For the Honour of Australia was made for British audiences, by compiling footage from two films (For Australia and How We Beat the Emden) and constructing a new over-arching narrative that presented the protagonists of the two entirely separate films as brothers, living out asynchronous war experiences that only briefly overlap.
Australian Screen Online (see link below) points out that the two films were made by rival companies (J.C. Williamson's and Australasian Films), and there is no current information on who spliced the two films into this new release.
