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.
A small Bible Christian Methodist church was built in Cooke Plains in 1869 and from 1873 a school operated in it. A new stone church replaced the smaller building. The Primitive Methodist Church was cement rendered in the 1950s and closed in 2000.
From the plaque on the building collect the following information (Take care. You need the older date).
