Adelaide — Maralinga Cover-Up Secrets

🎭Your Mission

You are William Light, Adelaide's surveyor-general in 1837, whose plan shaped the city.

Your mission: decipher clues left by a secret society seeking to expose the truth

Uncover the untold secrets of Adelaide, where the shadow of the Maralinga nuclear tests still looms over Victorian buildings and historic squares.

« In memory of the Aboriginal people who died during the colonisation of South Australia 1800s »
Inscription on the South Australian Native War Memorial, 1988

The story that haunts this land

Your quest begins at Adelaide's Parliament House, a Victorian Italianate building constructed between 1874 and 1889, designed by Edward John Woods. Officially opened on April 5, 1889, by Governor Sir William Robinson, it has since housed the Parliament of South Australia. On its 100-meter long facade, you decipher the first signs of a conspiracy, discrete symbols guiding you to the past. This building, designated a national historic site in 1975, is the starting point of your exploration of the North Terrace Cultural Boulevard, an essential route for understanding the history of South Australia.

Next, Victoria Square / Tarntanyangga, the central 4.6-hectare square planned in 1837 by Colonel William Light, reveals its role in protest movements. A traditional Kaurna site, named Tarntanyangga, 'place of the red gum trees', this square was the scene of the Aboriginal Rights March in 1966. The central fountain installed in 1968 and the 'Ngargee' Aboriginal sculpture from 1993 recall the complexity of Australian history. Here, clues mingle with the stories of Robert Lawson, colonial engineer, and demands for justice, immersing you in Adelaide's past tensions.

Your journey takes you to the University of Adelaide, founded on March 6, 1874. The first Australian university to admit women upon its opening, it symbolizes an era of progress. The main campus, opened in 1876, with the Mitchell Building completed in 1882, has seen 8 Nobel laureates, including Howard Florey for penicillin in 1945. The buildings, listed on the State Heritage Register in 1978, conceal archives you must consult to advance your investigation into the secrets of Maralinga, which may well have links to local scientific research.

The Tandanya National Aboriginal Cultural Institute, opened on October 20, 1989, at 253 Grenfell Street, is your next stop. Australia's first national urban Aboriginal cultural center, it is named Tandanya ('gathering place' in Kaurna language). This renovated Victorian building from 1894 exhibits over 3,000 Aboriginal artifacts and has hosted temporary exhibitions since 1989. It is here that you meet an informant who enlightens you on the links between nuclear tests and Aboriginal communities, a crucial perspective for understanding the impact on populations and the heritage of South Australia.

Finally, the South Australian Native War Memorial in Pennington Gardens, North Terrace, erected in 1988 and inaugurated on December 10, 1988, by Premier John Bannon, is the first memorial in Australia recognizing the 'Aboriginal Wars' (1836-1852). Its inscription, 'In memory of the Aboriginal people who died during the colonisation of South Australia 1800s', resonates with your quest for truth. This place of remembrance offers a final perspective on the sacrifices and silences that have marked the region's history. You leave Adelaide with a deeper understanding of the issues, historical figures like John Langdon Parsons, and events that shaped South Australia, well beyond the appearances of the North Terrace Cultural Boulevard.
