Factual error: Near the end of the movie, in the scene on the cliff, Charlie, Jessie and Louis are saved from impending murder when Senior Sergeant Jimmy appears, flying up in a helicopter and announcing he is from Australian Police. There is no police department in Australia called "Australian Police" - police departments in Australia are named after the state they are based in. As they are apparently near Alice Springs, Jimmy should have yelled out that he was from "Northern Territory Police."
Factual error: In the scene where Sal is sending Charlie and Louis to Australia, Frankie tells them to take the Old South Road due north from Sydney to Coober Pedy. When they are driving through the outback, they pass a sign which says "Alice Springs 15" and "Coober Pedy 550". This is can only be possible if they are driving south towards Coober Pedy from the northern part of Australia, not from Sydney.
