Before his arrest, Cerantonio had long corresponded with ISIS fighters through social media.John Safran, “Musa Cerantonio: Muslim convert and radical supporter of Islamic State,” Sydney Morning Herald, January 17, 2015, http://www.smh.com.au/good-weekend/musa-cerantonio-muslim-convert-and-radical-supporter-of-islamic-state-20150116-121c8s.html.

In 2013, Cerantonio hosted the English-language show “Ask the Sheikh,” in which he answered questions on sharia (Islamic law) from viewers around the world.

Born Robert Cerantonio to an Irish-Catholic family, Cerantonio converted to Islam when he was 17 years old.Melissa Hills, “‘You CAN go to paradise even if you are killed by a woman’: Aussie hate preacher dismisses ISIS fears of ‘virgin-less heaven’ if they are killed by Kurdish female fighters,” Daily Mail, November 7, 2014, http://www.dailymail.co.uk/news/article-2825314/Australian-hate-preacher-posts-new-extremist-messages-online-telling-fighters-Paradise-die-Islamic-faith.html. Cerantonio is an aficionado of Islamic history. In particular, he enjoys retelling the story of “when the Muslims fought Dracula,” the death of Ottoman leader Muhammad al-Fateh at the hands of Vlad the Impaler. He married a Filipino woman, Joan Montayre, who remained in the Philippines after he was deported in July 2014. He also has two daughters from a previous marriage to a Lebanese woman in Australia.John Safran, “Musa Cerantonio: Muslim convert and radical supporter of Islamic State,” Sydney Morning Herald, January 17, 2015, http://www.smh.com.au/good-weekend/musa-cerantonio-muslim-convert-and-radical-supporter-of-islamic-state-20150116-121c8s.html.
Cerantonio has been largely quiet on social media since he returned to Australia. In January 2016, media reports revealed that he was maintaining an Instagram account under an alias after he posted a picture of himself at the Vatican holding a black flag with the Arabic for “There is no God but Allah and Mohammad is the messenger of Allah.” The picture was reportedly up to four years old. Cerantonio largely posted pictures of himself on the account, according to reports. As of April 2016, he reportedly had 127 followers on Instagram and followed 178 accounts, mostly belonging to ISIS supporters.Candace Sutton, “Australian jihadi extremist returns to social media preaching with photo holding Islamic flag outside the Vatican to promote view that 'Christians don't deserve churches,’” Daily Mail, January 6, 2016, http://www.dailymail.co.uk/news/article-3387835/Australian-jihadi-extremist-returns-social-media-preaching-photo-holding-Islamic-flag-outside-Vatican-promote-view-Christians-don-t-deserve-churches.html;

Australian federal police arrested Cerantonio and four other Australian men on May 10, 2016, on the suspicion that they were planning to sail to Indonesia. The group had towed a seven-meter boat for at least 31 hours from Melbourne to Cape York in Queensland when police arrested them. The group reportedly bought the boat in Melbourne, and it appeared to be at least 30 years old. It was the first known attempt by would-be foreign fighters to leave the country by boat, according to Attorney General George Brandis.Michael Safi and Josh Robertson, “Musa Cerantonio among men arrested after allegedly trying to sail to Indonesia,” Guardian (London), May 11, 2016, http://www.theguardian.com/australia-news/2016/may/11/musa-cerantonio-among-men-arrested-after-allegedly-trying-to-sail-to-indonesia;

The Brothers Behind Bars Facebook page has called for donations to pay for the legal fees of Cerantonio and his four alleged co-conspirators.

In October 2021, Australian media reported Cerantonio had written a letter to a friend that past June renouncing “Islam and jihadist extremism.”David Hurley, “Tinnie terrorist renounces ‘evil’ wrongs in prison letter,” Herald Sun (Southbank), October 10, 2021, https://www.heraldsun.com.au/truecrimeaustralia/tinnie-terrorist-renounces-evil-wrongs/news-story/13a949f65b3870d5407e789cabb4afb7. Cerantonio wrote he felt “terrible” knowing he influenced others to “dedicate themselves to tyrannical death cults.”David Hurley, “Tinnie terrorist renounces ‘evil’ wrongs in prison letter,” Herald Sun (Southbank), October 10, 2021, https://www.heraldsun.com.au/truecrimeaustralia/tinnie-terrorist-renounces-evil-wrongs/news-story/13a949f65b3870d5407e789cabb4afb7. According to the letter, Cerantonio had spent a large amount of time reading and researching while in prison and undergone a “religious and ideological belief since mid-2019.”David Hurley, “Tinnie terrorist renounces ‘evil’ wrongs in prison letter,” Herald Sun (Southbank), October 10, 2021, https://www.heraldsun.com.au/truecrimeaustralia/tinnie-terrorist-renounces-evil-wrongs/news-story/13a949f65b3870d5407e789cabb4afb7. In the letter, Cerantonio referred to ISIS as “suicidal maniacs” and a “death cult.”David Hurley, “Tinnie terrorist renounces ‘evil’ wrongs in prison letter,” Herald Sun (Southbank), October 10, 2021, https://www.heraldsun.com.au/truecrimeaustralia/tinnie-terrorist-renounces-evil-wrongs/news-story/13a949f65b3870d5407e789cabb4afb7.

In a March 2022 piece for the Atlantic, journalist Graeme Wood revealed he had been the recipient of Cerantonio’s 2021 letter renouncing ISIS. According to Wood, Cerantonio also renounced Islam and became an atheist and reader of renowned atheist and author Richard Dawkins—though Cerantonio has said he still disagrees with Dawkins in several areas. In Wood’s account, Cerantonio reached his conclusion about Islam while studying the Quran in prison. He focused on a figure in the 18th chapter of the Quran called Dhu-l Qarnayn, “the two-horned one.” According to Wood, Cerantonio noted similarities between Dhu-l Qarnayn and a fabulized version of Alexander the Great in Aramaic, which he later determined the Quran had plagiarized. Cerantonio wrote to Wood, “Realizing that Dhu-l Qarnayn was not at all a real person but was rather based on a fictional account of Alexander the Great instantly left me with only one possible conclusion: The Quran was not divinely inspired.”Graeme Wood, “Why an ISIS Propagandist Abandoned Islam,” Atlantic, March 31, 2022, https://www.theatlantic.com/ideas/archive/2022/03/deprogramming-isis-supporters-jihadi-extremism/629433/. Cerantonio told Wood ISIS’s murderous activities were consistent with what he knew of Islamic teachings, but the Alexander plagiarism failed intellectual tests.Graeme Wood, “Why an ISIS Propagandist Abandoned Islam,” Atlantic, March 31, 2022, https://www.theatlantic.com/ideas/archive/2022/03/deprogramming-isis-supporters-jihadi-extremism/629433/. After abandoning Islam, Cerantonio began using his English name, Robert. While serving the remainder of his sentence, he has also met with other jihadists in prison to help deprogram them. Wood reported Cerantonio has had some success but his own deprogramming—based on in-depth readings using multiple translations—is not easily replicated because of the time, patience, and level of education necessary to reach the same conclusions as Cerantonio.Graeme Wood, “Why an ISIS Propagandist Abandoned Islam,” Atlantic, March 31, 2022, https://www.theatlantic.com/ideas/archive/2022/03/deprogramming-isis-supporters-jihadi-extremism/629433/.
