World War I: The guns of Point Nepean fort at Port Phillip Heads in Victoria (Australia) fire across the bows of the Norddeutscher Lloyd steamer SS Pfalz which is attempting to leave the Port of Melbourne in ignorance of the declaration of war and she is detained; this is said to be the first Allied shot of the War.

Pfalz was a 6,557-ton cargo steamer operated by German shipping company Norddeutscher Lloyd. The ship became the target of the first shot fired by Australian forces in World War I, soon after departing the Port of Melbourne in Australia.
