These years (1920–70) were marked by transition from Empire to Commonwealth and during that period the Churches marched towards self-support and independence. The Society began to withdraw aid, and by 1941-2 it had been relieved of some 50% of its grants to Canadian dioceses as the Church assumed responsibility. By 1950 the process was virtually complete. Australia experienced the same movement and the process there was complete by 1952. In May 1919 the Bush Church-Aid Society for Australia and Tasmania was founded to alert people in the cities to the needs of the back blocks and to raise funds. Immigrants streamed into Western Australia and Victoria and to meet this need there were some exciting developments followed: setting up of hospitals in four States, Anglican Flying Medical Services (1937–67), the 'Flying Parson' (Leonard Daniels from Woking to Wilcannia, NSW in 1922), the School of the Air, children's Hostels, Mail-bag Sunday School and training of ordinands and women workers. There was growth in East Africa in chaplaincies and the Limuru Girls School, and Sunday School by Post. Also in West Africa in Northern Nigeria and Sierra Leone, and in Japan. Seasonal chaplaincies in Europe reopened in 1920 (France 8, Corfu 1, Italy 3, Portugal 1,Spain 1, Switzerland 23) and the trend rose until the 1930s. But the work was again curtailed by economic conditions and the disturbed political situation in Europe, and it came to an end in 1938. After the War, in 1946, Paris, Cannes, Ostend, Amsterdam and Oslo reopened, but a number of churches were destroyed by enemy action (The Hague by the RAF in error). By 1948 14 permanent chaplaincies reopened and by 1949 five winter and 16 summer seasonal chaplaincies were operating. The grant to the Bishop was renewed in 1919 and when the Bishopric of Fulham was established in 1926 it was renewed again. This was the first time that a bishop was consecrated for control in N and C Europe. In 1948 a grant was made to the Bishop of Gibraltar for travelling expenses. The Package Holiday industry expanded in the 1970s and David Steele was appointed to the staff to develop ministry to tourists. 'Purpose Holidays' were arranged in 1972 and in four years there were 200 people serving in 20 evangelistic teams on campsites at different places throughout Europe In 1983 a new campsite ministry was started under Charles Bonsall linked to a chaplain. Then in 1986 Thompsons 'Young at Heart' programme sponsored chaplains for its clients and services took place in hotel lounges.
