Under the provisions of the Primary Producers' Co-operative Associations Act 1923, in order to continue to use the word "co-operative", the Port Curtis Co-operative Dairy Company Ltd was de-registered under the Companies Act 1863 to 1913, and in February 1925 was re-registered under the 1923 Act as the Port Curtis Co-operative Dairy Association Ltd. In the same year the PCD erected its own cold stores at Gladstone, with storage capacity for 150 long tons of butter.
