“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.”
Where does the name of this documentary come from?
Australians and 
New Zealanders have long celebrated a public holiday known as 
“Anzac Day.” Held on the 25th of April (an anniversary associated with their 
Gallipoli landings), it honors the contributions of their armed forces. 
“ANZAC” is an acronym standing for the “
Australian and 
New 
Zealand 
Army 
Corps.” This corps was only active from 1914-1916 (an early portion of 
World War One), and then again in 1941 (a single year in 
World War Two). Nonetheless, the term 
“ANZAC” is now used to refer to virtually anyone who has served in the armed forces of either country, 
regardless of the literal meaning of what the acronym actually stands for. This may explain why the title of this documentary does not literally fit the acronym’s meaning. There are a number of ways in which this documentary departs from the literal meaning of 
“ANZAC,” since this covers Australian involvement in the 
entirety of 
World War II. That is to say, it goes from 1939 to 1945. There is brief mention of the contributions of 
New Zealanders (the other 
“ANZAC” nationality), but this documentary definitely focuses on 
Australia. It also covers their Navy and Air Force, and not just the “Army Corps” to which this acronym refers.
