This collection of caches is based on the Church Micro series in the UK, which has over 12,000 caches. Given that Adelaide is affectionately known as the City of Churches it seems appropriate to have a small series hidden at historical churches.

St George's Church Magill claims the proud distinction of being the first Anglican Church consecrated in the colony of South Australia. The land on which the Church was built was given by John Finlay Duff, Captain of the Barque Africaine. The foundation stone was laid on the 18th of January 1847 by the wife of Frederick Bayne Esq. of Stradbroke. The original building was completed in one year at a cost of 280 pounds, all from private subscription. Nearby creeks of Magill provided cobblestones to build its walls, and the beams and timbers for its roof are of pit sawn Blue Gum. (https://stgeorgesmagill.org/activities/historical-group/)
