The Property & Tenancy Registers 1925-1968 collection is housed at Archives ACT. It details all government housing for the period and lists tenants names, rental details and type of house. The collection has been scanned, however not all details have been digitised and as such can not be searches.
You can browse the register by drilling down through the options. To start you choose a region within suburban blocks or rural blocks, for example “Curtin”. You are then provided with an alphabetical list which is sorted by street name. Scroll through the list to find the street name and property number you are looking for. You may then view a scanned PDF of the original handwritten tenancy register which provides the intimate details.
There are still a number of Property & Tenancy Registers yet to be scanned for the Australian Capital Territory.
