In the 1970s, following its establishment of the National Trust of Western Australia, the National Trust created a set of classified properties, and following legislation requiring inventories, Local Government authorities in Western Australia produced a subsequent set of Municipal Inventories, which then resulted in items then being included in the state register. As a result most register records include dates and details from the three different processes. In some cases authorities other than councils had governance over localities such as Redevelopment authorities, and they also provided Heritage Inventories in that stage of the process. Registration was not always a successful protection. The MitchellsBuilding on Wellington Street was State heritage listed in 2004 but demolished in 2005, with only the facade preserved at another location.
Listings
Places listed on the register include buildings, structures, gardens, cemeteries, memorials, landscapes and archaeological sites. Inherit, the online list of heritage places in Western Australia, contains information about cultural heritage places listed in the State Register of Heritage Places as well as local government inventories, other lists, the Australian Government's heritage list, and other non-government lists and surveys. The Heritage Council of Western Australia, through the Heritage Act 2018, maintains the State Register of Heritage Places, Protection orders and the Heritage agreement while Local governments maintain their Heritage lists and the Australian Heritage Council the National heritage list. Additionally, Municipal Inventories are also part of the listings. As of 2020, the State Register of Heritage Places listed 2367 places, also this number includes sub-listings of individual buildings within heritage listed complexes. Approximately 1,300 places throughout Western Australia are on the State Register, while the database itself contains 25,000 State and local heritage places.
Criteria
The Heritage Council use criteria established in September 1991 to determine the cultural heritage significance of each place, as follows:
