I didn't have long in Sydney before
heading off to the 'Red Centre' of Australia, but did fit in a
ferry trip to Watson's Bay.
Sydney has a very good transport system, with regular fast ferries
from Circular Quay to many places around the harbour. For
example, you can get to Manly on the JetCat in 15 mins - much faster
than driving. You even get ticket machines and barrier gates at
the quayside - just like on the tube.
