Looking at past history, I’ve followed 3 shipping theories in the past for 3 tesla deliveries. On each occasion I was advised that the vessel had just left, but have never had confirmation of the vessel name. Oddly on each occasion the portal said my car had just left the factory as it came off the boat. Model 3 is probably treated differently as they arent made to order as such, but any model s or x buyers awaiting an end of august delivery should see the same changes in their portal.
Curiously on all three occasions the departure to deliver time was always the same (within a day or two), and tesla always just made it in time based on the original promised date.
To keep it simple, my most recent tesla was promised ‘end of september last year’. It departed 17 august and arrived with me 26 sept including a day from melb to adelaide. It arrived in adelaide 23rd sept late at night. I didnt stay up or stalk the yard. Note the ship went nz - melb - syd so adelaide was about the same time as sydney. The previous delivery was nz-syd-melb.
On this historical basis, and given all tesla models and variants are currently promised end of august, a ship should leave around 17 july. The cars will all be made ‘just in time’. I dont have a car on order this time, but my best guess is Seoll express on 15 july or Cap Capricorn (this boat already hosted my tesla) on 22 july. You will know the vessel once our good friends in NZ start recieving notifications to collect. It could also be cars are on both these ships.
