I can't see why the bus company couldn't liase with the ports authority to create a special bus route that only operates on days when ships are in port. Of course, they'd need to have two timetables - one for changeover days and one for port visits. Start somewhere central, Roma St Station perhaps, with a couple of CBD stops, then cut into Portside for people who used the ferry then onto the BICT. Or is that to logical to be conceivable? 🙄
