Summary

Musa Cerantonio and five co-offenders were sentenced for plotting to sail approximately 3,500 kilometers from northern Australia to Mindanao in the southern Philippines to engage in foreign incursion and hostile activities with Islamic State-affiliated militant groups. Cerantonio, a senior ISIS propagandist who had previously lived in Mindanao from 2013-2014, was the ideological leader of the group.

The plot became known as the "Tinny Terrorists" case after the group purchased a small boat for their attempted journey. Arrested in May 2016 before departing Australian waters.

Cerantonio's prior residence in Mindanao and his documented connections to Filipino ISIS recruiters, particularly Karen Aizha Hamidon (arrested October 2017), demonstrated established networks in the region. The case established the Philippines, specifically Mindanao, as a destination for Australian extremists seeking to join Islamic State operations. This was one year before the 2017 Marawi siege.

Key Facts

Robert Cerantonio, born in Melbourne, was a convert to Islam who became a prominent ISIS propagandist. He lived in Mindanao, Philippines from 2013 to 2014, where he established connections with local Islamic State supporters and recruiters. During this period, he was described as a "close associate" of Karen Aizha Hamidon, a Filipino woman who would later be arrested in October 2017 for ISIS recruitment activities.

Cerantonio was arrested in Cebu, Philippines in July 2014 and deported to Australia.

After his return to Australia, Cerantonio's passport was cancelled. No legal travel overseas. In early 2016, he began planning an alternative route to return to the Philippines by boat. Federal Court documents in subsequent control order proceedings described the plot as "the Respondent's attempt (by agreement with his co-offenders) to travel to the Southern Philippines (where a number of Islamist militant groups operated) with the intention of his co-offender, Mr Cerantonio, engaging in hostile activity."

The Southern Philippines region, particularly Mindanao, was home to multiple Islamic State-affiliated groups. Abu Sayyaf. The Maute Group. Dawlah Islamiyah.

In May 2016, Cerantonio and five associates—Paul Dacre, Kadir Kaya, Antonio Granata, Shayden Thorne, and Murat Kaya—purchased a small boat and prepared to sail from Australia's northern coast to Mindanao. A distance of approximately 3,500 kilometers. Arrested before departing Australian waters.

The Australian Federal Police's intervention prevented what would have been an extraordinarily dangerous sea voyage by individuals with limited maritime experience.

Federal Court documents in later control order proceedings established that Paul Dacre, one of the co-offenders, was "susceptible to the influence of Mr Cerantonio." Cerantonio's role as ideological leader of the cell confirmed. Control orders subsequently imposed on both Dacre and Adam Brookman (a Syria foreign fighter with no direct involvement in the boat plot) prohibited contact with Cerantonio and specifically mentioned persons in "Philippines or Indonesia." Ongoing concerns about his network connections in Southeast Asia.

The plot occurred one year before the Marawi siege in May 2017. ISIS-affiliated Maute Group militants occupied Marawi City in Mindanao for five months. Over 1,000 deaths. Cerantonio and his network were attempting to reach Mindanao before the most prominent ISIS operation in Southeast Asia.

The 2019 sentencing of Hanifi Halis, Samed Eriklioglu, and Ertunc Eriklioglu in the Victorian County Court documented that Melbourne extremists discussed "Musa tried to go" when considering their own options for leaving Australia. Cerantonio's Philippines boat plot was known to and discussed by other extremist networks in Australia.

Sentence

Musa Cerantonio was sentenced to 7 years imprisonment for his role as leader and organizer of the foreign incursion plot. The other co-offenders received varying sentences reflecting their different levels of involvement.

Cerantonio's sentence reflected his position as ideological leader, his prior residence and established networks in Mindanao, his role in ISIS propaganda, and his initiating and organizing the boat plot. The Court took into account that the plot was disrupted before the group could depart Australian waters. But also considered the serious nature of the intended destination—a region with active ISIS-affiliated militant groups—and Cerantonio's prior experience and contacts in that region.

Following release from prison, Paul Dacre and other co-offenders became subject to control orders prohibiting contact with Cerantonio and other network members, and prohibiting travel to or contact with persons in the Philippines or Indonesia. These ongoing restrictions, confirmed by the Federal Court in 2021 (Booth v Dacre [2021] FCA 796), demonstrate continued concern about Cerantonio's influence and the potential for his network connections to facilitate future foreign incursion attempts.
