When the
Australian Government decided in the early 1950s to set aside the
Emu Field and
Maralinga in the area for
British nuclear testing, the community at Ooldea was forcibly removed from the land and resettled further south at
Yalata, in 1952. Road blocks and soldiers barred any return. Yalata, bordering on the
Nullarbor Plain offered a totally different
ecological environment; in place of the
spinifex plains to the north, the Maralinga Tjaruta people found an arid stone plain, with poor thin soil and a powdery limestone that kicked up a grey dust when disturbed. Their word for "grey", namely
tjilpi also signified the greying elders of a tribe, and the Aboriginal residents of Yalata called the new area
parna tjilpi, the "grey earth/ground", suggesting that their forced relocation to Yalata went concomitantly with ageing towards death. Between 1956 and 1957, seven atomic bombs were exploded on Maralinga land. In further minor trials from 1957 to 1962,
plutonium was dispersed widely over much of the area. Compensation in 1993 of was determined after three elders flew to London and presented samples of the contaminated soil in London in October 1991. In 1962, the long-serving
Premier of South Australia,
Sir Thomas Playford, made a promise that their traditional lands would be restored to the people displaced at Yalata sometime in the future. Under the administration of his successor
Frank Walsh, short two-week long bush trips were permitted, enabling them to re-connect with their traditional lifestyles. As negotiations got underway in the 1980s, the Indigenous peoples started setting up
outstations near their original lands. With the passage of the
Maralinga Tjarutja Land Rights Act 1984 under Premier
John Bannon's government, the Maralinga Tjarutja secured
freehold title in 1984, and the right to developmental funds from the State and Federal governments. They completed a move back into the area, to a new community called
Oak Valley in March 1985. Under an agreement between the governments of the United Kingdom and Australia in 1995, efforts were made to clean up the Maralinga site, being completed in 1995. Tonnes of soil and debris contaminated with
plutonium and
uranium were buried in two trenches about deep. The effectiveness of the cleanup has been disputed on a number of occasions. In 2003 South Australian Premier
Mike Rann opened a new school costing at
Oak Valley. The new school replaced two caravans with no running water or air-conditioning, a facility that had been described as the "worst school in Australia". In May 2004, following the passage of special legislation, Rann fulfilled a pledge he had made to Maralinga leader
Archie Barton as Aboriginal Affairs Minister in 1991, by handing back title to of land to the Maralinga Tjarutja and
Pila Nguru people. The land, north-west of Adelaide and abutting the
Western Australia border, is now known as
Mamungari Conservation Park. It includes the
Serpentine Lakes and was the largest land return since Premier
John Bannon's hand over of Maralinga lands in 1984. The returned lands included the sacred
Ooldea area, which also included the site of
Daisy Bates' mission camp. In 2014, the last part of the land remaining in the
Woomera Prohibited Area, known as "Section 400", was excised and returned to free access. ==Maralinga Tjarutja Council==
