How clean does bike need to be for Australia?

[nico-la-vo]

Hi, we will be shipping our bike to Australia, probably from East Timor in the next couple of months. I'll clean it until its shining but the rubber gators at both ends of the drive shaft have developed pretty big holes. I don't carry any as spares. I've taped it up and that's good for keeping out the dust, but I know that if you were to poke around you'd soon notice the inside of the swinging arm is filthy. Do they expect me to take it off and clean it out / renew gators etc. Are they likely to go sticking their fingers in holes to try and find dirt?

If people think they will then its a job worth doing as I really don't want any expensive troubles over there but its not something I want to be messing with if I can possibly get away with it.
