Wongar settled on his bush property Dingo Den in Gippsland, south of Melbourne where, helped by photographic images from his "Totem and Ore" collection, he wrote his "Nuclear Trilogy", comprising the novels, "Walg", "Karan", and "Gabo Djara". The trilogy was first published in Germany, translated from the original manuscript by Annemarie and Heinrich Böll. The English language edition first appeared in 1988. It was launched at the Aboriginal Research Centre, Monash University, where Wongar at the time was serving as writer-in-residence. While he was at work, police raided Wongar's home at Dingo Den and took some of his work, including the sole copy of the manuscript of his new novel "Raki". In 1990, the Australian author Thomas Shapcott spoke about the case at the opening of the Adelaide Arts Festival. He circulated a petition asking the state authorities to see that the confiscated manuscript "Raki" be returned to Wongar. About 200 writers at the festival signed the petition. It took Wongar about 5 years to write "Raki" again. This was followed by his new book "Didjeridu Charmer", which will complete his nuclear series, thus making the series a quintet.
