high school and the intermediate school". In the 1950s the number of high schools in Queensland increased significantly. Reflecting the connected growth of suburbanisation and a move towards a decentralised population in urban centres, new high schools were located in suburban areas rather than the centre of town. The grounds were large, greater than , providing ample room for sports facilities. The general classroom buildings were the same standard types as used for primary schools but high schools also included purpose-built science laboratories, domestic science buildings, workshops for woodwork and metal work, libraries, and gymnasiums. These were also built to standard plans but were specific to their use and not a continuation of previous designs. Cairns' population continued to increase in the post-World War II period: rising from 16,644 in 1947 to 21,018 by June 1954, with the percentage increase being greater than any other Queensland city for that period. Post-war migrants from Europe were housed at the Immigration Holding Centre on Hartley Street. The city also expanded physically. The anti-malarial drainage scheme undertaken southwest of Severin Street during World War II allowed the suburbs to expand westwards after the war. Tourism to Cairns also increased in the 1950s and 1960s, with the Great Barrier Reef being promoted as a destination by the Queensland Government. The "Sunlander" rail service, a tourist service between Brisbane and Cairns, began in 1953; an underwater observatory was opened on nearby Green Island in 1954; and in the early 1960s the Bruce Highway was bitumened to Cairns. After the 1950s, the Cairns Technical College and High School grew considerably and many new buildings were added. Also, alterations to the Cairns Technical College and High School building were made, including enclosing part of the understorey for a tuckshop (1966), and an extension above the toilets of the Sheridan Street wing to accommodate home science classrooms (1972). The extension used bricks similar to those of the 1941 portion but it was in a contemporary style. The addition of floors above one-storey toilets was an occurrence at other brick Depression-era schools and was possibly an intention of the original design, to accommodate future expansion. Technical education expanded from the 1960s through a concerted push by the Queensland Government. In 1974 all Queensland technical colleges were renamed Technical and Further Education (TAFE) Colleges. In the early 1980s the Cairns TAFE College moved off site to new premises. This allowed
