This collection of caches has nothing to do with the Church Micro series in the UK. Given that the Australian 2016 census indicates that No Religion and Jedi Knight are the fastest increasing classifications of the optional religion question "What is the person's religion?" it is not surprising that there is surfeit of empty churches that have been repurposed.
Milang Primitive Methodist Chapel. Limestone building from the 1800s. While the Milang Chapel may have been used by the Manchester Unity Independent Order of Oddfellows for meetings, the relationship between the Milang Chapel and the Oddfellows was primarily a financial arrangement. The church probably closed during union in the early 1900s. For some time the building housed the Milang telegraph office. The building has been restored and is now headquarters for the Milang and District Historical Society, where it stores an extensive collection of documents and photographs.
The plaque by the door lists two years ABCD and WXYZ. Use that information to calculate the final cache location.
