Arguable Australia's first war film, set during the Second Boer War (although including events from the First Boer War).
According the contemporary reviews:
The star film, entitled 'Mates of the Murrumbidgee,' depicts the life of two boys and a girl. The sequel to a capital love affair is that the girl poisons herself, and one of the boys shoots his old-time mate for having robbed him of his promised wife.
