The Australian law enforcement response to the Bali nightclub bombings in October 2002 is one of the most significant operations ever undertaken by Australian law enforcement agencies. Led by the Australian Federal Police, the operation was a multijurisdictional response by Australian commonwealth, state, and territory law enforcement agencies. Australian state and territory police services played a major role in ensuring the response from Australia was comprehensive and coordinated. At the height of the investigation, approximately 500 Australian police members were deployed on matters relating to the bombings, with approximately 400 of these in Australia.
