Macquarie Island, together with a few rocky islets nearby, has constituted a dependency of Tasmania since early in the nineteenth century. In December 1911 five members of the Australian National Antarctic Expeditions had landed on the island and remained there until 1915. The Macquarie Island Station was established in March 1948 by the Australian National Antarctic Research Expeditions (ANARE) as a scientific base.
Agency Components: The Geophysical Observatory at Macquarie Island was established by the Bureau of Mineral Resources in June 1950. The main functions of the Observatory are:
 - the collection and distribution of basic data in the disciplines  of geomagnetism and seismology
 - the application of the data to investigations of local and  regional phenomena
The primary products of the Observatory are analogue recordings of:  - changes in the geomagnetic field (magnetograms)
 - earthquake waves (seisomgrams)
