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.
Islington Uniting Church formerly Islington Methodist Church dates from the first subdivision of Reepham in 1880. The building is based on a simple rectangular floor plan. Constructed of coursed random bluestone, it has brick quoins. Lancet windows are used throughout. The church was closed in 2008 and it is now a Sikh Gurdwara offering a free vegetarian meal everyday.
There are four foundation stones on the front of the building. All four stones are visible from footpath. All four stones have the same date AB Oct. CDEF. Check carefully it is the same date. From this information you can determine the location of the geocache.
