Ask the dealer ...they should have an internal booking/tracking system that they can look up.
My factory ordered E90 got delivered to Melbourne. Apparently it was built earlier than expected, so they put it on the next available ship which only went to Melbourne. It took a few days to get from the ship to Altona VIC (probably BMW's transport hub) and then a week to get to Sydney. It obviously doesn't take a week by road transport, but they probably ran the service once a week then.
Your car may already be in Altona (or another hub), so it depends how often they run their road transport service.
