After the bus breaks down for the first time in the Australian outback, and Tick (Hugo Weaving) has just given up on trying to fix it, he sits down to eat breakfast with Bernadette (Terence Stamp). In the exchange, a cameraman and some crew members are visible in the reflection of Bernadette's sunglasses.
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.
When they are in the bar in Broken Hill, Old Shirl comes over and slaps her right hand down on Bernadette's. Then, in the next camera shot, it's her left hand.
Tick is practicing 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.
