Hi Simon, we shipped from East Timor to Darwin and got through the AQUIS inspection on the first go (according to the shipping company not many people do). If you fail the inspection you have to hire a cleaning bay at the port of entry and don't expect it to be cheap. If the vechicle is too bad it will be sent back to where it came from at your expense. There was a few CAT heavy buldozers being sent back to Singapore from the quarantine area we were in. I've also heard of someone being sent back to India with a landrover. The treated timber should be fine, we had a good few bits which were fine even some untreated plywood which they were OK with. As for how clean, officialy I think its "as new" but in practical terms seeds is what they are most worried about (but seeds can be very small). For us that was about 150hours of cleaning, including removing the air filter and radiator, all trim pannels (dash, door cards etc.) we hired some space in a garage where we had access to a ramp, power washer etc. The container also had to be cleaned and the vechicle put straight inside from the ramp. A complete pain in the arse. maybe we over did it but at least we didn't have to re do it. Talking to other people, they got in a lot easier from South America through Brisbane with a camper. Apparently there are some plants in Timor that AQUIS are particularily worried about, so you might have an easier time.
