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.
Forreston Baptist Church building is constructed of coursed with red-brick dressings and a corrugated-iron gable roof. This imposing church was then erected overlooking the township in 1900, with internal dimensions of 37’ by 23’ and an 18’ ceiling. William Jamieson laid the foundation stone on Good Friday (5 April) in 1901. After various meetings and correspondence with the Forreston community, the Baptist Union sold the church to private owners in 1971. During the 1980s, the building was restored by the Mooneys, and it is now used as a residence.
It is not possible to approach the private building. The best view is from the listed coordinates. The cache is nearby. Count the number of vents you can see on the top of the roof. If you can only see one vent the cache is at S34° 47.789 E138° 53.969 . If you count more than one vent the cache is at S44° 47.786 E144° 53.966. Count carefully.
