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.
Zion Lutheran Church Monarto is stone building with rendered brick quoins and a corrogated iron roof. The building is now a private residence. The first church on the site was built in 1871. That building lies within the house next door. The church was closed during WW1 because the German language was spoken there. The building was derelect for 40 years and was refurbished with community support in 2012.
