suggestions from Mr Duncan Marshall (heritage consultant, ACT) and Godden Mackay Logan Pty Ltd (heritage consultants, NSW―via Prof Richard Mackay). The AAD wishes to thank the State Library of New South Wales for granting the permission to use photographs from its AAE collection, and the photographers from recent conservation expeditions, whose images also illustrate this plan. iv Preface Mawson’s Huts Historic Site is a national treasure. As the first base for Australia’s scientific and geographical discovery of Antarctica, it is the birthplace of and the forerunner to the work now carried out and supported by the Australian Antarctic Division. The Australasian Antarctic Expedition (AAE) of 1911 to 1914 was the first large-scale scientific inquiry after Federation. AAE expeditioners braved the isolation and severe climate to gather valuable scientific and geographical information. Two of their comrades perished in the attempt. The AAE made the first radio communication from Antarctica, and carried the first aeroplane to the Antarctic. Today, the Australian Antarctic Division is establishing a jet air service between Australia and Antarctica–the last two continents to be linked by air. As we approach the centenary of Mawson’s inspirational expedition, we need plans in place to preserve the sense of what the site was like when the AAE abandoned their huts to the elements in December 1913, while also allowing an appreciation of the powerful effects of a hundred years of exposure in the world’s windiest place at sea level. We also need to find ways to encourage Australians who may never set foot on Antarctica to appreciate the experiences and achievements of the men who lived there. To date, the Australian Antarctic Division has worked closely with the Mawson’s Huts Foundation and other bodies interested in the site and its story. We have provided funding, advice, staff and in-kind support, and facilitated access to enable conservation work. We also supported the development of the 2001 Conservation Management Plan commissioned by the Foundation. During the life of that plan, recognition of the outstanding significance of the site has expanded, and major conservation works were completed. The site gained the highest level of Australian recognition, becoming a National Heritage place and a Commonwealth Heritage place. International protection was bolstered: the site is now contained in an Antarctic Specially Protected Area, and an Antarctic Specially Managed Area. Major structural conservation work is now largely complete. Thanks to innovative techniques, the main buildings are stabilised. This gives us the confidence to embark on a new phase, of monitoring and addressing the objects scattered in and around the huts. This management plan meets our obligations from the new heritage listings, is consistent with Antarctic Treaty requirements, and will foster a new focus — on artefacts — in the lead-up to the AAE centenary. I commit the Australian Antarctic Division to working with all interested organisations to achieve the goals identified in this blueprint, to protect and manage what is surely the jewel in the crown of Australia’s Antarctic heritage.
