2. Australia
One of the reasons Australia is on our list of countries with the strictest customs, border control and airport security in the world is its geographic position and very specific flora and fauna. Since it is an island, the introduction of some unknown biological material could destroy its ecosystem and it wouldn’t be the first time foreign pathogens caused problems with wildlife, as we already mentioned earlier. These strict customs rules make Australian airports rank very high on our list.
