Adelaide's airport has scheduled international services. Air New Zealand via Auckland is particularly useful for flights to and from the Americas and the Pacific Islands. Cathay Pacific via Hong Kong is generally useful for flights to and from both East Asia and Europe and both Malaysia Airlines and Singapore airlines via Kuala Lumpur and Singapore are useful for flights to and from South East Asia, India, the Middle East and Europe. Qatar also offer flights direct to Doha on the new A350 XWB aircraft, and from there connecting to much of Europe and the Middle East. In addition, domestic flights to Sydney and Melbourne are useful for connections to the Americas, while domestic flights to Perth are useful for connections to Africa. The service to Guangzhou in China is useful for direct entry into China and onward flights throughout Asia.

Great Southern Rail runs long distance tourist train services, The Ghan runs to Alice Springs and Darwin, The Overland, runs to Melbourne, and the Indian Pacific runs to Perth, Broken Hill and Sydney. The The Ghan and Indian Pacific services are train experiences, more like a cruise on rails than a plain transport service, offering sleeper cabins, dining, off-train excursions and the opportunity to take your car with you on the train. However, they take considerably longer and invariably cost more than the journey by bus or plane - a minimum of $800 up to $2500 depending on class of service.
The Overland service to Melbourne is a regular seated day train and while it still takes over 10 hours, the fares can be cheaper than or of comparable price with air fares - starting at $99 each way (red standard class advance purchase). The trains stop at intermediate stops which may not be serviced by air connections. Note that the rest of the train services are very infrequent - running only once or twice per week so you should plan well in advance!
V/Line runs a daily combined bus/train journey to Adelaide from Melbourne. You can connect from NSW TrainLink trains to V/Line buses at Albury or Benalla.
