Continuity mistake: When Lady Ashley meets Kipling Flynn in his shed, he pulls out a new bottle of "Poor Fella Rum". When he pulls the cork out, it is a different bottle shape and almost completely empty, but then it goes back to a full bottle. (00:33:50)
Continuity mistake: During the cattle drive Nullah starts out by riding a Skewbald (brown and white) horse but in subsequent shots the horse is Piebald (black and white). In later scenes the horse remains Piebald but the pattern of the markings changes between shots indicating that the pony was actually grey.
Continuity mistake: As Mr. Fletcher is riding up on horseback to greet Lady Ashley, you can see him riding up next to a parked, red truck, that has the front end pointed away from the house. Keep an eye on that truck, because it will have the front end pointing towards the house, as Fletcher gets closer to Lady Ashley. (00:27:50)
Continuity mistake: At the beginning of the stampede, Drover places a black hat on Sarah's head. During the stampede, her hat is now light brown. (00:59:35)
Answer: So they'd be unable to water their cattle. Which has two benefits for Fletcher. The first being that they'd have to take their cattle to the watering hole on the border of their property, making it easier for Fletcher to steal the cows. Second, and more long term, their cattle would be of poorer quality due to lack of proper care. The ranch would lose money as a result, and they'd be more amenable to selling the ranch to their competition, whom Fletcher works for.
