Actually it arrived back last Tuesday after a world tour through Madrid, London, Singapore and Sydney. I rode it back from Sydney on Thursday last week.
Getting the bike imported into Australia was extremely expensive and complicated. In the end I ended up engaging a Customs Broker to navigate all the steps required to obtain the bike.
Knowing what I know now, I am not sure I would attempt to import a bike back into Australia again. Certainly I would have to have a long hard think about it.
