I have only imported parts so as for export i can only suggest the mob whom i used to import.

These guys import/export all over the world for the WRC crews and cars. I used them because they know what they are doing.
Another mob is
http://www.schenker.com.au/services/airfreight/airfreight.html
Also a world known logistics comnpany.
There is one more but at present i cannot remember them

Most of them still deal via phone but the two mentioned above are legit and low cost even though they are the bigger mobs.
I would suggest because U r going to Indo the import laws would be little more relaxed, but having the car checked by Australian customs may be worth the $150 or so. We all know about Chapell
Hope this helps.
Keep the steering and the propulsion seperate . Still a Kombi...
It's all good, until it's bad, i suppose
