Z Experimental Station
The Z Experimental Station (ZES) was established in July 1942 at Munro Terrace, Mooroobool, Cairns, Queensland, Australia, jointly by Secret Intelligence Australia and the Inter-Allied Services Department. The building chosen to be the headquarters was known as "Fairview" (or House on the Hill), and it had been the home of Richard Ash Kingsford, the first mayor of Cairns and grandfather of aviator Sir Charles Kingsford Smith.
