"Occupying a prime location next to Sydney’s Darling Harbour, the Australian National Maritime Museum is a must-visit for tourists as well as for local Sydney-siders. As the name suggests, the Australian National Maritime Museum is focussed on Australia’s maritime history, and is home to an impressive collection of objects that go as far back as the 17th century. Note that tickets are required for specific exhibitions and to enter the ships and vessels that are on display inside and outside the museum."
