The script held in the Crawford Collection in the AFI Research Collection contains the following character notes (excluding regular characters):
'TERRY HOOD Age 39. A farm labourer who lives with his wife and two kids in a rented house in a corner of his boss's land. A quiet, mellowed, even-tempered man - perhaps a little too easy-going for his own good. He lets his wife wear the trousers in the house - look after the money, supervise the kids - but that doesn't mean she dominates him. It's just agreed that he lets her take all the responsibilities. He's not going to change now. Rides horse.
'ROSEMARY (ROSIE) HOOD A bright 13 year old tomboy of a girl with much of her father's open good-nature combined with a deal more energy. The two most important people in her life are her dad and her elder brother, Frank, but before the end of the episode she will have seen both of them in a new light and understand their weaknesses for the first time. Rides horse.
'SALLY (SAL') HOOD Terry's wife. Middle 30's. Hard working and ready to take on all those responsibilities that her husband leaves to her. Realised a while ago that Terry was never going to be any difrerent [sic] so has tried to make her kids aware of the work outside of Terry's all-encompassing "She'll be right". Her advice has tended to fall on stoney ground and become indistinguishable from her general low-key, tidy-yourself-up nagging. And it is only nagging - she's not the real heavy she'd sound like if you took every word of hers literally.
'FRANK HOOD Age 18. A nice kid but of an age where he's quickly tiring of the seemingly aimless "Life on the farm". Doesn't know what he wants to do with his life but is certain that he doesn't want to end up the same as his father. He gets involved with Martin McGill to have some fun but then he gets out of his depth. It's a shame. Must ride and drive.
'TED BLAKE Middle-aged country garage proprietor. Easy going.'
