The novel's author, Kenneth Cook, based the fictional town of Bundanyabba on Broken Hill in New South Wales, where much of the movie was filmed on location. The train is seen arriving at "Bundanyabba Sulphide St" station, and Sulphide Street is a genuine station in Broken Hill. Broken Hill is one of the most isolated inland towns in Australia.

The sudden eerie silence and dimming of the lights in the bar portrays a ritual that still occurs most evenings in Returned & Services League (RSL) clubs across Australia. Each evening the lights are briefly dimmed and patrons are expected to stand in quiet remembrance of fallen service personnel. Usually the ceremony will coincide with the recitation of the 'Ode of Remembrance', a stanza of Laurence Binyon's 'For the Fallen', through the club PA. It reads: "They shall not grow old, as we that are left grow old. Age shall not weary them, nor the years condemn. At the going down of the sun and in the morning, We will remember them." This is followed by one or two minute's silence, and then the spoken promise by all: "Lest We Forget".
