This collection of caches has nothing to do with the Church Micro series in the UK. Given that the Australian 2021 census indicates that No Religion and Jedi Knight are still 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.
