Cooladdi

The town is in the centre of the locality. The Western railway line passes from east to west through the town and locality. The locality was served by a number of railway stations (from east to west):^[7]

The Diamantina Developmental Road (which forms part of the 1578 kilometre (980 mi) Warrego Way State Strategic Touring Route between Brisbane and Birdsville) also passes from east to west through the town and locality.^[7]

The railway station was originally called Yarronvale after a local pastoral station with the town taking its name from the railway station. However, it was renamed in 1913 to Cooladdi, an Aboriginal word meaning black duck, to avoid confusion with the pastoral station, which was 15 miles away.^{[citation needed]}

Cooladdi was a railhead for the local pastoral community. At one time, Cooladdi had a school, post office, and police station with a population of about 270 people. As the railway line extended further west, Cooladdi's role and population declined.^[9]

The Cooladdi State School originally opened on 19 March 1926 as a Provisional School with 9 students under teacher A.W. Marsh. In 1933, a new school building was constructed and the school redesignated as a State School. The school closed on 3 May 1974.^[10][11][12] It was located opposite the railway station on Cooladdi Access Road (26.6404°S 145.4638°E / -26.6404; 145.4638 (Cooladdi State School (former))).^[13]

In 2015, the population was 3 (down from 4 in 2013), all of whom resided at the general store.^[6]

In the 2016 census, the locality of Cooladdi had a population of 16 people.^[14]

In the 2021 census, the locality of Cooladdi had a population of 7 people.^[1]

There are no schools in Cooladdi. The nearest government primary and secondary schools Charleville State School and Charleville State High School respectively, both in Charleville to the north-east. However, only those living in the east of the locality would be within daily commuting range. Other options are distance education and boarding schools.^[7]
