The Macquarie Island Station, commonly called Macca,[2] is a permanent Australian subantarctic research base on Macquarie Island, situated in the Southern Ocean and located approximately halfway between Mainland Australia and Antarctica, managed by the Australian Antarctic Division (AAD).

[4] Various buildings exist, some dating back to the early 1950s: Sleeping quarters are in Southern Aurora Dongas (SAD), Garden Cove (Dorm), Hasselborough House and Cumpston's Cottage.

[1] The radiocommunications station has callsign "VJM" and conducts a nightly HF radio schedule with the field huts on 3023 kHz (time varies depending on season and staff preferences).

Communications with Australia are conducted using the ANARESAT Earth station facility which utilises the Intelsat Pacific Ocean satellite.

The station was opened in 1911 by Douglas Mawson as his party established a base to relay radio messages from Antarctica to Hobart, Tasmania.
