  • August 1915 Admiralty asks Naval Board to decypher a German message in the HVB code intercepted by the SS Orama. April 1916 ACNB requested that Commonwealth wireless stations monitor Dutch stations in the Netherlands East Indies and forward any messages intercepted to Navy Office for investigation. By the end of April this instruction was rescinded as no useful information was found in the messages that had been intercepted. June 1918 ACNB forwarded copies of wireless telegraph messages, to and from Japanese residents in the Pacific, to the Attorney-General’s Department. In the main these messages were either commercial in nature or requests for funds and payments. July 1918 The radio station at Broome also forwarded details of intercepted Dutch traffic to Navy Office.
