The Australian Antarctic aviation system consists of regular intercontinental and intracontinental air services.
An intercontinental Airlink operates from Hobart, Australia to Wilkins Aerodrome near Casey. This route is flown by an Airbus A319-115LR and Royal Australian Air Force C17-A Globemaster III.
The A319 moves approximately 400 passengers each summer season. It can also transport a limited amount of high priority, lightweight cargo. The C17-A can take 72 tonnes of cargo in ‘heavy lift flights’. It can airdrop essential supplies and equipment year-round, including in winter when the stations are usually inaccessible.
Intracontinental services are provided by fixed wing aircraft and helicopters. These link the stations and provide access to other areas of Antarctica for scientific field work.
