Australian Antarctic Division
The Australian Antarctic Division occupies a portion of Antarctica for the advancement of Australia's strategic, scientific, environmental and economic interests in the Antarctic by protecting administering and researching the region.
Australia maintains three stations on the Antarctic continent – Mawson, Davis, and Casey – and a subantarctic station on Macquarie Island. All have modern buildings with living quarters, research laboratories, power houses, stores, workshops and other operational facilities. Remote field bases operate during the summer research season, supporting coastal, inland and traverse operations.
HF is the main mode of communications between Macquarie Island station and the island's field huts. On the continent it is used to talk between the stations and field parties outside VHF range that are not equipped with satellite terminals and, in some cases, for low capacity data transmission.
HF is used to communicate with aircraft flying between Antarctic stations and, in the future, will be used to communicate with aircraft flying between Hobart and Casey. A daily SKED is conducted on 3023 between Macquarie Island station and field huts.
Most communications to the Australian mainland, however, are conducted via ANARESAT (Intelsat/Inmarsat/Iridium Satellite).
