Hi Susan
The full reading of 555 (1) (b) is:
(b) land within a national park, historic site, nature reserve, state game reserve or karst conservation reserve (within the meaning of the National Parks and Wildlife Act 1974 ), whether or not the land is affected by a lease, licence, occupancy or use,
“within the meaning of the National Parks and Wildlife Act 1974″ is the important part, look up the definitions under that act and it states:
historic site” means lands reserved as a historic site under this Act.
So in answer to your question it is any land that has been reserved as an historic site under the National Parks and Wildlife Act 1974.
These are done by Gazettal under 33 (4) of the National Parks and Wildlife Act 1974.
