It wasn't Auz, but I shipped my CBR600 F3 to New Zealand, and rode it around while I was there. It took a bit to sort it out to register it there, like 2 hours or so. Customs were just looking for foreign things that could bugger up the country...bugs in other words, or seeds...They didn't seem to much care about anything else.
Now saying all that, I was the owner, and had always been. Also, totally different country.
Best thing to do is go down and talk to someone if your close. Try to play them off as the one helping you make this happen. Hopefully you have yard close to you.
