The peak of the 11-year solar cycle results in increased geomagnetic activity which is evidenced by significant geomagnetic storms and frequent aurora sightings at lower latitudes. The importance of understanding and monitoring the Earth's magnetic field during these periods is emphasised due to the key role it plays in applications such as navigation, mineral exploration, natural hazard mitigation, space weather monitoring, and scientific research.

Australia has made significant contributions to the science of geomagnetism through early exploration and long-term monitoring, particularly in the Australian and Australian Antarctic Territories. This article details the operations of Geoscience Australia (GA), which manages a network of 10 geomagnetic observatories, including three in the Australian Antarctic and sub-Antarctic regions. It also explores the concept of the South Magnetic Pole, its historical measurements, and its movement over time.
