A large two story house located at 21 Henry Street, Ascot in Brisbane was probably acquired by Hirings Section, No. 1 Lines of Communication (No. 1 L of C), Australian Army

The house at 21 Henry Street was used by:-

- Central Bureau   (Gen. MacArthur's own signals intelligence unit)

- No. 1 Wireless Unit trained by AIB

- No. 11 Australian Cypher Section, Royal Australian Corps of Signals

- 837th Signals Service Detachment 

Central Bureau had banks of IBM Tabulators, the forerunner of computers, which were used by the cryptanalysts to sort and strip away ciphers which concealed the original text. They were located in the garage at the rear of 21 Henry Street. The IBM machines were later moved from the garage to the Fire Station at Ascot Park. The garage was then occupied by No. 11 Australian Cypher Section. The garage was filled with Typex machines which were operated by some Australian Women's Army Service (AWAS) personnel. 


Central Bureau re-union at 21 Henry Street on 1 May 1988 
Organised by Central Bureau Intelligence Corps Association
