How We Beat the Emden is a 1915 Australian silent film directed by Alfred Rolfe about the Battle of Cocos during World War I.

[4][5] Jack enlists in the Royal Australian Navy (RAN) and after training on the Tingira, joins the crew of HMAS Sydney.

[6][7] The film incorporates footage from the documentary How We Fought the Emden.

Actor C. Post Mason took a print with him to Canada in 1916 and screened the film over there.

[10] The Motion Picture News said the film was put on "principally with the idea of drawing patrons from" For Australia and was "merely a succession of interest and topical subjects woven together, and a plot that does not reflect much credit on either the author or producers".
