Don't know which state your in but this is how it works for WA
Once the vehicle has been bought from auction (and it depends which auction as well) the car is sent to the closest port that ships to W A.
We usually only get one ship or so a month( problem 1) and it leaves Japan on about the 28th and arrive around the 12/14th of the next month.Yes my GTR is due in 2 days.
The car has to be at the holding yard in Japan by about the 25th to get on the ship( problem 2).The broker will get the BL ( bill of lading ) from his Japan contact about 5/7 days before the ship is due in Perth( problem 3).
All going well , it gets offloaded, transported to compliancer and down the licensing centre in about 8/10 days after(problem 4).
Ask your broker if he has the BL yet , if not go back to problem 2 and work from there.
