  ## History
  
  The locality was named and bounded on 27 July 1991. It was presumably named after the now-abandoned Calcium railway station (19°40′32″S 146°50′05″E﻿ / ﻿19.6756°S 146.8348°E﻿ / -19.6756; 146.8348﻿ (Calcium railway station)) on the Great Northern railway, which had been named prior to 1914 after the calcium-bearing lime that was mined in the area.
  
  Manton takes its name from the now-abandoned Manton railway station (19°39′26″S 146°50′03″E﻿ / ﻿19.6573°S 146.8341°E﻿ / -19.6573; 146.8341﻿ (Manton railway station)), which takes its name from a pioneer farmer.
  
  In the 2016 census, Calcium had a population of 21 people.
