A man previously linked to Islamic State sympathies and subjected to a high-risk terrorism supervision order has been found in breach of his conditions after meeting with a convicted terrorist associate in Sydney. Greg Ceissman, 32, who was once accused of plotting an attack on a shopping center, was discovered having lunch with Alo Bridget Namoa, known as one half of a couple labeled the “Jihadi Bonnie and Clyde,” according to court documents.

Ceissman was placed under an extended supervision order (ESO) by the New South Wales Supreme Court just days before his scheduled release from custody in July 2018. The ESO allows for continuous monitoring due to concerns over his radicalization and a history of expressing hostility toward police. Authorities allege he made threats to a fellow inmate, including plans to attack Marrickville Police Station, behead officers, and detonate explosives at Bankstown Shopping Centre. While these claims prompted the court intervention, Ceissman has never been formally charged with terrorism offenses.

Since being placed under the order, Ceissman has repeatedly violated its conditions. The most recent breach occurred in June 2025 when he was seen publicly with Namoa at Broadway in Sydney. Phone records reviewed by authorities revealed multiple communications between the two, including dozens of text messages and calls. Namoa, along with her husband Sameh Bayda, was convicted for plotting a terrorist attack on New Year’s Eve in 2015 when both were 18 years old. She served a prison sentence of two years and 10 months.

In April, Ceissman pleaded guilty to 12 counts of breaching his ESO. Prosecutors successfully argued last week that he should be remanded in custody pending sentencing, stating that it was “inevitable” he would receive a full-time jail term due to the extent of his violations.

Ceissman’s case highlights ongoing challenges authorities face in monitoring and managing individuals assessed as high-risk terrorism threats within the community. The extended supervision order regime is designed to mitigate such risks through strict oversight, yet enforcement difficulties remain evident in Ceissman’s repeated breaches. Sentencing is expected to take place in the near future.
