Len Beadell was leading a survey party through the mulga scrub of central South Australia, when he came across something unusual, even unnerving. ‘It was almost like a picket fence’, he described, with posts made from ‘slivers of shale’. Being in such an isolated location, he decided ‘it was obviously an ancient Aboriginal ceremonial ground built by those primitive, stone-age nomads in some distant dreamtime’ – an Aboriginal ‘Stonehenge’. As he scrabbled in the dust, searching for a piece of charcoal that might be used to fix this eerie structure in time, Beadell pondered the ‘ironic clash of old and new’: ‘only a few short miles away the first mighty atomic bomb ever to be brought to the mainland of Australia was to be blasted into immediate oblivion … and it was by-products of this very weapon which could be used for determining the age of the charcoal from these prehistoric fires’.^[48] Beadell’s expedition had set out from the British atomic test site at Emu Field, searching for a permanent testing range – one that would become known as ‘Maralinga’.^[49] It was 1953, and something new was coming.

The ‘clash of old and new’, the sense of disjunction, was a familiar characteristic of frontier experience. But with the coming of the atomic bomb, the sense of ‘newness’ seemed to have become more acute. The destruction of Hiroshima was revealed unto a shocked world as the harbinger of a new age – the ‘atomic age’. Media reports talked about ‘new vistas’, a ‘new era’ in world affairs, a ‘revolution’ in daily life.^[50] The atomic bomb, Clem Christesen wrote in Meanjin, had ‘severed the old world from the new with guillotine-like decisiveness’.^[51] Most importantly, the world faced new challenges, for the atomic age carried grave implications for the future of humanity. It was a ‘turning point’, ‘perhaps the most solemn turning point of all history’, Rev. Dr C. N. Button warned his Ballarat congregation: ‘Humanity is at the crossroads’.^[52]

The Sydney Morning Herald relayed the news from Hiroshima under a pair of significant subheadings: ‘Terrifying New Weapon’ and ‘Big Possibilities In Peace’.^[53] The ‘good’ atom/‘bad’ atom routine dominated much public understanding of this mysterious technology.^[54] It was a formula popularly represented in the image of the atomic crossroads, placing humanity at a fork in the road of destiny, with a signpost pointing one way to destruction and the other to progress. Which was it to be, apocalypse or utopia? There was no escaping; it was time to choose. The assumed imminence of the crossroads, the disjunctive dynamic of the atomic age, obscured much of its familiarity. Like the frontier, the crossroads gained its metaphorical power from the conjunction of opposites. The wonders of a techno-utopia shone invitingly amidst the menacing gloom of atomic obliteration. But there was no choice. The signpost to destruction was a warning, a lesson to be learnt. Just as it had in Groom’s plans for northern development, progress in the atomic age used the threat of dissolution to charge itself with the force of destiny. Both imagined a future fulfilled through the accumulation of space, whether by the inexorable expansion of Australia’s frontiers, or by a continuing march along the road to atomic nirvana. Both offered a journey from which there was no turning back.

In the glare of an atomic explosion, Len Beadell imagined, the mulga scrub around him would instantly ‘come to life’.^[55] At the dawn of this ‘new’ age, the image of vast expanses of idle and wasted land, silently awaiting the transforming power of science, continued to evoke enthusiasm. As Britain’s readied its big bang at Emu Field, the Sunday Herald keenly anticipated the moment when the ‘inland silence that remained unbroken for ages’ would be ‘shattered’ by the bomb. Australia’s desert lands had found a new destiny, for ‘the very poverty of these areas in surface resources made them valuable in the atomic field, either as a storehouse of uranium riches or as the kind of waste land where experiments can be most safely conducted’.^[56] Ivan Southall described the Woomera rocket range, established some years earlier, as an ‘open-air laboratory’: ‘one of the greatest stretches of uninhabited wasteland on earth, created by God specifically for rockets’.^[57]

Even as rockets were being propelled into ‘space’ (the final frontier), science presented the land with yet another chance for renewal. Woomera and the atomic tests brought science and land together with a familiar mix of imperial loyalties and national self-interest, development and defence. The Minister for Supply, Howard Beale, sought to justify the establishment of the Maralinga range by portraying it as ‘a challenge to Australian men to show that the pioneering spirit of their forefathers who developed our country is still the driving force of achievement’.^[58] These new pioneers had the opportunity to contribute to the deterrent power of the free world, while possibly winning Australia access to the secrets of the atomic age. Distorted echoes of Deakin’s ‘citizen soldiery’ rang down the years, charged with imminence of the crossroads challenge.
