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.
Highgate Congregational church
Foundation stone 28 May 1927 by Elliot A Aitchison. Brick building. The spiritual centre of Highgate Village. Became Uniting Church in 1977. Deconsecrated in 1989 . Now a wondrous two-level 4-bedroom family home, with a tennis court, spa and pizza oven for good measure.
