Adelaide airport has two main terminals, the domestic terminal (Qantas & Ansett) and the international terminal.
Adelaide airport has direct international flights from South East Asia. Airlines landing at the international terminal include:
A number of other airlines may codeshare with these airlines from Europe.
If you are arriving from North America you will need to transfer to a domestic flight (and pass through customs) in Sydney or possibly Melbourne. In Sydney this will involve a bus transfer between the international and domestic terminals.
As the airport is relatively close to the city of Adelaide (approximately 15 minutes away) most people would transfer to the city using a taxi (cab). The fare should be under AU$10. Taxis in Australia take major credit cards (American Express, VISA, etc) but they charge a 10% surcharge for doing so (which will be added to the fare when the credit card transaction is processed).
The main taxi companies in Adelaide are
If you require a wheelchair capable taxi then contact Access Cabs on 1 300 36 0940.
The nearest taxi rank to the Convention Centre is outside of the Casino's main entrance.
There is a transit bus service provided by Transit Regency which runs every 30 minutes during the week and costs AU$6 one way or AU$10 return.
Most of the hotels selected by the secretariat are clustered around the Convention Centre (with the Hyatt being on site) and are within easy walking distance. Notable exceptions are the Hilton and the Hotel Adelaide.
The Adelaide Hilton International (not to be confused with the pub in the suburb of Hilton :-) is located on Victoria Square in the centre of the city. During shopping hours there are two free public bus services that run from the tram stop in Victoria Square to the suburban train station next to the Hyatt and the Casino. These buses are generally bright yellow and show route numbers 99B (Beeline) and 99C (City Loop). The Beeline has the most direct route, running straight up King William Street, and runs more frequently than the City Loop bus.
The Hotel Adelaide is located in North Adelaide and is the furthest away of any of the hotels. It would be a 15 minute walk from the Convention Centre or a short bus or taxi ride.
