could be that they are just going to put them on a truck from BNE. Don Juan has it's slot on Monday so plenty of time to get them into all locations by Friday.
I can't imagine that they'd have them in country too long before they'll want to show them off, so I'm thinking it has to be a ship arriving this week.
If it's one of the earlier ships that have been in transit prior to Don Juan it would suggest they are much further ahead of schedule to be producing AU vehicles, I don't really put too much faith in that idea, but it would be nice.
