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 former St Petri Lutheran Church/St Petri Kirche, Blyth property is now privately owned. The church building was erected in 1886, on land donated by Mr C B Young, and the tower was added in 1889. The bell was transferred to the Trinity Lutheran Church, Blyth, after the two congregations united in 1966, and the St Petri Lutheran Church was closed. No other details are known.
