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
The fine limestone and brick Gothic style St Pauls Lutheran Church opened in Galga in 1924. St Paul’s is now a private residence as is the old limestone public hall but Lutheran services were still being conducted in St Pauls in the mid-1980s.
