 From March 1938 Blamey supplemented his income by making weekly broadcasts on international affairs on Melbourne radio station 3UZ under the pseudonym "the Sentinel". Like the station's general manager, Alfred Kemsley, Blamey felt that Australians were poorly informed about international affairs, and set about raising awareness of matters that he believed would soon impact them greatly. He was appalled at Nazi Germany's persecution of Jews, and saw a clear and growing menace to world peace from Nazi Germany and the Empire of Japan. His 15-minute weekly talks continued until the end of September 1939, by which time the war that he had warned was coming had started.
