Dairying and grazing continued through the mid-20th Century although restructuring of the dairy industry led to diversification and the development of larger properties. QCWA was arguably the most significant women's organisation in the Upper Logan River and Albert Rivers district. The Wonglepong branch was among the first to be formed in the area, meeting for the first eight years in the home of the founding president, Ann Franklin. By the 1930s, Ann's health problems led members to take turns hosting meetings in their homes. However, transport presented a problem for many and membership had increased so the decision was made to build a hall. A building fund was started and by 1935, £58 had been raised. The hall was built on land leased to the branch by the Franklin family on a 99-year term. The timber for the hall, believed to have originated from the Franklin's property, was milled at Geo Franklin's hardwood mill at Canungra. Franklin, the son of Ann, was the supervising carpenter and members' husbands assisted him on a voluntary basis. The hall was opened on 4 December 1935 by Mrs Buchanan, President of Central Division, QCWA. The branch started a library in the year of the hall's construction. In 1937, the hall was lined and a library cabinet was built with matching hardwood boards sourced from the property. Members donated the furnishings of the hall. These include a number of pews that were made for the branch by E. J. Franklin. The original pattern for the pews is stored in the hall. The President's chair was donated by a member of the Franklin family in memory of his mother, Jane. The creed and motto were painted by Frank Tunley, the brother of the founding Secretary, A. G. Campbell. The hall remains largely intact from the date of its construction and it is comprehensively documented. The library cabinet and lining of the hall have never been painted. The cabinet contains a collection of books most of which date from the period when the library was established. The only substantial changes to the hall have been the addition of a kitchen and the restumping of the hall in 1965, the painting of the exterior in 1975 and the replacement of the corrugated iron roof in 1983. The branch has preserved all of the minutes of meetings since its inception and it is one of the few QCWA branches to have preserved its records for this length of time. From the late 20th Century, the Wonglepong area began to change from a farming community to a rural residential area and since the 1960s membership of QCWA throughout Queensland has declined.
