1948 American-Australian Scientific Expedition to Arnhem Land

The American-Australian Scientific Expedition to Arnhem Land (also known as the Arnhem Land Expedition) remains one of the most significant, most ambitious and least understood expeditions. Commenced in February 1948, it was one of the largest scientific expeditions to have taken place in Australia and was conducted by a team of Australian and American researchers and support staff.

Background
A number of publications, including H. H. Finlayson’s The Red Centre: Man and Beast in the Heart of Australia (1935), and Walkabout travel and geographical magazine (1934–1974), revised Australians' concept of 'The Centre" from the picture presented in J. W. Gregory's The Dead Heart of Australia (1909).

Leader-to-be of the Arnhem Land Expedition, Charles P. Mountford and his wife Bessie travelled over four months from Ernabella to Uluru in 1940, with Lauri Sheard and skilled cameleer Tommy Dodd undertaking an extensive study of the art and mythology surrounding Uluru and Kata Tjuta. The results of this endeavour were showcased through photographic exhibitions and a prize-winning film created in 1940, which subsequently became the foundation for Mountford's first publication Brown Men and Red Sand (1948), and his 1945 lecture tour in the United States which paved the way for the establishment of the American-Australian Scientific Expedition to Arnhem Land.

The American-Australian Scientific Expedition to Arnhem Land, known as the 'last of the big expeditions,' was not primarily about terrestrial exploration but aimed to advance knowledge. It focused on studying the natural environment and Aboriginal inhabitants. Taking place after World War II, it symbolized transformations in Australia and globally. The expedition served diplomatic objectives by showcasing collaboration between the United States and Australia, enhancing their trans-Pacific relationship. The mission's public face hid negotiations that would shape this relationship for the 20th century. The expedition garnered domestic support due to Australia's pro-American sentiments after WWII, as the nation adjusted to post-war changes and Britain's reduced global influence. The subsequent signing of the ANZUS Treaty by Robert Menzies continued this collaborative trajectory.

The expedition
Seventeen individuals, both men and women, journeyed across the remote region known as Arnhem Land in northern Australia for nine months. From varying disciplinary perspectives, and under the guidance of expedition leader Charles Mountford, they investigated the Indigenous populations and the environment of Arnhem Land. In addition to an ethnographer, archaeologist, photographer, and filmmaker, the expedition included a botanist, a mammalogist, an ichthyologist, an ornithologist, and a team of medical and nutritional scientists.

Their first base camp was Groote Eylandt in the Gulf of Carpentaria. Three months later they moved to Yirrkala on the Gove Peninsula and three months following that to Oenpelli (now Gunbalanya) in west Arnhem Land. The journey involved the collaboration of different sponsors and partners (among them the National Geographic Society, the Smithsonian Institution, and various agencies of the Commonwealth of Australia).

A Bulletin article in 1956 noted that the scientists collected 13,500 plants, 30,000 fish, 850 birds, 460 animals, thousands of implements, amounting to twenty-five tons, and photographed and filmed in colour and black-and-white and made tracings of cave-paintings from Chasm Island, Groote Eylandt and Oenpelli. The Australian Broadcasting Commission promoted the Expedition in its ABC Weekly magazine by appealing to readers curiosity about "...a fish that looks exactly like a leaf, a multi-coloured praying mantis, intricate string games the aborigines play, a fungus used to cure wounds..."

In the wake of the expedition came volumes of scientific publications. The legacy of the 1948 Arnhem Land Expedition is vast, complex, and, at times, contentious. Human remains collected by Setzler and later held by the Smithsonian Institution have since been repatriated to Gunbalanya.
