“Compulsory registration of births, deaths and marriages started in Western Australia in September 1841. Previously the churches assumed responsibility for recording details of baptisms, burials and marriages. The J S Battye Library in Perth, which is part of the State Library of Western Australia, has certain church records prior to 1841.”
