The 2005 Nias Island Sea King crash was the crash of a Royal Australian Navy (RAN) Westland WS-61 Sea King helicopter (tail number N16-100, call sign "Shark 02") of 817 Squadron RAN at approximately 4 pm (local time) on 2 April 2005 with 11 personnel on board. The accident occurred while "Shark 02" was making its approach to land on a sports field located near the village of Tuindrao in the region of Amandraya on the Indonesian island of Nias. "Shark 02" had been providing humanitarian support to the people of the earthquake-devastated region. A Defence Board of Inquiry later found that the primary cause of the accident was a failure of the aircraft's flight control systems. This was as a result of a series of errors, and a general practice of poor maintenance on the aircraft. Casualties Nine personnel died in the accident, including six members of the RAN and three members of the Royal Australian Air Force. Two personnel survived the crash: Navy Leading Seaman Shane Warburton, and Air Force Corporal Scott Nichols.

The service was attended by family members, friends and colleagues of all nine members killed, and by both survivors.
