In the 1860s to 1883 the area was called Five-Mile Camp. The name Cabarlah was used after
Crows Nest railway line (from Toowoomba to
Crows Nest) was built. It is thought that the name Cabarlah derived from an Aboriginal expression describing the
ring-tailed possum. However, a 1930 newspaper article claims it is a "Native name of the mountains in the neighbourhood". The
Queensland Government set aside land for the Geham Cemetery (now the Cabarlah Cemetery) on 11 September 1878. Trustees were appointed on 2 January 1880 with the first burials occurring in 1881. Highfields No 2 State School opened on 27 March 1871. In 1875 it was renamed Geham State School in 1875. The Borneo Barracks were originally established as a
World War I training area. Cabarlah Post Office opened on 1 July 1927 (a
receiving office had been open from 1884). Since the
Second World War, Cabarlah has also had a significant role as a base for the
Australian Army. It was home to elements of the
7th Brigade early in the war. Later in the war it became a hub for signals and other training. Cabarlah is now home to the
7th Signal Regiment (Electronic Warfare) and other
Australian Defence Force signals facilities. St Martin's Anglican Church was opened at the Cabarlah Barracks in 1959 but closed circa 1961. The Cabarlah Community School opened in Wirraglen Road,
Highfields, on 23 January 2006. == Demographics ==
