installed in No. 24 French Street. On 25 April 1942 this small RAAF Unit was given its new name of No. 1 Wireless Unit and then became part of General Douglas MacArthur's new joint American-Australian Sigint organisation called Central Bureau in Ascot, Brisbane. Under some American pressure on the RAAF No 1 WU accompanied the American forces, going to Port Moresby in 1943, and Lae Nadzab Airport, Owi & Biak in 1944 (they were the only Australians on Biak). The WU could give up to 3 hours warning of Japanese air raids. Bleakley then went with No 5 WU to the Philippines in 1945.
