Explore the relationships within the terrorist cell that carried out the 2002 Bali bombings, killing 202 people, including 88 Australians.

The social network visualisation is based on research conducted by Stuart Koschade at the Queensland University of Technology, and published in his thesis, The internal dynamics of terrorist cells.

There were 17 individuals involved in the Jemaah Islamiyah operation between October 6 and the day of the bombings on October 12, 2002.

Imam Samudra emerges from the social network analysis as the most important figure in the JI cell, Koschade says. He was the most active member, had the most access to others, and importantly the greatest control over the flow of information.

Koschade's wider research into the social networks of terrorist cells suggests networks with a focus on efficiency rather than secrecy are more successful in completing their objectives.

He writes that the Bali cell found a compromise between structural efficiency and covertness.

Details about each individual's role in the attacks come from Koschade's research, as well as from ABC News reporting and the book Radical Pathways by Kumar Ramakrishna.
