Netherlands East Indies Forces Intelligence Service

Netherlands East Indies Forces Intelligence Service (also known by the acronym NEFIS), was a Dutch World War II era intelligence and special operations unit operating mainly in the Japanese-occupied Netherlands East Indies (now Indonesia).

Soon after the evacuation from the Dutch East Indies, a Dutch intelligence service was set up in Australia on the instructions of the Dutch Commander of the forces in the East, Helfrich.

It was called the Netherlands Forces Intelligence Service (NEFIS), and was based in Melbourne. The service initially consisted of two divisions: NEFIS I, responsible for military reporting, and NEFIS II, responsible for security.

NEFIS I gathered reports, maps, publications and photos on the Dutch East Indies. On the basis of this information, monthly summaries were issued on the situation in the archipelago.

NEFIS II was responsible for censoring the mail of Royal Netherlands Navy and KNIL personnel. It also checked whether the spouses of Dutch troops in Australia presented a security risk. It was not involved in carrying out secret intelligence operations. That was the task of the Inter-Allied Services Department (ISD), which was set up in April 1942 on the instructions of US General Douglas MacArthur, and was responsible for sending out agents to commit sabotage and gather intelligence in occupied areas. Two Dutch officers were assigned to the Dutch East Indies section, which, like NEFIS, was based in Melbourne.

A few months later, on 6 July 1942, the Inter-Allied Services Department was merged with other intelligence services operating from Australia. The new service was called the Allied Intelligence Bureau (AIB). It included a division responsible for gathering information on the enemy and carrying out sabotage operations. The Dutch section of the former ISD was incorporated into this division. The Dutch section carried out various operations in enemy territory. NEFIS was not given the task of sending agents on assignments until after the AIB had been reorganised in April 1943.
