Yep - No ferries! I travel to the Eastern States a bit and people always assume that we have ferries here like over East. There are some tourist ones for river cruises and there is one in South Perth that just comes across to the city and back. There was talk about having ferries from some major river areas to help ease congenstion a few years back eg: Rivervale, Belmont or Midland for the inland ones. Guess it was deemed ineffective.
