John Flynn (minister) of the Aerial Medical Service was in 1928 from Cloncurry, Queensland. A museum commemorating the founding of the Royal Flying Doctor Service is located at John Flynn Place in Cloncurry. Flynn married the secretary of the AIM, Jean Blanch Baird, on 7 May 1932 at the Presbyterian Church in Ashfield, Sydney. He was 51 years old and the marriage reportedly came as a surprise even to his close friends. He retired and died in Sydney on 5 May 1951. He was 70 years old. He was cremated and his remains were placed under a large boulder from the Devils Marbles.
Cloncurry Courthouse not reached until the early twentieth century. The township of Cloncurry was established in the early 1870s to serve a remote and isolated area in the far north west of Queensland. It was officially declared a Country Post Office in 1871, and in 1872 a general store and a hotel were opened. Early transportation was by horse, bullock and camel teams, and later by Cobb & Co coaches.The Great Northern railway line to the east coast was not extended to Cloncurry until December 1908. Cloncurry prospered in the 1880s, when prices for pastoral produce remained buoyant and mining activity increased.
