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.
Some history
Twin churches Mount Bryan
In 1913 land was donated for a new Methodist church and a wood and iron building called the ‘Cook House” was opened. It served the Methodists until a Romanesque style red brick church was opened next door in 1938.
