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.
Unley Wesleyan church. This building was the first Methodist Church erected in the Unley area. The bluestone building was used a church for many years. The building was replaced in 1880 by a larger church in King William Road, Wayville. After closing as a church the building was repurposed as a Freemasons lodge, and subsequently as the Unley Returned Servicemen's League.
