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.

One block of a street in Launceston illustrates the decline in support for churches more that most other areas. The block between St John and Charles Streets on Frederick Street contains three former churches: the Chalmers Presbyterian Church; Christ Church which is currently on the market and Milton Hall which is has also been listed for sale.
Milton Hall
IIn the fifth decade of the nineteenth century, theRev John West was asked to form a new Congregational Church in Launceston. A wooden building was dragged to a nearby site but this Church soon became too small and a new building was opened opposite St. John’s Square. It became known as St. John’s Square Chapel.
The name of the church was changed to Princes Square Congregational Church when the name of the Square was altered. As time passed, the congregation outgrew the church building. In 1885 Christ Church Congregational Church was built next door and the Princes Square Congregational Church was renamed Milton Hall. Milton Hall underwent a renovation in 1899.
Between 1913 and 1916 Milton Hall was one of the campuses of what was to become Launceston College. In 1983 Central Baptist Church bought the Christ Church Congregational Church and Milton Hall buildings and became Christ Church Baptist Church.
As a venue for public meetings, ending convict transportation to Australia, discussing the model for federation and designing and sewing the first version of the Australian flag all took place within the walls of Milton Hall. The flag designed and sewn in Milton Hall is virtually the current Australian flag without the Commonwealth Star.

C = R
D = R - S
E = 2 x R - P

The cache is a short walk away.
Enjoy the stroll.
