If your car has to cross an ocean to get to you, I believe this is a way to track delivery (taken from the pieces I could put together). It should work for US and Canada. Not sure what the Australian lines are.
Once your spec is firm, your dealer should give you a car build schedule. Find the date of the German exit from their port, probably Emden. You probably want to get an updated schedule as the date gets closer. Schedules can change and what you have in January could be different in a couple of months.
On the right side select your trade route (e.g., USA).
For USA and, I think, Canada, select VW Logistics
A PDF schedule will come up. Ask your dealer for the boat name. Look at the schedule column for the date that boat leaves the dock. For example, today it looks like the Gracious Ace
leaves Emden 1/30 and docks in Halifax Canada and then RI. US west coast cars might go to Houston.
. While the ship is near land, you can track it. Not sure how to track it in the open ocean because it uses a different system. There are also apps for smart phones that can track it.
Once the ship is back near land, you can track it until it docks.
Once PDI is done, you can start looking at all the car haulers on the road near you and hope you car is on one of them
I hope this helps somebody interested in tracking delivery of their car (which is different from tracking their car
You can also just google this and find lots of entries where people tracked their delivery.
edit: 21 Nov 2022. my.porsche.com might be able to allow some form of tracking
