World War II began during the term of Robert Menzies. On 3 September 1939 Prime Minister Menzies announced:
"Fellow Australians, it is my melancholy duty to inform you officially, that in consequence of a persistence by Germany in her invasion of Poland, Great Britain has declared war upon her and that, as a result, Australia is also at war. No harder task can fall to the lot of a democratic leader than to make such an announcement." Menzies's later term saw the introduction of decimal currency, on 14 February 1966. Menzies, a devout monarchist, wished to name the currency "the Royal", and other names such as "the Austral" were also proposed. Menzies's influence meant that the name "Royal" prevailed, and trial designs were prepared and printed by the printing works of the Reserve Bank of Australia. The name "Royal" proved unpopular, and it was later shelved in favour of "Dollar".
