Even in the middle of nowhere on the Nullarbor Plain, the border entry into Western Australia is a checkpoint. Here it is not the passports or stowaways that are checked but the presence of ... fruits and vegetables (and a whole list of prohibited items available here) which must be disposed of at the border. Officially, it is a measure to protect the agricultural industry of the state by preventing the transportation of some insects, weeds and diseases present elsewhere in Australia. It is understandable not to import fruits and vegetables just in case they are contaminated. Yes, but a question remains. What about the insects? Don't they ever cross the border on their own? We had already experienced this kind of quarantine arriving in Tasmania. In this case though it made more sense as it is an island.
