Most airlines do not allow hand-carry due to the size. The only place it fits is the upright closet, where usually reside in the business class, unfortunately. However, I think some people may have persuaded airlines to let them hand-carry, but I wouldn't count on that. Good padded hard-case, fragile stickers, and really, hope for the best. That's how I did it. Going to Australia should be safe. Travelling to and within China is the most dangerous. I had to sign a tag saying that the airlines and airport are not responsible for any damages, even with the fragile sticker on - which really defeats the purpose of having any fragile stickers in the first place...
