The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'NARELLE A fluffy blonde in her early 20's, somewhat childish and none too bright. She works as a prostitute and there is more than a hint of a lesbian relationship with her "Friend", Patsy.'PATSY One or two years older than Narelle - tall and dark with a dominant personality. She favours clothes with a masculine flavour - although not too overtly so. For example, slack suits but never collars or ties. A fairly tough spirit, she is the driving force in her criminal ventures with Narelle.
'BRUCE CLARKE Mid 40's. Prize-winning door-to-door salesman of encyclopedias. Bespectacled, fast-talking would-be man-about-town. He picks up Narelle and Patsy, is robbed by them, and is in terror of what his wife will say.
'ERNIE JACOBS Late 40's - a big man, moody, with an explosive temper. A fellow-salesman with Bruce. He has lost his wife to another man, visits her while in Melbourne and unsuccessfully tries to argue her back.
'DENNIS MASON Age 23-28. The youngest of the three salesmen who have a night out. Good-humoured, eager to please, sensible.
'BRENDA JACOBS Late 30's. Ernie's run away wife. Attractive in a domestic sort of way, she is six months pregnant at the time this story takes place. She has left Ernie because he could not give her the child she wanted. A sympathetic character.
'TOM BAKER The man with whom Brenda is living. Late 30's or early 40's, must be smaller than Ernie, must be able to drive a truck. He is in league with some tough criminals, and helps them to organize robberies from trucks. His eyesight is failing because of optic nerve trouble. Occasionally, especially in moments of stress, he presses his fingers to his eyes, suffering a headache.
'MIKE BURNS / STEVE BURNS Two professional criminals - late 20's, or early 30's. Steve must be driver [sic], both should look good in a fight.
'EDDY GRIGG Mid-50's - respectable-looking, bespectacled, business-suited customer who is robbed by Narelle and Patsy. Appears in Teaser only. Car-driver. Losing his hair.
'BILL FRANKLIN Mid 30's, Tom Baker's mate on the truck. Two scenes only. A little dialogue.
'TRUCKY Any age, able to drive a truck, two scenes in which he befriends Narelle and Patsy when they are hitching a lift. Good, friendly type.

'ROSIE BURNS Mid-20's, the wife of Mike Burns - she runs the roadhouse which they own. A criminal's wife - tough but with a certain homely quality. Not brassy or flashy.
'BARLADY: A motherly figure to whom the three salesmen tell their troubles.
'MACGREGOR A drunk, around 50, with a Scottish accent. Fairly rough, a regular customer at the police station. Likeable withall.
'"BENNO" BENEK MacGregor's companion. New Australian drunk, with little English or dialogue. The straight man in MacGregor's knock-about turn. Likeable and comic.
'WAITRESS Works in Kaufmann's club, young, sexily built, sexless personality. One scene only.
'HOTEL WAITER About 40, serves Bruce Clarke with champagne in his room. Calls the police when Bruce is robbed and is contemptuous of Bruce's association with Narelle and Patsy.
