Morning Crystal didn't dock in Shanghai for that voyage, only Korea and Japan. So I would be fairly confident that there were no Tesla's on Morning Crystal. However, Don Juan which docked in Port Kembla Thursday 26th May did originate in Shanghai. Since I had heard nothing since I had discounted it as having Tesla's. But, if there really are cars in Sydney now, then perhaps Don Juan did have Tesla's on board. I have no experience or knowledge of how long it takes to get cars off the wharf and up to Sydney, it wouldn't surprise me if it took several days. I called my SA last Monday and left a message asking if they could find out what ship my car is on, haven't heard anything since.
So in summary, if there truly are cars in Sydney now, then I think they had to come on Don Juan. If they aren't in Sydney then the best bet (actually the only bet) is that they on Turandot and they should get to Port Kembla this weekend. Either way, it would seem our cars are imminent (at least for Sydney deliveries).
It shouldn't be this hard, I'm sure "someone" in Tesla knows which ships have which VINs, I don't understand why it is such a secret.
