 The inter-war period built complex in the centre of the national park has aesthetic significance as an example of institutional design in a Mediterranean style, with all the principal buildings hierarchically arranged around a central courtyard on top of a commanding knoll.The complex design is supported by the arrangement of the central driveway which features sandstone gateways from the Officer Training establishment and a central memorial stone obelisk that commemorates the various military forces previously stationed in the complex.The place has a strong or special association with a particular community or cultural group in New South Wales for social, cultural or spiritual reasons.
