Selection Neither the Montebello Islands nor Emu Field were considered suitable as permanent test sites, although Montebello was used again in 1956 for
Operation Mosaic. Montebello could be accessed only by sea, and Emu Field had problems with its water supply and dust storms. The British Government's preferred permanent test site remained the
Nevada Test Site in the United States, but by 1953 it was no closer to securing access to it than it had been in 1950. When
William Penney, the Chief Superintendent Armament Research, visited South Australia in October 1952, he gave the Australian Government a summary of the requirements of a permanent test site. In May 1953, the UK
Chiefs of Staff Committee were advised that one was needed. They delegated the task of finding one to
Air Marshal Sir
Thomas Elmhirst, the chairman of the Totem Executive (Totex), which had been formed in the UK to coordinate the Operation Totem tests. He wrote to
J. E. S. Stevens, the
permanent secretary of the Australian Department of Supply, and the chairman of the Totem Panel that coordinated the Australian contribution to Operation Totem, and outlined the requirements of a permanent test site, which were: • A radius free of human habitation; • Road and rail communications to a port; • A nearby airport; • A tolerable climate for staff and visitors; • Low rainfall; • Predictable weather conditions; • Winds that would carry the fallout safely away from inhabited areas; and • Reasonably flat terrain; • Isolation for security. Elmhirst suggested that a site might be found in
Groote Eylandt in the
Gulf of Carpentaria or north of Emu Field, where it could be connected by road and rail to
Oodnadatta, and where water could more easily be found than at Emu Field. Stevens rated both as unsuitable; Groote Eylandt was wooded and rocky, with a pronounced rainy season, no port facilities, and a long way from the nearest major settlements of
Darwin and
Cairns; while the area north of Emu Field had scarce water, few roads and was on the axis of the
Long Range Weapons Establishment (LRWE), which meant that there would be a competing claim on the use of the area.
Group Captain George Pither conducted an aerial survey of the area north of the
Trans-Australian Railway between
Ooldea and
Cook, South Australia. This was followed by a ground reconnaissance in four
land rovers and two four-wheel drive trucks by Pither,
Wing Commander Kevin Connolly, Frank Beavis (an expert in soil chemistry),
Len Beadell and the two truck drivers. An area was found north of Ooldea, and a temporary airstrip was created in two days by land rovers dragging a length of railway line to level it, where Penney,
Flight Lieutenant Charles Taplin and Chief Scientist
Alan Butement landed in a
Bristol Freighter on 17 October 1953, two days after the Totem 1 test at Emu Field. The site, initially known as X.300, was nowhere near as good as the Nevada Test Site, with its excellent communications, but was considered acceptable. It was flat and dry, but not affected by dust storms like Emu Field, and the geologists were confident that the desired per annum could be obtained by boring. Rainwater tanks were recommended, and it was estimated that if
bore water could not be obtained, a water pipeline could be laid to bring water from
Port Augusta. This was estimated to cost
AU £53,000 to construct and AU £50,000 per annum to operate. On 25 November, Butement officially named the X.300 site "Maralinga" in a meeting at the Department of Supply. This was an Aboriginal word meaning "thunder", but not in the
Western Desert language of the local people; it came from Garik, an extinct language originally spoken around
Port Essington in the
Northern Territory. On 2 August 1954, the
High Commissioner of the United Kingdom to Australia lodged a formal request for a permanent proving ground for multiple series of nuclear tests expected to be conducted over the course of the next decade and a preliminary agreement between the Australian and British Governments was reached on 26 August. A mission consisting of six officials and scientists headed by J. M. Wilson, the under-secretary of the UK
Ministry of Supply (MoS) visited Australia in December to evaluate the Maralinga site, and reported that it was excellent. The new site was officially announced by Beale on 4 April 1955, and the
Australian Cabinet gave its assent on 4 May. A formal Memorandum of Arrangements for use of Maralinga was signed on 7 March 1956. It specified that the site would be available for ten years; that no thermonuclear tests would be carried out; that the British Government would be liable for all claims of death or injury to people or damage to property as a result of the tests, except those to British Government personnel; that Australian concurrence would be required before any test could be carried out; and that the Australian authorities would be kept fully informed. Maralinga was to be developed as a joint facility, co-funded by the British and Australian Governments. The range covered , with a test area. With savings arising from the relocation of buildings, stores and equipment from Emu Field taken into account, the cost of developing Maralinga as a permanent site was estimated to cost AU £1.9 million, compared with AU £3.6 million for Emu Field. The British Government welcomed Australian financial assistance, and Australian participation avoided the embarrassment that would have come from building a UK base on Australian soil. On the other hand, it was recognised that Australian participation would likely mean that the Australians would demand access to even more information than in Operation Totem. This had implications for Britain's relationship with the United States. Sharing information with the Australians would make it harder to secure Britain's ultimate goal, of restoring the wartime nuclear
Special Relationship with the United States, and gaining access to information pertaining to the design and manufacture of US nuclear weapons.
Development A railhead and a quarry were established at
Watson, about west of Ooldea, and Beadell's bush track from Watson to Emu became the main
line of communications for the project. It ran north to the edge of the
Nullarbor Plain, then over sand hills and the Leisler Range, a
mallee,
spinifex and
quandong covered escarpment, rising to an altitude of . Range headquarters, known as The Village, and an airstrip with a runway were built near the peg. The track continued north over scrub-cover sand hills to the Teitkins Plain. There at a point that came to be known as Roadside, a control point was established for entry to the forward area where bombs were detonated. The UK MoS engaged a firm of British engineering consultants,
Sir Alexander Gibb & Partners, to design the test facilities and supervise their construction. The work was carried out by the Kwinana Construction Group (KCG) under a
cost-plus contract. It had just finished the construction of an oil refinery near
Fremantle, and it was hoped that it could move on to the new venture immediately, but the delay in obtaining Cabinet's approval meant that work could not start until mid-1955, by which time most of its work force had dispersed. The need to create a new work force caused a cascading series of delays. Assembling a labour force of 1,000 from scratch in such a remote location proved difficult, even when KCG was offering wages as high as AU £40 a week (). The Australian Government elected to create a tri-service task force to construct the test installations. The Australian Army's Engineer in Chief,
Brigadier Ronald McNicoll designated Major
Owen Magee, the Commander,
Royal Australian Engineers,
Western Command, to lead this task force. He joined a party headed by
Lieutenant Colonel John Blomfield, the MoS Atomic Weapons representative in Australia, on a site inspection, and then flew to the
Atomic Weapons Research Establishment (AWRE) at
Aldermaston in the UK in a
Royal Air Force (RAF)
Handley Page Hastings to review the plans. These were still incomplete, but it gave Magee sufficient information to prepare estimates of the labour and equipment that would be required. The job involved the erection of towers, siting of instrument mounts, grading of of tracks, laying control cables and power lines, and construction of bunkers and other facilities dispersed over an area of but sited to within an accuracy of . The work force could not be fully assembled before 1 March 1956, but the facilities had to be ready for use by the end of July. Magee provided Bloomfield with a list of required stores and equipment. These ranged from timber and nails to drafting gear and two wagon drills. The task force, which began assembling in February 1956, included a section from the
Royal Australian Survey Corps, a troop of the 7th Field Squadron, detachments from the
Royal Australian Navy (RAN) and
Royal Australian Air Force (RAAF), and a civilian from the
Department of Works and Housing. Their first task was establishing their own camp, with tents, showers and toilets. A team from the South Australian Department of Mines sank a series of bores to provide water. Like that at Emu Field, the bore water was
brackish. Two Army skid-mounted Cleaver-Brooks
thermocompression distillation units provided water for drinking and cooking. Work on the facilities themselves got off to a slow start, as KCG was running behind schedule, and unable to release promised earthmoving plant. Some
graders were used by day by KCG and by night by the task force. A call to Blomfield resulted in a grader being shipped from Adelaide to Watson two days later. The arrival of a 23-man detachment of the Radiation Detection Unit of the
Corps of Royal Canadian Engineers was expedited so they arrived in June, and were able to pitch in with the construction effort. In July, supplies coming from the UK were delayed by industrial action at the port of Adelaide. The work involved laying, testing and burying some of control cable. Each spool of cable weighed about , so where possible they were pre-positioned. The trenches were dug by a cable plough towed by a
Caterpillar D8 tractor. In some cases the limestone was too hard for the plough and the cable was buried by using a grader to cover the cable to the required depth. A similar procedure was followed for laying of power cable. Some 1,300 scaffold frames were erected for mounting instrumentation, held in place by 33,000 anchor pipes. Bunkers ranging in size up to were excavated with explosives and a compressor mounted on a four-wheel drive 3-ton Bedford truck connected to the
jackhammer part of the 4-inch wagon drill. Explosives were in the form of tubes of
plastic explosive left over from a
Bureau of Mineral Resources seismic survey of the area. The bunker work proceeded so well that the task force was able to assist KCG with its pit excavation work. Some instrument bunkers contained steel cubes. Getting them into the holes was tricky because they weighed , and the largest available crane was a Coles crane. They were manoeuvred into place with the assistance of a TD 24 bulldozer. The Coles crane was also used to erect the two shot towers. Concrete was made
in situ, using local quarry dust, limestone and bore water. The Canadians erected metal sheds of a commercial design, which were used to assess blast damage. A tented camp was built for observers at the post by the 23rd Construction Squadron. Pressed for time, Magee became involved in a series of disputes with the Woomera Range commander, who tried to divert his sappers onto other tasks. In June, the range commander ordered the surveyors to return to Adelaide, which would have brought the work at Maralinga to a halt. Magee went over his head and appealed to the commander of
Central Command,
Major General Arthur Wilson, who flew up from Adelaide and sacked the range commander. Impressed by what he saw at Maralinga, Wilson arranged for the task force to receive a special Maralinga allowance of 16
Australian shillings per day (), and additional leave of two days per month. The British Government added a generous meal allowance of
GBP £1 () per day, resulting in a diet of steak, ham, turkey, oysters and crayfish. In June, Beale flew in two planeloads of journalists, including
Chapman Pincher and
Hugh Buggy for a press conference. The task force completed all its work on 29 July, two days ahead of schedule, although KCG still had a few remaining tasks. By 1959, the Maralinga village would have accommodation for 750 people, with catering facilities that could cope with up to 1,600. There were laboratories and workshops, shops, a hospital, church, power station, post office, bank, library, cinema and swimming pool. There were also playing areas for tennis, Australian football, cricket and golf. ==Atomic Weapons Tests Safety Committee==
