That’s the first ten houses uploaded. Some are yet to have more detail than a link to their heritage listing.
A search on each of the state’s heritage register did not prove fruitful in identifying further places. However, most registers do not have the ability for a free search so they may be hidden. Out of the first ten, only the Victorian examples of the Monolyte system and the WC Torode Houses in Adelaide appear on registers.
