Continuity mistake: When Mitzi and Felicia wake up the morning after they left Bernadette and Bob to get drunk, if you look at the shot out of the bus window of Bob and Bernadette, Bernadette's face is next to the cake. Once Mitzi and Felicia are out of the bus, Bernadette's face is on top of the cake.
Continuity mistake: Tik is practising their dance routines and he is wearing a green dress and he's got a cigarette in his hand. In one shot the cigarette is there and in the next, which is far away, it's not there.
Visible crew/equipment: The morning after Priscilla breaks down in the outback, during breakfast an argument breaks out. During this the reflection of the cameraman and boom man can be seen in sunglasses.
