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. The Northern Territory Department of Public Works had taken the rock from a site sacred to its traditional owners, but after many years of negotiations the rock was returned to its original location in 1998. It was replaced with one acceptable to the Aboriginal people, both of the original rock's home and the people on whose land his grave lies. The land adjoining the grave site was proclaimed as a reserve on 21 March 1957 and became a historical reserve known as the John Flynn's Grave Historical Reserve on 30 June 1978. His widow Jean died at the Pitt Wood Presbyterian nursing home in Ashfield, Sydney, New South Wales on 27 August 1976. Flynn was appointed an Officer of the Order of the British Empire in 1933. The work of the Australian Inland Mission (AIM) is continued today through the Uniting Church of Australia's Frontier Services and the Presbyterian Church of Australia's Presbyterian Inland Mission. The Royal Flying Doctor Services still continues to deliver Flynn's vision of a 'Mantle of Safety' to the people of outback Australia.
