Anybody that’s shipped a vehicle into Australia before knows the pain of quarantine cleaning and many people seem to have heard the stories !
Customs aren’t a problem, that’s “just” paperwork, the quarantine service though is a pain. Essentially the vehicle has to be spotless for understandable reasons, it’s all about protecting the very ecology that we’re going to experience. Sometimes though it feels like you are fighting a losing battle. You can spend weeks cleaning every inch of the vehicle over and over and you can almost guarantee that quarantine will still insist on another clean and in some cases that cleaning process is so thorough they damage the vehicle in the process.
So, clean the vehicle, clean it again, clean it yet more BUT if you expect to have to pay to have it cleaned for another day when it gets there 8 weeks later and plan around that life will be a lot easier. If it does get through quarantine without paying for it to be washed consider that a bonus !
