Corrected entry: Dundee explains that he has no idea how old he is as he does not know when he was born, and that his birth was never registered. This would make it impossible for him to obtain a passport, and he could not have travelled to the United States without one.
Corrected entry: When the guy in the bar calls Mick a "bloody croc poacher", Mick punches him in the face then turns round to Sue saying "Sorry about that, but I won't have anyone using bad language in front of a lady." However, Mick had just said "How would I know, shit for brains?" in front of Sue when the same guy asked where he could hunt crocodiles. Mick also says "You can live on it, but it tastes like shit" to Sue when she asks if he is going to have any goanna, yams, grubs or sugar ants. (00:09:40 - 00:38:15)
Corrected entry: In the scene when Mick Dundee arrives in New York, Sue is shown meeting her boyfriend and says she was separated from Mick in customs. Mick is shown to be leaving Australia on Qantas. Passengers entering the US always have to clear customs in their first port of entry, which for Qantas in 1986 was only Los Angeles.
Corrected entry: Mick Dundee is supposed to be an master bushman with a lifetime's experience as a hunter - yet he plays a joke on a woman by firing a .308 bullet into the shingle on the ground at her feet. The ricochet from a .308 bullet fired from a metre away could go anywhere, and could easily kill her - or him. Anyone with his experience with guns would know that.
Corrected entry: When the trio drives out to the location where Mick was attacked, they encounter a water buffalo in the middle of the track. Mick honks the horn and yells to get it to move, then gets out of the truck and hypnotizes the beast. Where does it fall over and go to sleep? Right there in the middle of the track. It strikes me that it would be much more difficult to move a sleeping buffalo than one already on its feet.
