List of Sydney Harbour ferries
Sydney Harbour's first ferries were sail and/or oar powered, but by the mid-19th century, paddle steamers were well established. Double-ended ferries became common as they did not require turning at terminating wharves in Sydney's busy but narrow bays, including at the main hub at Circular Quay.
