in 1886, although the large 6 ha section was subdivided from 1905 and the house was converted into flats in the late 1920s. The house still retained rooms with marble fireplaces, ornate plaster and 4.8m high ceilings, and the building remained the main administrative and training centre for the bureau. When the bureau assumed an augmented role to coordinate land and air forces signals intelligence, additional facilities were located a few minutes walk away at a small public park opposite the Ascot railway station Hence it became known as "Ascot Park" although officially called "Oriel Park". Between the station, Kitchener Road and Lancaster Road, the park had nearly 20 temporary army wooden huts by mid-1943 and 31 by September 1945. Across the road at 77 Kitchener Road a disused brick Fire Station was used for banks of IBM punched card equipment used by cryptanalysts to analyze intercepted cyphertext. The machines had been in the garage at the rear of 21 Henry Street but the noise from all-hours operation bought complaints from neighbours. When the IBM machines were removed from 21 Henry Street the garage was occupied by No. 11 Australian Cypher Section and filled with Typex machines which were operated mostly by Australian Women's Army Service (AWAS) personnel. Beginning in January 1942, U.S. Navy stations in Hawaii (Station HYPO), Cavite/Corregidor (Station CAST) and OP-20-G (Station NEGAT, at Washington) began issuing formal intelligence decrypts far in advance of the U.S. Army or Central Bureau. FRUMEL in Australia obtained IBM equipment in 1942 to replace that which had been left behind in Manila Bay on leaving Corregidor and employed it throughout their tenure in Melbourne. Japanese POW's were interrogated by the ATIS at a house called "Tighnabruaich" at Indooroopilly in Brisbane. Central Bureau at 21 Henry Street, Ascot, in Brisbane decrypted a Japanese Army Air/Ground signal intercepted by 51 Wireless Section in Darwin that contained Admiral Isoroku Yamamoto's itinerary for an upcoming trip to Rabaul. Admiral Yamamoto, was the Commander in Chief of the Combined Japanese Fleet, the architect of the attack on Pearl Harbor. Central Bureau reportedly sent the decrypted message to FRUMEL where it was reportedly translated by a U.S. Navy linguist. Although Central Bureau may have decrypted the message, the interception of his flight was based on decrypts of Japanese naval messages by FRUPAC/Station HYPO in Hawaii, FRUMEL, OP-20-G in Washington and Station AL on Guadalcanal.
