William George Murray came home from WWI, during that time
In a letter to his parents, Murray described his participation in the battles at Gallipoli during August 1915.
Murray wrote about how the advancing Turks were mowed down with machine gun and artillery fire and how it was "great fun and very exciting."
He took up work in the Northern Territory of Australia in stock policing role:
In April 1919, Murray joined the Northern Territory Police as a constable and was posted to the very remote Ranken River police station on the Barkly Tableland.
Now, mixed race station workers, some white, some aboriginal, camped togther and in a dispute over a woman, an aboriginal man killed a white man over a rape. The rape violated both white and native law, as did the killing in revenge.
There was a single known perpetrator and ways and means to bring them to justice under either of two bodies of law with the cooperation of both groups of people.

Officially, 31 men, women and children were killed during this police operation, although analysis of the existing documentation and surviving Aboriginal testimonies indicate that somewhere between 100 and 200 people were shot dead.
