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 Leslie Martin, the scientific adviser at the Department of Defence, could see no issues with the proposed tests, but recommended that in view of the prospect of tests being conducted
