Royal Australian Navy Heritage Centre, Maritime and military museum in Potts Point, New South Wales, Australia.

The Royal Australian Navy Heritage Centre is a maritime and military museum in Potts Point, Sydney, displaying ship models, naval equipment, and historical objects. The collections cover Australia's naval history from its early days to more recent operations.

The idea for a dedicated naval museum goes back to 1922, when Vice Admiral Sir William Creswell first called for one. The centre finally opened in 2005, after an official study into naval heritage management recommended its creation.

The centre displays uniforms, personal items, and photographs that show what daily life looked like for sailors at sea. These objects make the Navy feel less distant and more human for visitors of all ages.

The centre closed permanently in 2021 because of access problems inside the working Garden Island naval base, so it can no longer be visited. Its displays, including the submarine periscope and the Japanese midget submarine fin, are no longer open to the public.

The centre's periscope exhibit was a fully operational submarine attack periscope, installed so visitors could look out over Sydney Harbour. It was not a reconstruction: the instrument came from a submarine, and looking through it showed how narrow a crew's field of view was.
