Beneath an Utzon-like roof (a low-rent Opera House?), the Maritime Museum sails through Australia’s inextricable relationship with the sea. Exhibitions range from Indigenous canoes to surf culture, to the navy. Entry includes free tours and there are kids' activities on Sundays. The ‘big ticket’ (adult/child $27/16) includes entry to the vessels moored outside, including the submarine HMAS Onslow, the destroyer HMAS Vampire and an 1874 square rigger, the James Craig, which periodically offers sailing trips . Normally a replica of Cook’s Endeavour also drops anchor.
