Some major points to remember when entering Australia. We have very strict quarantine rules here. When the bike enters Australia (Loose, not crated) it will need to be spotlessly clean and by that I mean as if the bike were brand new off the shop floor, not a speck of dirt anywhere. Quarantine inspectors are from Home Home, they are SS Nazi's when it comes to inspections. If you have the bike crated, the timber must be ISPM15 compliant. The timber will have a stamp on it. Google ISPM15. This stamp indicates that the timber has been treated for any nasty critters that may be in the wood. If you can get hold of a metal crate, do it that way. If you come via East Timor the only way to get to Darwin is through Toll in Dili and they will more than likely place the bike in a sea container uncrated. If the inspectors in Australia find any dirt on the bike you can be sure it will add delays and a major cost to your trip. They will not release the bike until it is cleaned and they will appoint someone to do it for you. If the timber is not ISPM15 compliant they will charge you to have it burnt / destroyed. You have no choice in the matter. If you land the bike in Darwin, the delay could be up to a week and the cost of cleaning your bike will knock you over. Stay Safe and hope this info is of some assistance.
